ABSTRACT

This report documents an analysis of the performance of safety-related motor

operated valve assemblies (valve body and motor operator subcomponents) used in 

the pressurized water reactor (PWR) and in the boiling water reactor (BWR) risk

important (RI) systems in U.S. commercial power reactor plants. 

A risk-based analysis of operating data and an engineering analysis of trends and 

patterns were done to provide insights into the performance of motor-operated valve 

components on an industry basis and the results were compared with data used by 

plant-specific probabilistic risk assessments. The engineering analysis of the PWR 

and the BWR RI systems used data from 1987-1995. Failure probability estimates 

used combined engineered safety features data (1987-1998) and surveillance test 

data (1987-1995).

EXECUTIVE SUMMARY 

This report provides the performance evaluation based on industry experience 

during the 1987 through 1998 period for motor-operated valves (MOVs) in the 

pressurized water reactor (PWR) and in the boiling water reactor (BWR) risk

important (RI) systems. The objectives of component performance studies are (1) to 

determine the reliability of risk-important components and compare the results with 

estimates in probabilistic risk assessments (PRAs) developed to support the 

individual plant examinations (IPEs) and (2) to review the operational data from an 

engineering perspective to determine trends and patterns, and gain insights into 

component performance. 

MOV failure and estimated demand data were obtained from two databases. The 

Nuclear Plant Reliability Data System (NPRDS) provided data on component 

failures and surveillance test frequencies for the 1987-1995 period. The Sequence 

Coding and Search System (SCSS) provided engineering safety features (ESF) 

failure and demand data for the 1987-1998 period and some surveillance test failure 

data for the 1987-1995 period reported in Licensee Event Reports (LERs). 

For the PWR and BWR RI systems, the MOV estimated probability of failure on 

demand distributions were consistent with the generic value range from 

NUREG/CR-4550 (used as an input to NUREG-1 150). Table ES-A lists the MOV 

probability of failure on demand estimates developed for the RI systems selected for 

this study and the NUREG/CR-4550 values. Table ES-B gives the standby failure 

rates for each system.

The yearly trend analysis of the MOV probability of failure on demand showed no 

statistically significant trends for the PWR AFW, HPI, and RHR systems or for the 

BWR RCIC and RHR systems. Statistically significant trends (decreasing) were 

identified for the PWR CVCS, RCS, and CS systems (see Figure ES-1) and for the 

BWR HPCI, HPCS, CS, and LPCS systems (see Figure ES-2). The data for these 

downward trends was examined to determine the appropriate value to use for the 

probability of failure on demand and identified that the majority of the decrease 

occurred in the first three years. An examination of the last six years identified no 

statistically significant trends. Therefore, the mean value over the 1987-1998 

period was used. 

The MOV mean probabilities of failure on demand used in plant-specific IPE studies 

were compared with the results of this study. PWR and BWR IPE mean values 

were generally consistent with the results of this study and NUREG/CR-4550 

generic values. Figures ESS-3, ES-4, and ES-5 show a sample of RI systems for the 

PWR AFW, PWR CS, and BWR HPCI systems, respectively. 

The number of complete MDV common-cause failures (CCF) identified in this study 

was consistent with the expected number based on the CCF database parameters for the combined PWR and BWR complete failure population used in this study.

COMPARISON WITH VALUES USED IN IPEs 

The number of failures in PWR and BWR RI systems during the 1987-1995 period showed statistically significant decreasing trends (see Figure ES-6). Both the Maintenance Rule and voluntary industry joint owners group (JOG) initiatives were begun during the period. While there was insufficient information available to conclude whether these initiatives caused the trend, an improvement had occurred.

PWR AND BWR MOV FAILURE TRENDS

xiv
For both PWRs and BWRs, an analysis of failure rates, as a function of component

years, did not show evidence of an increase for any plant age groups (three groups 

of approximately equal size, from older to newer plants by commercial operation 

date) due to aging mechanisms. 

The motor-operator subcomponent was the biggest contributor (approximately 90%) 

to MOV failures in both PWRs and BWRs. Figure ES-7 shows the PWR and BWR 

motor-operator subcomponent failure apportionment. For PWR motor-operators, 

torque switches (30%) were the predominant subcomponent part that failed; while 

for BWR motor-operators, motor internals (28%) were the predominant part that 

failed.

FOREWORD

This report provides information relevant to the performance of motor-operated valves 

(MOVs). It summarizes the failure and event data used in the analysis and evaluation. 

The results, including failure probabilities and engineering insights, are intended to 

support several risk-informed regulatory activities. This includes providing information 

to enhance plant inspections of risk-important systems and information used to support 

staff technical reviews. 

Findings and conclusions from the analysis of MOVs, which are based on 1987-1998 

operating experience, are presented in the Executive Summary and Section 5. The 

results of risk-based analysis and engineering analysis are presented in Sections 3 and 

4, respectively. Information to support risk-informed regulatory activities and 

engineering analysis related to MOVs is summarized in Table F-I. This table provides 

a condensed index of risk-important data and data for engineering insights in the text 

discussions, tables, figures, and appendices. 

The application of results is intended on an industry-wide basis for MOVs. Plant

specific application may require a more detailed review of the relevant Licensee Event 

Reports (LERs) and in-plant validation of plant-specific Nuclear Plant Reliability Data 

System (NPRDS) failure history data cited in this report. Factors such as design and 

application of specific MOVs, test and maintenance practices, availability, and response 

to regulatory initiatives would need to be considered in light of specific information 

provided in LER and NPRDS failure records. Other documents such as plant 

specifications, logs, reports, and inspection reports should be reviewed during plant 

inspections to supplement the information contained in this report. 

In addition, a review of recent LERs and plant-specific information in NPRDS or the 

Equipment Information Exchange (EPIX) may yield indications of whether performance 

has undergone a significant change since the last year of this report. A search of the 

LER database can be conducted through the NRC's Sequence Coding and Search 

System (SCSS) to identify the MOV events that occurred after the period covered by 

this report. SCSS is accessible by NRC staff from the SCSS home page 

(http://scss.ornl.gov/). Nuclear industry organizations and the general public can obtain

COMPONENT PERFORMANCE STUDY 

MOTOR-OPERATED VALVES, 1987-1998 

1. INTRODUCTION 

1.1 Purpose 

This report provides the performance evaluation of motor-operated valve 

(MOV) assemblies in the pressurized water reactors (PWR) and in the boiling 

water reactors (BWR) risk-important (RI) systems during the period 1987 

through 1998. The objectives of this study are: (1) to determine the reliability 

of MOV assemblies and compare the results with estimates in probabilistic 

risk assessments (PRAs) and individual plant examinations (IPEs) and (2) to 

review the operational data from an engineering perspective to determine 

trends and patterns and gain insights into component performance. 

This report provides an engineering analysis of the factors affecting 

component reliability and determined whether trends and patterns were 

present in the MOV operating data for the 1987-1995 period. This study was 

based on the actual operating history of MOVs for these safety-related, RI 

systems. The reliability parameters calculated in this study are the probability 

of failure on demand and standby failure rate. Supplemental failure and 

demand data for 1996-1998 from operational events (Engineered Safety 

Features actuations reported in Licensee Event Reports) were added to the 

1987-1995 data for estimating the MOV probabilities of failure on demand 

when the data populations were the same. 

1.2 Background 

The U.S. Nuclear Regulatory Commission (NRC) PRA Policy Statement directs 

the staff to increase the use of PRA technology in all regulatory matters. 

Accordingly, the Office of Nuclear Regulatory Research (RES), Division of Risk 

Analysis and Application (DRAA) monitors and reports on the functional reliability 

of risk-important systems in commercial nuclear power plants. The approach is 

to compare estimates to actual operating experience. 

Over the past decade, the NRC has issued studies applicable to MOV risk

important systems, MOV components or their subcomponent failures, failure on 

demand probabilities, and trends and patterns. The following provides a listing

2. SCOPE OF STUDY

2.1 Risk-Important Systems and Components 

Risk-important (RI) systems were selected from a review of safety-related 

PWR and BWR systems. Application Coded MOVs were used in this study 

because of the consistency in reporting failures and identifying demands that 

are linked to these failures. The term "Application Coded" used in this study 

refers to risk-important components or subcomponents that are functionally 

designated within a specific system by the NPRDS. An example of the PWR 

RHR system MOV subcomponents that were separately Application Coded in 

NPRDS are as follows: 

COMP. SUBCOMP. REACTOR TYPE RI SYSTEM APPLICATION 

ASSY CODE 

DESCRIPTION 

MOV Valves,damper PWR RHR RHR Disch Isol 

Valve 

MOV Valve operator PWR RHR RHR Disch Isol 

Valvop 

The following PWR Risk-Important (RI) systems use Application Coded 

MOVs: 

* auxiliary/emergency feedwater (AFW) system 

* high pressure safety injection/safety injection (SI) system 

* containment spray (CS) system 

* chemical and volume control system (CVCS) 

* residual heat removal/low pressure injection (RHR) system 

* reactor coolant system (RCS - for pressurizer power operated relief 

valve block valves only) 

For this study, the HPI system includes MOVs associated with high head 

safety injection flow paths. 

The following BWR RI systems use Application Coded MOVs: 

* high pressure core spray (HPCS) system 

* low pressure core spray (LPCS) system 

* high pressure coolant injection (HPCI) system 

• containment spray (CS) system 

• reactor core isolation cooling (RCIC) system 

* residual heat removal/low pressure core injection (RHR)

3
PWR and BWR RI systems that do not have Application Coded MOVs are 

excluded from this study. Non-Application Coded MOVs (typically motor

operated butterfly valves) include PWR and BWR service water systems (NSW/ESW) and component cooling water systems (CCW/RBCC) MOVs. 

2.2 MOV Assembly Description and Boundaries 

Within the scope of this study, a MOV assembly consists of valve body and 

motor-operator subcomponents (excludes the circuit breaker). The valve 

circuit breaker was excluded because: (1) It is not an Application Coded 

subcomponent and, therefore, failure reporting is not consistent, (2) it 

normally does not change state to operate the valve, and (3) it plays no 

significant role in the risk-significant function of the valve (to open or close on 

demand). The valve body is generally a gate type. The motor-operator is 

generally a Limitorqlue or a Rotork alternating current (AC) or direct current 

(DC) motor actuator, designed to accommodate the system 

pressure/temperature requirements and the thrust requirements necessary for 

the valve's functional operation. 

The component boundaries are the MOV assembly, its subcomponents described above, and the piece parts of the subcomponents. The piece parts of the valve body are the stem, packing, and internals. The motor-operator 

piece parts include torque switch, spring pack, limit switch, wiring/contacts, 

motor internals, and mechanical devices. 

2.3 DATA COLLECTION 

Data collection and reporting for the Nuclear Plant Reliability Data System (NPRDS) were termiinated at the end of 1996. Therefore, the NPRDS does 

not have any failure information for the period 1997 and later. Furthermore, 

the 1996 failure data reported in NPRDS was not as consistent as for the 

1987-1995 period (the industry was transitioning for the termination of 

NPRDS. The Institute for Nuclear Power Operations (INPO) has recently implemented a new component database called Equipment Performance and 

Information Exchange (EPIX). This system is intended to replace the NPRDS 

system and yields additional information, such as demands and unavailability. 

At the time of this analysis, the EPIX system was not considered to be 

sufficiently mature to provide a complete data source for the 1996-1998 

period for this study. Where applicable in the development of probability of 

failure on demand estimates for this study, the Sequence Coding and Search 

System (SCSS) database of ESF failure and demand data (reported in LERs) 

was used for the 1996-1998 period.

4
The NPRDS database was used to obtain the number of Application Coded 

MOV assembly subcomponents. This was done for each selected RI system 

in PWRs and BWRs for each plant. The values developed in Appendix IV 

were also used in the development of all other appendices. 

A detailed review and evaluation was performed of the licensee event reports 

(LERs) and the NPRDS failure histories to determine the total number of 

MOV failures used in this study. Only "complete" (i.e., catastrophic) failures 

were included in the failure count. For MOV valve body and motor operator 

subcomponents, the NPRDS "failure to close" (FC), "failure to open" (FO), 

and "failure to operate as required" (OR) failure modes were used for 

estimating probability of failure on demand. The OR failure mode meant that 

the valve could not open or close. Figure 1 illustrates the relationship 

between various NPRDS database failure data subsets.

NPRDS DATABASE MOV FAILURES 

The SCSS database (1987-1998) was used to determine the number of MOV 

failures, reported in LERs, that occurred during surveillance tests or that were 

associated with an engineered safety features (ESF) actuation. Surveillance 

test failures that were reported in LERs were excluded from the NPRDS 

failure counts, but included in the LER failure counts. This was done to 

prevent "double count" of failures. Figure 2 illustrates the relationship 

between various SCSS database (LERs) failure data subsets.

with 

MOV failures that occurred during surveillance testing were directly linked surveillance test demands to ensure that surveillance test probability of failure 

with ESF 

on demand estimates were valid. Similarly, ESF failures were linked 

most 

demands to estimate ESF probability of failure on demand. For 

Those 

plant RI systems there are multiple trains, each train with several MOVs. 

post-test 

other train MOVs that might have been actuated during pre-test or system train alignment were not included in the surveillance test failure counts. 

When 

demands 

it was 

were 

detemlined by statistical means that the ESF failures and in the same population as the surveillance demands, test failures and the total riumber of demands was the sum of the ESF demands and the surveillance test demands. Otherwise the larger population of surveillance test demands (and associated failures) was used to calculate MOV reliability. 

The first step for estimating ESF demands was to determine ESF actuations, and then to determine which component each type and how many components of 

have 

type 

occurred 

were actuated by this type of demand. Other demands that may durincg plant operation, startup, or shutdown that did not result 

were 

in ESF actuations were not included in the ESF demand determination, nor 

demands 

any associated failures included. However, inadvertent and spurious 

were 

and manua~l actuations associated with an ESF (e.g., a reactor trip) 

PWR 

considered 

and BWR 

ESF demands. The SCSS LER database was used for the 

those coded 

RI systems LERs that were coded with "ESF Actuations" and as "SCRAMS and Shutdowns." Each LER full text was reviewed to determine whether the selected systems were actuated; the number of 

Application 

trains actuated by the ESF; and the best estimate of the number of each Coded MOV actuated, based on the plant-specific train configuration. 

The 

NPRDS 

second step in estimating the total number of demands was the use of testing frequencies as the basis for surveillance 

was test demands. This done for the NPRDS Application Coded, functionally designated MOV assembly subcomponents 

description 

in the RI systems (see Section 2.1 for the 

assembly 

of the MOV assembly). An estimate was made for the MOV testing frequency that used the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code, Section XI Inservice Testing (IST) interval requirements (as required by the Technical Specifications), the system, and the subcomponent assembly. Demands function in the MOV associated with a surveillance test that occurred during 

not 

train alignment and return to the "as found" condition of a system/train were included in the total number of demands, nor were corollary failures included in the failure count. Although the Technical Specifications generally

6
require a system flow test once per refueling cycle, no additional demands 

were included because the surveillance test frequencies used in this study 

(e.g., monthly, quarterly, and once per refueling outage) were assumed to 

envelop these refueling cycle demands. Special tests, applicable to valve 

operability testing per Generic Letter (GL) 89-10, were separately identified 

for engineering evaluation. 

The total number of demands for the MOVs in a specific system was the sum 

of MOV ESF demands and surveillance test demands, where the latter is the 

sum of the products of the MOVs and their estimated testing frequencies over 

the 9-year period (1987-1995), and the former (ESFs) is extended to the 12

year period (1987-1998). However, this method is applicable when the ESF 

data and surveillance test data are determined by statistical methods to be in 

the same population (see Section 3.1 for contingency tests). Otherwise, the 

surveillance test demands (and associated failures) were used to calculate 

the MOVs unreliability. Special test data were excluded from this data set 

because of inadequate linkage of failure data to demand data. 

The probability of failure on demand for MOVs was estimated by dividing total 

MOV failures by total MOV demands (i.e., ESF failures + surveillance test 

failures divided by ESF demands + surveillance test demands) when the ESF 

data and surveillance test data were statistically shown to be in the same 

population. Valves generally need only to change state to fulfil their risk

significant safety function. Therefore, calculation of failure-to-run/operate 

probabilities was not included in this study. 

Surveillance tests and ESF actuations do not typically reflect design-basis 

conditions. This report estimates the probability of failure to perform risk

significant functions of MOVs in risk important systems. ESF actuations, and 

surveillance tests that reasonably replicate ESF actuation conditions, are 

used to calculate that probability. Therefore, they do not characterize the 

ability to perform under design-basis conditions, which are generally more 

severe and occur less frequently than the risk-significant safety function 

condition. 

2.4 Operational Data Analysis 

A contingency test was performed to not reject or to reject the hypothesis 

that failure and demand data from surveillance testing of Application Coded 

MOVs were in the same population as ESF failure and demand data. The 

analysis was performed using data for the MOVs in the PWR and BWR RI 

systems during the 1987-1995 period. A subsequent contingency test was 

performed to determine whether ESF data from the 1996-1998 period is in the

7
same population as the combined ESF plus surveillance test data from the 

1987-1995 period. 

The approximate method for contingency tables (chi-square, one degree of 

freedom, 0.95 quantile), was used for the not reject hypothesis that the ESF 

and surveillance test data are from the same population (X2 < 3.84). The 

contingency table provides a short-cut method of computing chi-square using 

the following 2X2 table and formula: 

X = n (ad - bc) 2 ; where: n = a + b+ c+ d and k = (a+b)(c+d)(a+c)(b+d) k

TOTAL (a + c) (b + d) n 

(DEMANDS) 

Alternate Method (to correct for continuity): 

X2-= n (Cad-bcl - n12) 2 

k 

Bayes Method 

The Bayes method (Ref. 7), as applied to this study for MOVs by plant 

system, assumes that the probability of failure on demand varies from plant to 

plant according to a beta distribution. The parameters for this distribution 

were estimated from the pooled data by maximum likelihood. For each plant, this distribution was used as a Bayes prior distribution, and updated with the 

plant-specific failure data. This method was used in this study for the PWR 

and BWR RI systems. 

Standby Failure Rate 

The average standby failure rate (A) for MOVs in each system is based on the 

data for the 9-year period (1987-1995), using the following equation: 

A = f __, failures per component-hour 

(nc)(coy)(8760)

8
where: f = the number of failures during the period 

nc = the number of MOVs in each plant for the system 

coy = the actual number of calendar operating years during the 9-year period 

8760 = the number of hours in a calendar year 

The 90% confidence interval was also calculated for A in each system. 

3. RISK-BASED ANALYSIS 

This section provides the risk-based analysis of operational data, the calculation 

results for estimating MOV probabilities of failure on demand and standby failure 

rate, the contingency test for the data population, the comparison of MOV 

probability values with those in IPEs and other sources, and the regulatory 

implications of this component performance study. 

3.1 Calculation Results 

Appendix I provides tables applicable to the MOV Probability of failure on 

demand for the selected systems in the PWR and BWR plants. The summary of 

results of the contingency tests for the hypothesis that ESFs and surveillance 

test data are in the same population is as follows: 

PWR RI SYSTEM HYPOTHESIS BWR RI SYSTEM HYPOTHESIS 

HPI Not Rejected HPCS Not Rejected 

AFW Not Rejected HPCI Not Rejected 

RHR/LPI Not Rejected RCIC Not Rejected 

CVCS Rejected LPCS Not Rejected 

CS No ESF Data RHR/LPCI Not Rejected 

RCS No ESF Data CS No ESF Data 

For PWR CVCS MOVs, during the 1987-1995 period, the contingency test 

rejected the hypothesis that the ESF failures and demands were in the same 

population as the surveillance test failures and demands. For PWR plant CVCS, 

there were relatively sparse ESF demands. The more extensive surveillance test 

data (1987-1995) was used for probability of failure on demand estimates. For 

the PWR CS and RCS (PORV block valves only) and BWR CS systems, there 

were no ESF failures or ESF demands, and the surveillance test data was also 

used for these systems. 

For the balance of PWR and BWR RI systems, the contingency tests did not 

reject the hypothesis that the ESF failures and demands were in the same 

population as the surveillance test failures and demands. Therefore, the Bayes 

90% intervals for ESF + surveillance test (1987-1995) + ESF (1996-1998) 

probability of failure on demand was used for these systems.

9
The generic failure probabilities used in PRAs are presently provided in terms of 

probability of failure on demand and probability of failure per operating hour. In 

this study, probability of failure on demand was used because data were 

available to allow matching failures to demands. Sufficient data on hours of 

operation from LERs and NPRDS were not adequate to compare with generic failure rates. The generic failure probability on demand values used in this study 

are from NUREG/CR-4550 "failure to operate" values for motor-operated valves 

(Ref. 8).

3.2 MOV Yearly Trends 

The yearly trend analysis of the MOV probability of failure on demand showed 

no statistically significant trends for the PWR AFW, HPI, and RHR systems or 

for the BWR RCIC and RHR systems. Statistically significant trends 

(decreasing) were identified for the PWR CVCS, RCS, and CS systems (see 

Figure 3) and for the BWR HPCI, HPCS, CS, and LPCS systems (see Figure 

4). The data for these downward trends was examined to determine the 

appropriate value to use for the probability of failure on demand and identified 

that the majority of the decrease occurred in the first three years. An 

examination of the last six years identified no statistically significant trends. 

Therefore, the mean value over the 1987-1998 period was used. The 

bounds on the graphs for yearly trends represent confidence intervals for the 

trend line. They are different from the bounds calculated for the probability of 

failure on demand for the entire period, They differ because: (1) Each year 

has fewer data points than the total period, causing different values for the 

bounds and (2) In trending analyses the bounds are wider at the beginning 

and at the end of the plot. This reflects the greater uncertainty of the trend 

values at the ends versus the middle because of having less information on 

both sides of the mean estimate for a given year.

3.3 MOV Common-Cause Failure Events 

The review of the common-cause failure (CCF) database for the 1987-1995 

period found eight complete MOV failures that were within the selected RI 

systems in the scope of this study's criteria (e.g., Application Coded MOVs 

with complete failures, failure modes of FC, FO, or OR, and occurred during 

surveillance testing or an ESF). This is consistent with the expected number 

of CCFs within the combined PWR and BWR failure population (312). Failure 

causes associated with these 8 failures were not significantly dfferent from the 

causes of single failure. Table C lists all MOV failures in the CCF database 

(with the complete failures applicable to this study in boldface). CCF numbers 

that include XXX denote that the source is the NPRDS database, and the 

docket number is not disclosed. For these CCFs, the plant identification (PLT ID) number gives the coded identifier for the plant for which the docket 

number is listed as XXX. Table C also references the Appendix IV table and 

item number for the complete failures within the scope of this study.

3.4 Comparison With IPEs and Other Sources 

The MOV failure probabilities on demand developed for the PWR and BWR 

RI systems were compared with a selected group of plant-specific 

probabilistic risk assessment (PRA) values (mostly point estimates) 

developed to support the Individual Plant Examinations (IPEs), as shown in 

Figures 5 through 16. The PWR and BWR plants IPE mean values were 

generally consistent with the results of this study and the NUREG/CR-4550 

generic values. 

This comparison reflects readily available (docketed) IPE/PRA information. 

Licensees which have updated their IPE/PRAs without providing docketed 

information relating to MOVs are not reflected in this comparison.

4. ENGINEERING ANALYSIS 

This section provides the engineering analyses including failure trend analysis, component trends in time, the failure characteristics and their 

causes, a brief discussion and listing of NRC regulatory initiatives related to 

MOVs, and engineering insights resulting from the various analyses. 

4.1 Failure Trend Analysis 

Appendix III provides applicable data for trending of MOV failures. 

As indicated in Section 2.3, NPRDS failure data for 1996 was reported inconsistently by licensees and, therefore, was determined to be insufficient 

for trending purposes. Without NPRDS data, LER data from 1996 through 1998 was insufficient for trending purposes. Therefore, failure data for 

trending in this study used NPRDS and LER failure data for the 1987-1995 

period. 

For the PWR and BW R RI systems during the 1987-1995 period, there was a statistically significant decreasing trend in the number of failures. Both the Maintenance Rule and voluntary industry joint owners group (JOG) initiatives 

were begun during this period. While there was not sufficient information to conclude whether these initiatives caused the decreasing trends, it is noted that 

an improvement in performance occurred. The increase in 1992 is consistent 

with nominal statistical year-to-year variation. A review of the data for that year did not attribute any single cause to this variation. Figure 17 shows the MOV 

failure trends for the '1987-1995.

4.2 Component Trends in Time

Methodology 

The initial assumption made in this study, relative to aging effects on 

component assemblies, was that the rate of failure events over time (A) is 

constant. Several evaluation methods were used to check this assumption. 

The reason for checking was to determine if any significant age-related 

increase in A occurred among older plants. In order to conclude that an 

increase due to aging occurred, it would be necessary for all three of the 

following conditions to be present: 

(1) There was an increase in A over time (a nonconstant failure rate that 

was increasing). 

(2) A was higher for older plants. 

(3) The dominant contributor to failure was due to age/wear mechanisms. 

When individual failure events are arranged in chronological order, a 

cumulative plot helps to show whether A is constant throughout the period. 

This study used an average failure rate, AAVE., equal to the total number of 

MOV failures for the 1987-1995 period, divided by the cumulative number of 

MOV component- years of standby operation during the period. Failure data 

from the 1996-1998 period was not included, as it was for ESF failures and 

limited surveillance test failure data only reported by LERs. 

The cumulative number of failures was plotted against the number of MOV 

component-years since the beginning of the study period (1987) for 

comparison with AAVE. This was done for PWRs and BWRs with plant age 

groups A, B, and C. These groups include 109 plants used as a basis for 

component studies with compilation of the number of MOV component-years 

for each specific plant. The following table gives the definition of each plant 

age group and its apportionment, in the 109-plant basis: 

PLT AGE COMMERCIAL TOTAL NUMBER OF NUMBER OF PWR NUMBER OF BWR

B 01/01175 through 37 25 12 

03/31/84 

C 0410184 and later 36 24 12

23
The assumption (i.e., null hypothesis) that AAVE. is constant during the study 

period for each plant age group was evaluated. The failure rates (AAvE) are 

the slopes of the plots for each plant age group. Comparison between plant 

age groups were made to determine whether there was any indication of plant 

aging (e.g., higher slope for the older plant age groups than for the newer 

plant age groups). Another test for the null hypothesis that the failure rate is 

constant is the Laplace test. For this test, L/2 is defined as the midpoint of the 

cumulative number of component-years during the 1987-1995 period. If A is 

constant, about half of the events should occur before L/2 and half afterwards. 

The criteria for not rejecting the null hypothesis is that the statistic U is 

approximately normal for a number of failures > 3 (U is within + 1.645 for the 

0.95th and 0.05th quantiles, respectively, of the standard distribution). For a 

nonconstant failure rate (rejected null hypothesis) that is increasing (U 

>+1.645), possible aging exists. The formula for the U statistic is as follows: 

U = T - U/2 where: in = no. of failures, Ti = interval between failures in component-years, 

L V 1/12n T = E Ti In 

The mean time between failures was provided for information, using the 

reciprocal of the AAm5. applicable to each PWR and BWR plant age group and 

the combined plant age groups. 

Results 

Appendix II provides tables applicable to component trends in time 

evaluations for MOV's. These analyses were performed to determine whether 

the failure rates were constant over time, and whether the failure rates 

between older and newer plant age groups increased as an indication of 

possible aging. A comparison of plots of cumulative MOV failures over time 

to the applicable average failure rate (AAVE.) plots for PWRs and BWRs 

indicated the following results: 

PWRs (see Figure 18 and Appendix II, Tables I-Ill) - For the PWR RI 

systems, an analysis of failure rates did not show evidence of an increase in 

failure rates for any of the plant age groups due to aging mechanisms. 

For plant age group A, the assumed hypothesis that the failure rate 

was constant was rejected (decreasing). The value of U at the 10% 

significance level was -4.049 (<-1.645). The nonconstant failure rate is 

decreasing; therefore, there is no evidence of an increased failure rate 

due to aging mechanisms.

24
For plant age group B, the hypothesis of a constant failure rate was 

rejected (decreasing). The value of U at the 10% significance level was 

-2.734 (<-1.645). The nonconstant failure rate is decreasing; therefore, 

there is no evidence of an increased failure rate due to aging 

mechanisms. 

For plant age group C, the hypothesis of a constant failure rate was not 

rejected. The value of U at the 10% significance level was 

-1.360 (>-1.645), and did not show any evidence of a nonconstant 

failure rate. 

When the average failure rates were compared among the plant age 

groups, plant age effects were assumed to be reflected by highest 

average failure rates for the older plant age group A, ranging to the 

lowest average failure rate for plant age group C. Differences 

occurred, where AAVE. for A (0.013) was higher than B (0.008), and C 

(0.007) and B was slightly higher than C. This is indicative of a higher 

failure rate for older plants, but the trends (above) were constant or 

decreasing, and the causes (below) were not dominated by age/wear 

mechanisms. 

When the failure causes for PWR MOV assemblies were reviewed, 

maintenance/procedural deficiencies (23%), age/wear causes (23%), 

and unknown causes (21 %) were the more significant causes (see 

Figure 23). Therefore, age/wear mechanisms were not the 

predominant cause of failure. 

BWRs (see Figure 19 and Appendix II, Tables IV-VI)) - For the BWR RI 

systems MOVs, an analysis of failure rates did not show evidence of an 

increase in failure rates for any of the plant age groups due to aging 

mechanisms. 

For plant age group A, the assumed hypothesis that the failure rate 

was constant was rejected (decreasing). The value of U at the 10% 

significance level was -3.527 (<-1.645). The nonconstant failure rate is 

decreasing; therefore, there is no evidence of an increased failure rate 

due to aging mechanisms. 

For plant age group B, the hypothesis of a constant failure rate was 

rejected (decreasing). The value of U at the 10% significance level was 

-2.014 (<-1.645). The nonconstant failure rate is decreasing; therefore, 

there is no evidence of an increased failure rate due to aging 

mechanisms.

25
For plant age group C, the hypothesis of a constant failure rate was 

rejected (decreasing). The value of U at the 10% significance level was 

-3.021 (<-1.645). The nonconstant failure rate is decreasing, therefore, there is no evidence of an increased failure rate due to aging 

mechanisms. 

When the average failure rates were compared among the plant age 

groups, plant age effects were assumed to be reflected by the highest 

average failure rates for the older plant age group A, ranging to the 

lowest average failure rate for plant age group C. Differences 

occurred, where AAVE. for A (0.013) was higher than B (0.010), and C 

(0.009) and B were slightly higher than C. This is indicative of a higher failure rate for older plants, but the trends (above) were constant or 

decreasing, and the causes (below) were not dominated by age/wear 

mechanisms. 

When the failure causes for BWR MOV assemblies were reviewed, 

maintenance/procedural deficiencies (30%), unknown causes (19%), 

and age/wear causes (14%) were the more significant causes (see 

Figure 24). Therefore, age/wear mechanisms were not the 

predominant cause of failure. 

The analysis indicates no evidence to conclude that "aging" is adversely affecting the failure rate of MOVs in this report because the failure rates were not increasing 

over time and age/wear mechanisms were not the predominant cause of failure. It 

is not clear whether this is due to a lack of "aging" impacts or whether 

replacement/refurbishment of MOVs is responsible for the lack of an "aging" trend. 

Since specific component age information is not available, no additional assessment 

of causes for the lack of trends was performed.

4.3 Failure Characteristics and Their Causes

Methodology 

The MOV assembly failures and their causes were identified on a 

subcomponent level in the NPRDS database. For LER reported failures 

(SCSS database), sufficient information was provided to identify failed 

subcomponents and causes within the LER narrative, and to group these 

failures using the NPRDS categories. The apportionments were determined 

to provide insights into the predominant subcomponent failures and their 

causes by reactor type (i.e., PWR and BWR). 

The failure cause categories used in this study were as follows: 

Age/Wear (AW) DirtlContamination/Corrosion (DC) 

Design Deficiency (DD) Manufacturing Defect (MF) 

Unknown (UK) Debris/Foreign Material (DF) 

Out-of-Adjustment (OA) Mechanical Linkage (ML) 

Other Devices (OD) Maintenance/Procedural Deficiencies (MP) 

Initial Installation (11) 

Results 

Figure 20 shows the MOV subcomponent failure apportionment for the PWR 

and BWR RI systems. Figures 21 and 22 show the MOV subcomponent 

parts failure apportionment for PWRs and BWRs, respectively. For both 

PWRs and BWRs, the evaluation of MOV subcomponent failure patterns 

determined that motor-operator failures accounted for approximately 90% of 

all MOV subcomponent failures. Fewer failures in the valve body, indicate that 

MOV valve body structural weakness and unreliability was a less significant 

concern than the motor-operator capability. For PWR motor-operators, torque 

switches (30%) were the predominant subcomponent part that failed; while for 

BWR motor-operators, motor internals (28%) were the predominant 

subcomponent part that failed. 

Failure causes for all MOV assemblies, based on reported failures, are 

illustrated in Figures 23 and 24 for PWRs and BWRs, respectively. For the 

PWR RI systems, the causes were mainly due to maintenance/procedural 

deficiencies (23%), age/wear (23%), and unknown (21%). For the BWR RI 

systems, the causes were mainly due to maintenance/procedural deficiencies 

(30%), unknown (19%), and age/wear (14%).

4.4 Related Issues

Generic Letters and Information Notices 

The review of NRC regulatory initiatives related to MOV assemblies and their 

subcomponents included Generic Letters (GLs), Circulars, Bulletins, and 

Information Notices (INs) was performed for the 1987-1998 period. This 

review determined that there were no Circulars or Bulletins involving MOVs 

for this period. The review determined that there were MOV failures reported 

by LERs associated with GL 89-10 that were within the scope of the failure 

population used in this study. Briefly, this scope was limited to Application 

Coded MOVs in PWR and BWR RI systems that failed completely 

(catastrophically) with "failure-to-open," "failure-to-close," or "failure-to-operate 

as required" failure modes, and occurred during ESF actuations, surveillance 

tests, or special tests associated with GL 89-10. 

The LER reported failures that are applicable to GL 89-10 and within the 

scope of this study are included in Appendix IV. These specific LERs are: 

333-92002, 361-92006, 302-92004, 275-92010, 305-93011, and 369-94008. 

No other GLs or INs were applicable to reported failure events within the 

scope of this study. Table D lists the GLs and INs that are applicable to all 

safety-related MOV assemblies and their subcomponents.

NRC and Industry Initiatives 

An improvement was indicated in the overall frequency of failure and in the 

probability of failure on demand for most systems. There were several industry and 

regulatory initiatives implemented at various times during the observed period of 

improving performance. However, this study could not causally link the initiatives to 

the performance improvements using the set of failures within the scope of this 

study. 

In addition, many of the initiatives were focused on design basis capability, rather 

than the risk-significant functional reliability which was the subject of this analysis. 

While it is plausible that changes made in response to these design basis issues also 

improved the risk-significant functional reliability, the data is insufficient to establish 

cause and effect relationships.

5. SUMMARY OF RESULTS

5.1 Failure Probabilities 

For the PWR and BWR RI systems, the MOV estimated probability of 

failure on demand distributions were consistent with the generic value 

range for MOVs from NUREG/CR-4550 (used as an input to NUREG

1150). 

The yearly trend analysis of the MOV probability of failure on demand 

showed no statistically significant trends for the PWR AFW, HPI, and RHR 

systems or for the BWR RCIC and RHR systems. Statistically significant 

trends (decreasing) were identified for the PWR CVCS, RCS, and CS 

systems and for the BWR HPCI, HPCS, CS, and LPCS systems. The data 

for these downward trends was examined to determine the appropriate 

value to use for the probability of failure on demand and identified that the 

majority of the decrease occurred in the first three years. An examination 

of the last six years identified no statistically significant trends. Therefore, 

the mean value over ;the 1987-1998 period was used. 

The MOV mean probabilities of failure on demand used in plant-specific 

IPE studies were compared with the results of this study. The PWR and 

BWR IPE mean values for R! systems were generally consistent with the 

results of this study and the NUREG/CR-4550 generic values. 

5.2 Engineering Insights 

The engineering insights gained from this study are summarized as follows: 

For the PWR and BWR Rl systems during the 1987-1995 period, there 

was a statistically significant decreasing trend in the number of failures. 

For both PWRs and BWRs, an analysis of failure rates, as a function 

of component-years, did not show evidence of an increase for any 

plant age groups (three groups, of approximately equal size, from 

older to newer plants by commercial operations date) due to aging 

mechanisms. 

The number of complete MOV common-cause failures (CCF) 

identified in this study is consistent with the expected number based 

on the CCF database parameters for the combined PWR and BWR 

complete failure population used in this study.

38
The evaluation of MOV subcomponent failure patterns demonstrated 

that motor-operator failures were significant contributors 

(approximately 90%) to MOV failures in both PWR and BWR RI 

systems. Fewer failures in the valve body, indicate that MOV valve 

body structural weakness and unreliability was a less significant 

concern than the motor-operator capability. For PWR motor

operators, torque switches were the predominant subcomponent 

part that failed; while for BWR motor-operators, motor intemals were 

the predominant part that failed. 

For reported failures, failure causes for MOV assemblies in PWR RI 

systems were mainly due to maintenance/procedural deficiencies, 

age/wear, and unknown causes.

NOTES: 

1 For the 1987-1995 period, the contingency test accepted the hypothesis that the ESF failures 

and demands were in ]he same population as the surveillance test failures and demands for 

the AFW, RHR, and HPI systems. Since the contingency test for the 1996-1998 ESF data was 

also accepted for the AFW and RHR systems, the probability of failure on demand data 

combined the surveillance test data for 1987-1995 with ESF data for 1987-1998. For the HPI 

system, the contingency test for the 1996-1998 ESF data was rejected and the combined ESF 

and surveillance test data for 1987-1995 was used. 

2. For the 1987-1995 period, the contingency test rejected the hypothesis that the ESF failures 

and demands were in the same population as the surveillance test failures and demands for 

the CVCS system. There was no ESF data (failures or demands) for the CS and RCS systems. 

The surveillance test data (1987-1995) was used for estimating the probability of failure on 

demand for these four systems. 

3. The 90% confidence intervals (Chi-Square) are provided for information. The Bayes 90% 

intervals are used in this study for RI system estimated probability of failure on demand.

the listed systems. Since the contingency test for the 1996-1998 ESF data was also accepted, 

the probability of failure on demand data combined the surveillance test data for 1987-1995 

with ESF data for 1987-1998. 

2 The 90% confidence intervals (Chi-Square) are provided for information. The Bayes 90% 

intervals are used in this study for RI system estimated probability of failure on demand.

ABBREVIATIONS USED IN APPENDIX IV - TABLES I THROUGH IV

Column Headings: 

ESFISURV/ - Failure occurred with ESF, Surveillance Test, or Special Test 

SPTST (associated with GL 89-10). 

PLT ID NO. - Numerical identifier assigned to each selected plant used with 

NPRDS failure histories. When source is from LERs, a 3-digit 

docket number is used. 

DATA SRC - Data Source, either as NPRDS failure history (FHIS) or as a 5-digit 

LER number, as applicable. 

PLT AGE - Plant Age Group (A, B, or C) that indicates the plant commercial 

licsense date.as follows: 

A - 12/31/74 and earlier. B - 1/1175 through 3/31/86 C - 4/1186 and later 

PLT SYS - The selected risk important (RI) system in which the component 

failed (see text list of acronyms for system abbreviations). 

NO. FAIL - Number of same subcomponents failed.with same failure mode, 

system, date, etc. 

DISC DATE - For NPRDS failures, this is the discovery date and for LERs, this is 

the event date, shown by month and year only (i.e., 0189 is January 

1989, etc.). 

SUB COMP - Subcomponent of the MOV assembly (VB - Valve Body and VO 

Motor Operator). 

COMP PART - Subcomponent part. These are as follows: 

Valve Bodies NB) Motor Operators (MO)

10. SUPPLEMENTARY NOTES

11. ABSTRACT (200 words or less) 

This report documents an analysis of the performance of safety-related motor-operated valve assemblies (valve body and 

motor operator subcomponents) used in pressurized water reactors (PWRs) and boiling water reactors (BWRs) in U.S. 

commercial power reactor plants. 

A risk-based analysis of operating data and an engineering analysis of trends and patterns was performed to provide insights 

into the performance of motor-operated valve components on an industry basis and comparison of results with data used by 

plant-specific probabalistic risk assessments. The data used in this report was from the 1992-1995 period for engineering 

analysis of riisk-important systems, Failure Probability estimates used combined engineering safety features data (1987-1998) 

and surveillance test data (1987-1995).
