ABSTRACT

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

driven pump assemblies (pump, motor, and circuit breaker subcomponents) used in 

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

important 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-driven pump 

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

plant-specific probabilistic risk assessments. The engineering analysis of selected 

risk-important systems used data from the 1987-1995 period. Failure probability 

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

surveillance test data (1987-1995).

EXECUTIVE SUMMARY

This study provides the performance evaluation based on Industry experience 

during the 1987 through 1998 period for motor-driven pumps (MDPs) 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) 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. 

MDP failure and estimated demand data was 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 MDP probability of failure on demand 

estimates were based on the combined ESF and surveillance test data failures and 

demands from SCSS and NPRDS data sources, except for the PWR residual heat 

removal and nuclear service water systems'and the BWR residual heat removal 

system. For these exceptions the surveillance test data was used because the ESF 

data was sparse. 

The MDP probability of failure on demand estimates were consistent with the 

generic values from NUREG/CR-4550 (used as an Input to NUREG-1 150), with two 

exceptions. The values for the BWR reactor building closed cooling water system 

were lower than the generic values and the mean value for the high pressure core 

spray system washigher.than the generic values. Table ES-A lists the MDP 

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

this study and the NUREG/CR-4550 values. 

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

for PWR and BWR RI systems, except for the PWR high pressure injection (HPI) 

system. The HPI system showed an increasing trend through the 1987-1995 period. 

The end point of the trend is still within the expected range of the generic values in 

NUREG/CR-4550.

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

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

generally consistent with the results of this study and NUREG/CR-4550. 'The IPE mean 

values for BWR RI systems were also consistent with the results of this study and-, NUREG/CR-4550, except for the RHR and RBCC systems. Sixty percent of the IPE 

mean values for the BWR RHR system were higher than the RHR system value range estimated in this study. Most (approximately 89%) of the IPE mean values for the 

RBCC system were higher than the RBCC system value range estimated in this study. 

Figure ES-I (AFW system) is indicative of the systems where there was general agreement between the sampled IPEs and our analysis of operating experience. Figures ES-2 and ES-3 show BWR RHR and RBCC systems noted above, respectively.

Failure trends for the PWR and BWR RI systems during the 1987-1995 period were 

relatively constant, except for an upward peak in 1992 and 1993 for PWRs and in 1993 

for BWRs. Figure ES-4 shows the MDP failure trends for the 1987-1995 period.

Failure rates, as a function of component-years, varied slightly among the PWR and 

BWR plant age groups (three groups, of approximately equal size, from older to newer 

plants by commercial operations date). For PWRs and BWRs, the review of plant age 

groups did not show evidence of an increase in failure rates for any of the plant age 

groups due to aging mechanisms. 

The evaluation of MDP subcomponent failure patterns demonstrated that circuit 

breakers were significant contributors to the MDP failures in both PWR and BWR RI 

systems (greater than 75%). 

Failures of MDP assemblies in PWR RI systems were mainly attributed to unknown 

causes (43%) because a root cause analysis was generally not performed on the 

predominant failed subcomponent (circuit breaker). Age/wear and 

maintenance/procedural deficiencies together accounted for the bulk of the balance 

(43%). For BWR RI systems, age/wear was the predominant cause (43%), while 

unknown causes and maintenance/procedural deficiencies together accounted for the 

bulk of the balance (46%). Figure ES-5 shows the MDP assembly failure causes for 

PWR and BWR RI systems.

FOREWORD

This report provides Information relevant to the performance of motor-driven pumps 

(MDPs). 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 MDPs, 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 MDPs is summarized in Table F-1. This table provides 

a condensed index of dsk-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 MDPs. 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 MDPs, 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 MDP events that occurred after the period covered by 

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

(http://scss.oml.govA) or in the Public Document Room (PDR). Nuclear industry 

organizations and the general public can obtain Information from the SCSS on a cost 

recovery basis by contacting the Oak Ridge National Laboratory directly. NPRDS 

archival data (through 1996) and EPIX failure data is proprietary Information that can be 

obtained from the EPIX database through the Institute of Nuclear Power Operations 

(INPO).

COMPONENT PERFORMANCE STUDY- MOTOR-DRIVEN PUMPS, 1987-1998 

I. INTRODUCTION 

1.1 Purpose 

This study provides the performance evaluation of motor-driven pump (MDP) 

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 MDP 

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. 

An engineering analysis of the factors affecting component reliability was 

performed to determine trends and patterns In the MDP operating data for the 

1987-1995 period. This study was based on the operating history of MDPs 

for these safety-related, RI systems. The reliability parameters calculated in 

this study are the probability of failure to start on demand and failure rate per 

standby hours (standby failure rate). Supplemental failure and demand data 

for 1996-1998 from operational events (engineered safety features actuations 

reported in Licensee Event Reports) was added to the 1987-1995 data for 

estimating the MDP probabilities of failure on demand. 

1.2 Background 

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

the staff to increase the use of probabilistic risk assessment (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 from PRAs to actual 

operating experience. 

Over the past decade, the NRC has issued several studies applicable to MDP 

risk-important systems, MDP components or their subcomponent failures, failure 

on demand probabilities, and trends and patterns:

1
AEOD/S98-02 (INEEL/EXT-95-00133), "High Pressure Core Spray 

System Reliability, 1987-1993," dated May 1998 (Ref. 1), documented 

an analysis of the performance of the BWR HPCS system during the 

period 1987-1993. Both a risk-based analysis and an engineering 

analysis of trends and patterns were done, using HPCS system 

operational events data (reported by LERs), to provide insights into the 

performance of the HPCS system throughout the industry and at a 

plant-specific level. 

* NUREGICR-5500, Vol. 1, "Reliability Study: Auxiliaiy/Emergency 

Feedwater System, 1987-1995," dated August 1998 (Ref. 2),

documented an analysis of the performance of the PWR AFW system 

during the period 1987-1995. Both a risk-based analysis and an 

engineering analysis of trends and patterns were done, using AFW 

system operational events data (reported by LERs), to provide insights 

into the performance of the AFW system throughout the industry and at 

a plant-specific level. 

NUREG/CR-5500 (INEELIEXT-99-00373, "High Pressure Safety 

Injection System Reliability, 1987-1997 (DRAFT)," dated May 1999 

(Ref. 3), documented an analysis of the performance of the PWR HPI 

system during the period 1987-1997. Both a risk-based analysis and 

an engineering analysis of trends and patterns were done, using HPI 

system operational events data (reported by LERs), to provide insights 

into the performance of the HPI system throughout the industry and at 

a plant-specific level. 

1.3 Overall Study Structure 

This study has four sections: 

(1)_ Section 1 is the introduction. 

(2) Section 2 describes the scope of the study, risk-important systems, the

2. SCOPE OF STUDY 

2.1 Risk-Important Systems and Components 

The PWR risk important (RI) systems that use the MDPs are the 

auxiliarylemergency feedwater (AFW) system, the component cooling water 

(CCW) system, the containment spray (CS) system, the chemical and volume 

control system (CVCS), the residual heat removal/low pressure injection' 

(RHR) system, the nuclear service water (NSW) system, and the high 

pressure safety injection/safety injection (HPI) system. For this study, the HPI 

system includes intermediate head safety injection pumps or charging/high 

head safety injection pumps. The CVCS system includes charging pumps for 

plants that also have intermediate head safety injection pumps in the HPI 

system. 

The BWR RI systems that use MDPs are the essential service water (ESW) 

system, the high pressure core spray (HPCS) system, the low pressure core 

spray (LPCS) system, the reactor building closed cooling water (RBCC) 

system, and the residual heat removal/low pressure core injection (RHR) 

system. The HPCS system, with a single MDP train is used In newer BWR 

plants as a replacement for the high pressure coolant Injection (HPCI) system 

that used a turbine-driven pump (TDP) train. 

2.2 MDP Assembly Description and Boundaries 

For this study, a MDP assembly consists of pump, motor-driver, and circuit 

breaker subcomponents. The pumps are all centrifugal, but some types have 

horizontal single stage and multiple stages, and some types have vertical 

single stage or multiple stages. The motors are medium or large AC 

horizontal or vertical motors, as required to accommodate the pump type and 

supply the required rated horsepower.

3
The component boundaries are the MDP assembly with the subcomponents 

(described above) that are supplied as part of the MDP assembly. For most 

plants, the AFW system MDP assembly includes a speed increaser which is 

treated as a subcomponent. 

2.3 DATA COLLECTION 

Data collection and reporting for the NPRDS were terminated at the end of 

1996. 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, that is intended 

to replace the NPRDS system, yields additional information, such as 

demands. In its present stage of development, the EPIX system was not 

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 SCSS database ESF failure 

and demand data (reported in LERs) were used from the 1996-1998 period. 

The NPRDS database was used to obtain the number of MDP assembly

subcomponents and the estimated testing frequency for each subcomponent 

in each plant. The number and testing frequency of Application Coded pump 

subcomponents were compared with the number and testing frequency of 

Application Coded motor driver and circuit breaker subcomponents for each 

MDP assembly. This was done for each RI system in PWRs and BWRs for 

each plant. This comparison was made to ensure that the number of MDP 

assemblies was correct for each plant, as each assembly has one pump, one 

motor, and one circuit breaker. The values developed in Appendix IV were 

also used in developing the other appendices. 

The term "Application Coded" refers to risk-important components or 

subcomponents that are functionally designated within a specific system by 

the NPRDS. An example using the PWR RHR system MDP subcomponents 

that were separately Application Coded in NPRDS is as follows:

A detailed review and evaluation was performed of the LERs and the NPRDS 

failure histories to determine the total number of MDP failures used for this 

study. Only "complete" (i.e., catastrophic) failures were included in the failure 

count. For MDP pump and motor subcomponents, the NPRDS 'lail to start" 

(FS) and "fail to run" (FR) failure modes were both included for estimating 

probability of failure on demand. Because these failure modes occurred in a 

relatively short period, these pump and motor subcomponent failure modes 

were considered as equivalent to "fail to start." For the MDP circuit breaker 

subcomponent, the "failure to close" (FC) and "failure to operate as required" 

(OR) failure modes were used. Figure 1 illustrates the relationship between 

various NPRDS database failure data subsets.

NPRDS DATABASE MDP FAILURES 

The SCSS database was used to determine the number of MDP failures, 

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

associated with an engineered safety features (ESF) actuation. The NPRDS 

database was used to obtain the number of surveillance test failures for each 

MDP subcomponent. Surveillance test failures reported in LERs were 

excluded from the NPRDS failure counts, but included in the LER failure 

counts. This was done to prevent a "double count" of failures. Figure 2 

illustrates the relationship between various SCSS database failure data 

subsets that were reported by LERs.

MDP failures that occurred during surveillance testing were directly linked with 

surveillance test demands to ensure that surveillance test probability of failure 

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

ESF demands to estimate ESF probability of failure on demand. For most 

plant RI systems, there are multiple MDP trains. These other, redundant 

MDPs, which might have been actuated during pre-test or post-test system 

train alignment, were not included in the surveillance test failure counts used 

inthis study. 

When it was analytically determined that the ESF failures and demands were 

in the same population as the surveillance test failures and demands, the total 

number of demands was the sum of the ESF demands and the surveillance 

test demands. Otherwise, surveillance test demands (and associated 

failures) of the larger population were used to calculate the MDP unreliability 

because the ESF data was determined to be relatively sparse for component 

performance evaluation. 

The first step in estimating ESF demands was to identify ESF actuations and 

then determine which component types and how many components of each 

type were actuated by ESF demands. Other demands that may have 

occurred during plant operation, startup, or shutdown but did not result in ESF 

actuations were not included in the ESF demand determination, nor were any associated failures included. However, inadvertent and spurious demands 

and manual actuations associated with an ESF (e.g., a reactor trip) were 

considered ESF demands. The SCSS database was used for the PWR and 

BWR RI systems for- LERs that were coded as "ESF Actuations" and those 

coded as "SCRAMS and Shutdowns." The full text of each LER was 

reviewed to determine whether the selected systems were actuated, the 

number and type of trains (e.g., for AFW, the turbine-driven pump train(s) 

and/or the motor-driven pump train(s) actuated by the ESF), and the best 

estimate of the number of each MDP actuated based on the plant-specific 

train configuration]. 

The second step in estimating the total number of demands was to use 

NPRDS testing frequencies as the basis for surveillance test demands. This 

was done for the NPRDS Application Coded, functionally designated MDP 

assembly subcomponents in the RI systems (see Section 2.1 for the 

description of the MDP assembly). The NPRDS testing frequency was 

reviewed for each subcomponent of the MDP assembly (i.e., pump, motor 

driver, and circuit breaker). When the NPRDS reported testing frequency 

differed among the subcomponents, an estimate was made for the MDP 

assembly testing frequency that included the American Society of Mechanical 

Engineers (ASME) Boiler and Pressure Vessel Code, Section XI Inservice 

Testing interval requirements (as required by the Technical Specifications), 

the system, and the subcomponent function in the MDP assembly. When no

6
frequencywas given by NPRDS, a minimum frequency of once per quarter 

was used. Demands associated with a surveillance test that occurred during 

train alignment and return to the "as found" condition of a system/train were 

not included in the total number of demands, nor were corollary failures 

included in the failure count. Although the Technical Specifications generally 

require a full flow test once per refueling cycle, no additional demands were 

included because the surveillance test frequencies used in this study (e.g., 

monthly or quarterly) were assumed to envelop these refueling cycle 

demands. 

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

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

sum-of the products of the MDPs and their estimated testing frequencies over 

the 9-year period (1987-1995) and the former (ESFs) covers 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 4.1 for contingency tests). 

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

MDP failures by total MDP demands [(ESF failures + surveillance test 

failures) + (ESF demands +surveillance test demands)] as long as the ESF 

data and surveillance test data were determined to be in the same population. 

2.4 Operational Data Analysis 

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

hypothesis that failure and demand data from surveillance testing of 

Application Coded MDPs were in the same population as ESF failure and 

demand data. The analysis used surveillance test data for the MDPs in the 

PWR and BWR RI systems during the 1987-1995 period and ESF data from 

the 1987-1998 period.. 

The approximate method for contingency test tables (chi-square, 1 degree of 

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

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

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

using the following 2X2 table and formula:

7
X n (ad - bce) k, where n = a + b+ c+ d and k = (a+b)(c+d)(a+c)(b+d) .- k

ESFs SURVEILLANCE TEST TOTAL 

NO. of a b (a + b) FAILURES 

NO. of c d (c9d) SUCCESSES 

TOTAL (a + c) (b + d7 n 

(DEMANDS) 

Alternate Method (formula to correct for continuity): x= n (I ad-bcl . ni 2 

k 

Bayes Method 

The Bayes method (Ref. 4), as applied for MDPs 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 RI system, this 

distribution was used as a Bayes prior distribution and updated with the plant

specific system failure data. 

Standby Failure Rate 

The average standby failure rate (A) for MDPs 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 

(ncXcoy8(8760) 

where 1= the number of failures during the period 

no = the number of MDPs 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

3. RISK-BASED ANALYSIS

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

estimated MDP probabilities of failure on demand and estimated standby 

failure rate, the contingency test analysis for the data population, and the 

comparison of MDP probability values with those in IPEs and other sources. 

3.1 Calculation Results 

Appendix I provides tables applicable to the MDP probability of failure on, 

demand by the selected RI systems in the PWR and BWR plants. The 

results of the contingency test analysis for ESFs and surveillance test data in 

the same population are as follows: 

PWR RI SYSTEM HYPOTHESIS BWR RI SYSTEM HYPOTHESIS 

HPI Not Rejected HPCS Not Rejected 

AFW Not Rejected RBCC Not Rejected 

RHRILPi Rejected ESW Not Rejected 

CVCS Not Rejected LPCS Not Rejected 

CS Not Rejected RHR/LPCI Rejected 

CCW Not Rejected 

NSW Rejected 

For the PWR and BWR plants, 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 MDPs in 

RHR systems (see Section 4.1). The reason for this disparity appears to be 

the sparseness of ESF data, since most RHR functions are performed during 

shutdown and have few ESF actuations. For the PWR NSW system, the 

rejection is also due to relatively sparse data, since ESF actuation signals do 

not constitute a demand of a running NSW system. As stated earlier, the 

more extensive surveillance test data (1987-1995) was used for probability of 

failure on demand estimates 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 (see Section.4.1). 

Therefore, the Bayes 90-percent intervals used for this studyused ESF data 

from 1987-1998 and surveillance test data from 1987-1995. 

The 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 for MDPs because 

data was available to match failures with demands. Data on run times from 

LERs and NPRDS was not available to compare with generic failure to run

9
data. The generic failure probability on demand values used in this study are 

from NUREG/CR-4550 (Ref. 5), which was an input to NUREG-1 150. 

Table A shows the MDP probability of failure on demand values for the 1987

1998 period for the selected RI systems.

The results shown in Table A indicated that the Bayes 90-percent interval 

probabilities of failure on demand were generally consistent with the generic 

NUREG/CR-4550 values referenced in this study, except the BWR RBCC 

system value was lower and the mean value and upper bound value for the 

HPCS system was higher. 

Appendix I gives calculated standby failure rates for the selected PWR and 

BWR RI systems. 

The MDP yearly trend analysis for probability of failure on demand showed no 

trend for PWR and BWR RI systems, except for the PWR HPI system. The 

HPI system showed an increasing trend through the 1987-1995 period (see 

Figure 3, below). The end point of the'trend is still within the expected range 

of the generic values in NUREG/CR-4550.

3.2 Comparison With IPEs 

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

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

plant examinations (IPEs), as shown in Figures 4 through 15. The IPE mean 

values for PWR plants were generally consistent with the results of this study 

and the NUREG/CR-4550 generic values. 

The IPE mean values for the BWR RI systems were also generally consistent 

with the results of this study and NUREG/CR-4550, except for the RHR and 

RBCC systems. Sixty percent of the IPE mean values for the BWR RHR 

system were higher than the RHR system value range estimated in this study. 

Most (89%) of the IPE mean values for the RBCC system were higher than 

the RBCC system value range estimated in this study.

4. ENGINEERING ANALYSIS 

This section contains the engineering analyses including failure trend 

analysis, component trends in time, failure characteristics and their causes, a 

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

and engineering insights from the various analyses. 

4.1 Failure Trend Analysis 

Appendix III gives data for trending MDP failures. MDP failure trends during 

the 1987-1995 period are illustrated in Figure 16. 

As stated 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, NPRDS and LER 

failure data was used for trending the 1987-1995 period. 

Failure trends of MDPs for the PWR and BWR RI systems during the 1987

1995 period were relatively constant, except for an upward peak in 1992 and 

1993 for PWRs and in 1993 for BWRs.

4.2 Component Trends In Time

Methodology 

The initial assumption made in this study is that the rate of failure events over 

time (A) is constant. Several methods were used to check this assumption to 

determine if any significant age-related increase in A occurred among-older 

plants. An increase in A due to aging could only occur if the following 

conditions were present: 

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

was increasing), and 

2. A was higher for the older plants; and 

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, AAw, equal to the total number of 

MDP failures (ESF and surveillance test) for the 1987-1995 period, divided by 

the cumulative number of MDP component-years of operation during the 

period. Failure data from the 1996-1998 period was not included since it was 

limited to ESF and sparse surveillance test data reported in LERs. 

The cumulative number of failures were plotted against the number of MDP 

component-years since the beginning of the study period (i.e., 1987) and 

compared with AAw This was done for PWRs and BWRs for combined plant 

age groups (all PWR and BWR plants) and individually for plant age groups 

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

component studies. There were 73 PWR plants and 36 BWR plants with 

MDPs. The following table defines the plant age groups and gives the 

number of PWR and BWR plants in each group:

C 04101184 and later 36 24 12

19
The assumption (i.e., the null hypothesis) that AA,. is constant during the 

study period for each plant age group and for the combined plant age groups 

was evaluated. The failure rates (,Ava) are the slope of the plots for each 

plant age group. Plant age groups were compared to determine whether 

there was any indication of plant aging (e.g., a higher slope for the older plant 

age groups than for the newer plant age groups). A statistical test for the null 

hypothesis is the Laplace test. For this test, L12 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 criterion 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 of the standard distribution). With a 

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

>+1.645), there may be aging. The formula for the U statistic is: 

U ==- up where n = no. of failures, TI = interval between failures in component-years, and 

L V"7'Mn T=Erl/n 

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

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

combined plant age groups.

Results

Appendix II provides tables applicable to component trends in time evaluations 

for MDPs. 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 MDP failures over time to the applicable 

average failure rate (AAvE) plots for PWRs and BWRs indicated the following: 

PWRs (see Figure 17) - For the PWR RI systems, a review of plant age groups 

did not show evidence of an increase in A 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 not rejected. The value of U at the 10-percent significance level was + 0.17 (very close to zero) and did not show any evidence of 

a nonconstant failure rate. 

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

also not rejected. The value of U at the 10-percent significance level 

was + 0.30 (also very close to zero) and did not show any evidence of 

a nonconstant failure rate. 

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

also not rejected. The value of U at the 10-percent significance level 

was - 0.85 and did not show 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. However, the AAw for B 

(0.019) was slightly higher than forA (0.017), and that both rates were 

slightly higher than for C (0.012). Therefore, there was no evidence that 

failure rates increased as a function of plant age. 

When the causes of PWR MDP assembly failures were reviewed, 

unknown causes accounted for 43%, followed by agelwear causes (27%) 

and maintenance/procedural deficiencies (16%)(see Figure 20). 

Therefore, agelwear mechanisms were not the predominant cause of 

failure.

21
BWRs (see Figure 18) - For the BWR RI system MDPs, the review of plant age 

groups did not show evidence of an increase in A for any of the plant age groups 

due to aging mechanisms. 

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

not rejected. The value of U at the 10-percent significance level was - 1.585 (close to -1.645 and decreasing), and did not show any 

evidence of a nonconstant failure rate. 

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

also not rejected. The value of U at the 10-percent significance level 

was + 0.97 (<+1.645) and did not show any evidence of a nonconstant 

failure rate. 

For plant age group C, the hypothesis was not rejected either. The 

value of U at the 10-percent significance level was + 0.29 (close to 

zero) 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. Plant age group A 

(0.010) was slightly lower than for.B (0.012) and C (0.012). Therefore, 

there was no evidence that failure rates increased as a function of plant 

age. 

When the causes of BWR MDP assembly failures were reviewed, 

age/wear (43%), unknown (26%), and maintenance/procedural 

deficiencies (20%) were found to be the most significant causes. 

Therefore, age/wear mechanisms were the predominant cause of MDP 

failures (see Figure 20).

4.3 Failure of Subcomponents and Their Causes

Methodology 

The MDP assembly failures and causes were identified on a subcomponent 

level in the NPRDS database. LER reported failures in the SCSS database 

and the LER narrative provided sufficient information to identify the failed 

subcomponents and causes and to group these failures using the NPRDS 

categories. The apportionments were done to obtain insights into the 

predominant subcomponent failures and their causes by reactor type (PWR 

and BWR). 

The subcomponents were also grouped by PWR and BWR and the causes of 

failure were calculated as percentages. The cause categories of failure used 

are similar to those defined in NPRDS. 

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

Agetwear (AW) Dirtlcontamination/corrosion (DC) 

Design deficiency (DD) Manufacturing defect (MF) 

Unknown (UK) Maintenancelprocedural deficiencies (MP) 

Out-of-adjustment (OA) Mechanical linkage (ML) 

Results 

Figure 19 shows the MDP subcomponent failure apportionment for the PWR 

and BWR RI systems. For both PWRs and BWRs, the evaluation of MDP 

subc6mponent failure patterns determined that circuit breaker failures 

accounted for greater than three-quarters of all MDP subcomponent failures. 

Pumps failures were less significant and motor failures were considered not 

significant (less than 10%). 

Failure causes for all MDP assemblies are illustrated in Figures 20 and 21. 

For the PWR RI systems, the causes were mainly due to unknown (43%), 

age/wear (27%),and maintenance/procedural deficiencies (16%). For the 

BWR RI systems, the causes were mainly due to agelwear (43%), unknown 

(26%), and maintenancelprocedural deficiencies (20%). 

For lack of a root cause analysis, failures to many MDP subcomponents, 

particularly circuit breakers, were attributed to unknown causes.

4.4 Related Issues - Information Notices

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

subcomponents included Generic Letters, Circulars, Bulletins, and Information 

Notices (INs). This review determined that only the 12 INs listed in Table B 

were directly applicable to MDP assemblies and their subcomponents during 

the 1987-1998 period. INs that identified system interactions with MDPs or 

potential MDP failures due to system alignment or procedures were excluded. 

The review of the listed INs did not identify any catastrophic failures 

associated with ESF demands or surveillance testing used in this study.

5. SUMMARY OF RESULTS

5.1 Failure Probabilities 

For the PWR and BWR RI systems, the MDP probability of failure on demand 

estimates were based on the failures and demands in the combined ESF and 

surveillance test data from SCSS and NPRDS data sources, except for the 

PWR residual heat removal and nuclear service water systems and the BWR 

residual heat removal system. For these exceptions the surveillance test data 

was used. The MDP probability of failure on demand estimates were 

consistent with the generic values from NUREGICR-4550, which was used as 

an input to NUREG-1 150, except that the value- for the BWR reactor building 

closed cooling water system was lower and the mean and upper bound 

values for the high pressure core spray system were higher. 

The yearly trend analysis for the MDP probability of failure on demand showed 

no trend for PWR and BWR RI systems, except for the PWR high pressure 

injection (HPI) system. The HPI system showed a slightly increasing trend 

through the 1987-1995 period, but this was evaluated as not significant. 

The MDP mean probabilities of failure on demand from plant-specific IPE studies 

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

,generally consistent with the results of this study and NUREGICR-4550. The 

IPE mean values for BWR RI systems were also consistent with the results of 

this study and NUREGICR-4550, except for the RHR and RBCC systems. Sixty 

percent of the IPE mean values for the BWR RHR system were higher than the 

RHR system value range estimated in this study. Most (approximately 89%) of 

the IPE mean values for the RBCC system were higher than the RBCC system 

value range estimated in this study. Although the higher values are not 

considered significant, this study does not support plant-specific system values 

when the mean values are lower than the system lower bounds values 

developed in this study. 

5.2 Engineering Insights 

The engineering insights gained from this study are as follows: 

• Failure trends for the PWR and BWR RI systems during the 1987-1995 

period were relatively constant, except for an upward peak in 1992 and 

1993 for PWRs and in 1993 for BWRs.

30
Failure rates, as a function of component-years, varied slightly among the 

PWR and BWR plant age groups (three groups, of approximately equal 

size, from older to newer plants by commercial operations date). For 

PWRs, the review of plant age groups did not show evidence of an 

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

mechanisms. For BWRs, the review of plant age groups did not show 

clear evidence of an increase in failure rates for any of the plant age 

groups due to aging mechanisms. 

The evaluation of MDP subcomponent failure patterns demonstrated that 

circuit breaker failures were significant contributors to MDP failures in both 

PWR and BWR RI systems (greater than 75%). 

Failure causes for MDP assemblies in PWR RI systems were mainly due. 

to unknown causes (43%) because a root cause analysis was generally 

not performed on the predominant failed subcomponent (circuit breaker). 

Age/wear and maintenance/procedural deficiencies together accounted 

for the bulk of the balance of failures (43%). For BWR RI systems, 

age/wear was the predominant cause (43%), while unknown causes and 

maintenance/procedural deficiencies together accounted for the bulk of 

the balance (46%).

NOTES: 

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

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

AFW, HPI, CCW, and CVCS 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. 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 

NSW and RHR systems. The surveillance test data (1987-1995) was used for estimating the 

probability of failure on demand for these systems. 

3. The 90% confidence Intervals (chl-square) are provided for Information. The Bayes 90% 

Intervals are used In this study for RI system estimated probability of failure on demand. 

4. Average standby failure rates (A, failures per component-hour), based on 1987-1995 failure data 

for the combined ESF and surveillance tests for the PWR RI systems, are provided for 

Information, as follows: 

AFW: A = 1.1E-6; A = 2.2E-6; Au = 3.2E-6.

NOTES: 

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

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

HPCS, LPCS, RBCC, and ESW 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. 

4. 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 

RHR system. The surveillance test data (1987-1995) was used for estimating the probability of 

failure on demand for these systems. 

6. 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. 

4. Average standby failure rates (A, failures per componenent-hour), based on 1987-1995 failure 

data for the combined ESF and surveillance tests for the BWR RI systems, are provided for 

Information, as follows:

10. SUPPLEMENTARY NOTES 

11. ABSTRACT o *ads a-hi) 

This report documents an analysis of the performance of safety-related motor-driven pump assembles (motor-driver, pump, and 

circuit breaker subcomponents) used in pressurized water reactor (PWR) and boiling water reactor (BWR) ilsk-important systems 

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-driven pump components on an industry basis and comparison of results with data used by 

plant-specific probabilistic risk assessments. The data used In this report was from the 1987-1995 period for engineering analysis. 

Failure probability estimates used combined engineered safety features data (1987-1998) and surveillance test data (1987-1995).
