EQUIPMENT FRAGILITY DATA BASE

ABSTRACT

Part of the effort of the Seismic Safety Margins Research Program (SSMRP)
has been directed at generating a fragility data base for equipment used in
control and safety systems in commercial nuclear power plants. Component
fragility data have been compiled in various forms, depending on their
content, intended use, and level of reduction. The data are stored in a
relational data base on the LLNL CDC 7600 computers; this provides easy
accessibility for LLNL computer users. This report describes the present
structure of the data base and presents its contents through the use of
tables. This report is a revision of an earlier one of the same name and
numbers (NUREG/CR-2680) and (UCRL-53038). Additional data have been included
and the presentation has been revised to enhance its usability.

The fragility parameter for each is spectral acceleration (g).

The failure mode description of the first two sets clearly calls for them
to be grouped together as one mode.

The next four (134-137) are similar in failure mode, each indicating a
functional problem, and in addition 134 and 135 are probably the same failure
mode. Therefore, 134 through 137 will contribute to the same failure but a
further subgrouping of 134 and 135 is indicated.

The last four sets all indicate structural failure, and in addition 139
and 140 are for the same location on the valve. Therefore, 138 through 141
will contribute to the same failure mode and further subgrouping of 139 and
140 is indicated. The following summarizes the grouping to be used:

OPNO Group Subgroup Failure Mode
132 1 1 Leakage

133 1 1 Leakage

134 2 1 Functional Failure
135 2 1 Functional Failure
136 2 2 Functional Failure
137 2 3 Functional Failure
138 3 1 Structural Failure
139 3 2 Structural Failure
140 3 2 Structural Failure
141 3 3 Structural Failure

Applying the analysis described in Section 3.1 leads to the following 1og-
normal results.

Individual Mode Total
ow hk hg
132 12.1 0.159 10.0 0.329
133 8.2 0.203 8.5 0.339
134 15.3 0.201
135 7.3 0.142 15.9 0.620
136 28.2 0.476
137 12.2 0.120.

139 15.3 0.201 21.6 0.714
140 17.3 0.275
141 46.4 0.635

Thus, for this payticular grouping of data, a resulting single distribution
for fragility of m= 8.5 g, 6 = 0.339 is obtained.


1.0 INTRODUCTION

One of the primary objectives of the SSMRP is to develop both a
methodology and mathematical models that realistically predict the probability
of radioactive releases from seismically induced events in nuclear power
plants. The Fragilities Development Project! was established to help meet
this objective. Research in the project centers on the development of power
plant structure and component fragility in probabilistic terms. A complete
Presentation of the sources of data and methodology used by the SSMKP for
fragilities development is included in Ref. 1.

Approximately 50 generic categories of mechanical and electrical
components were originally identified for this purpose. Of this number, 37
were chosen for subsequent fragility development. The fragilities developed
for these categories are based on site-specific data and design reports from
the Zion Nuclear Power Plant, the U.S. Army Corps of Engineers Safeguard
Program, and the results of an extensive expert opinion survey conducted by
the SSMRP. This data base consists of a variety of information, all related
in some way to the development of the fragilities for these categories of
components.

The data base was structured on LLNL's CDC 7600 computers through the use
of the FRAMIS data base management system, and while access to the data is
most conveniently accomplished by using FAMIS, it can also be accomplished
with the tables in this report. FRAMIS is documented in Refs. 2 and 3.

Some of the data have been grouped into tables that were structured for
convenience in the fragility data reduction process. Other tables were
structured simply to allow convenient storage of information. FRAMIS allows
easy regrouping of data into virtually any format that the user may find
useful. This data base is continuing to expand as new data are collected.

EXECUTIVE SUMMARY

This report describes a relational data base, which consists of seismic
fragility descriptions for nuclear power plant equipment and data from which
many of the fragilities were developed. The fragilities stem primarily from
three sources:

1. Design analysis reports from manufacturers of components for the Zion
Nuclear Power Plant.

2. Experimental data obtained from the results of component
manufacturer's qualification tests, failure data testing by
independent laboratories, and data obtained from the U.S. Army Corps
of Engineers SAFEGUARD Subsystem Hardness Assurance Program.

3. The results of an extensive expert opinion survey conducted by the
Seismic Safety Margins Research Program (SSMRP).

The basic data resulting from the expert opinion survey, including 10th,
50th, and 90th percentile estimates of probability of failure for many
categories of equipment and a variety of failure modes are included. Also
included are the results of combining both individual opinions within a
failure mode and various failure modes within categories. The statistical
methods used in making these combinations are discussed.

Since the process of adding to the data base and statistically combining
these data is continuing, the listings of data included represent the status
of the contents of the data base at this report date and may be upgraded by
new data at any time.

4.0 LOAD SCALE FACTORS FOR PIPING ELEMENTS

The development of fragilities for the piping systems at Zion presented a
different kind of problem than other categories of equipment, since fragility
descriptions were needed for virtually every conceivable combination of piping
elements. The approach taken was to avoid developing separate fragilities for
each combination by relating individual pipe element fragilities to a master
pipe element fragility by means of a load scale factor, Fos defined as

F = Capacity of reference pipe element
Pp Capacity of pipe element under consideration

These factors were computed for several sizes and schedules of pipe
elements, including straight pipe, butt welds, elbows, miter joints, and
branch connections. The development of the load scale factors is discussed in
detail in Ref. 4. The data base contains the resulting load scale factors
together with the related piping element parameters. They can be found in
this report in tables in Section 6.2.


B. CATEGORY

Table CATEGORY relates the descriptions of the generic categories of
components to the numbers used to identify data for these categories. It
consists of three columns of data as follows:

Column No. Column name Type Contents

1 CATNO Floating A floating point number unique to
this particular description (Note:
CATNO is a subgrouping of CAT.)

2 CAT Integer An integer number unique to a class
of generic components.

3 DES Character The description of the generic
category or specific component
represented uniquely by CATNO and
generically by CAT.

Figure 1 shows the results of combining the groupings of expert opinion
data to result in one fragility curve for the functional failure mode. The
influence of the high weight factor assigned to OPNO 136 can be seen in the
tendency of the result toward higher fragility levels.

Figure 2 shows the results of combining the three failure modes to result
in one fragility curve for the category. Here the mode of lowest fragility
dominates the result. This will be true in every case of combining modes
since the result is computed by the union of the individual modes.

Other groupings might be considered than the preceding ones. For
example, leakage might not be considered a failure mode of concern, and in
that case OPNO's 132 and 133 would not be used. Data from sources other than
expert opinion can be included in the groupings by first determining from the
cumulative distribution function the 10th, 50th and 90th percentile values of
spectral acceleration (or appropriate parameter), assigning a weight factor,
and then treating the data in the same manner as expert opinion.

G.  GRPRES

Table GRPRES contains the lognormal results for each failure mode in each

generic category along with other pertinent information. It consists of seven
columns as follows:

Column No. Column_name Type Contents
1 CATNO Floating A floating point number unique to a

particular description of generic
category or component descriptions
(see Table CATEGORY).

2 DES Character The description of the generic
category or specific component (see
Table CATEGORY).

3 GRPNO Character An identifying code unique to a
particular set of data for a
particular failure mode (see Table

GRPMODE ) .

4 MEDIAN Floating The median of the data assuming
lognormal distribution.

5 BETA Floating The standard deviation of the natural
logs of the data.

6 PARAM Character The fragility parameter.

7 MODE Character A description of the failure mode.

5.0 SUMMARY OF FRAGILITIES

Section 6.0 of this report deals with the details of the data base
structure and content. The results of the various groups of data tend to be
obscurred by the number and details of the individual data sets, and since the
results of the groupings may be the only material of interest to some readers,
they have been extracted and are presented in this section. The following
tables are computer listings produced from the contents of the data base
through the use of the relational capabilities of the FRAMIS data base
manager. Each table represents one category of equipment and each set of
results consists of the lognormal distribution parameters (median and beta),
the failure mode description, associated notes, and group identifier that can
be used to obtain further information from the data base tables presented in
Section 6.2.

2.0 DATA SOURCES

For various reasons, actual fragility data for mechanical and electrical
components are very scarce. Consequently, the SSMRP conducted an extensive
expert opinion survey that yielded probabilistic information for several of
the component categories. In addition, data and design reports from the Zion
Nuclear Power Plant and data from the U.S. Army Corps of Engineers Safeguard
Program were used.

2.1 EXPERT OPINION SOURCES

Approximately 50 generic component categories were identified for
fragility determination. Experts were asked to identify modes of failure and
estimate 10th, 50th, and 90th percentile values for component strength at
failure by these modes as a function of an appropriate fragility parameter
(usually spectral acceleration). Each set of opinion data was evaluated using
several criteria, including source (i.e., manufacturer, test laboratory,
Professor, etc.), basis (i.e., test, analysis, etc.), and the expert's own
evaluation of level of his expertise. Weighting factors reflecting the degree
of confidence in the experts' opinions were then applied to each set of
estimates.

Thus, for a particular generic category of component and a particular
failure mode, one set of data consists of one expert opinion of the 10th,
50th, and 90th percentile values of strength at failure and a subjective
weighting factor.

The information obtained in the survey and the results of various levels
of reduction of the data are included in this data base.

2.2 ANALYSIS AND TEST DATA SOURCES

Data and design reports from the Zion Nuclear Power Plant and data from
the U.S. Army Corps of Engineers Safeguard Program were compiled and reduced
for the SSMRP by Structural Mechanics Associates (SMA).4 Selected data from
Ref. 4 are included in this data base. Modifications of these data (as
described in Section 3.2 of this report) are also included.

3.3 EXAMPLE OF COMBINING DATA

To illustrate the procedure used in combining data from several sources
to develop a single fragility, consider, for example, the category of small
miscellaneous valves (Category 18). There are 15 sets of expert opinion data
for Category 18. (OPNO 132 through OPNO 146 in the data base table OPINION)*
The first 10 sets will suffice to illustrate the procedure. A portion of the
data for these opinions follows:

If data for more than one failure mode is available for analysis, the

fragilities of the individual modes are combined to yield the union of these
modes, i.e.,

Frota, = [1 - (1 - Fy) (1 - Fo)...(1 - Fy].

The application of these statistical methods to the expert opinion data
was accomplished through the use of the Fortran program, FRAGSTAT, which is
documented in Ref. 6.

3.2 OTHER ANALYSIS

Reference 4 contains fragilities with lognormal distribution only. For
consistency and comparison purposes, it was desirable to have both normal and
lognormal data; therefore, a procedure for fitting the lognormal data to
result in a suitable normal distribution was needed. The following criteria
were used:

a. The statistical mean of the normal distribution was assumed to be the
same as the median of the lognormal distributions, i.e. p=m.

b. The standard deviation of the normal distribution was assumed to be

6.0 DATA BASE DESCRIPTION

In its current structure, the data base consists of 12 tables. Some of
the data have been grouped into tables that were structured for convenience in
the fragility data reduction process. Others were structured to allow
convenient storage of information. The data base was structured on LLNL's CDC
7600 conmputers through the use of the FRAMIS data base management system, and
while access to the data is most conveniently accomplished through FRAMIS, it
can be accomplished with the tables in this report as illustrated below.

6.1 RELATIONAL STRUCTURE

Each of the 12 tables contains not only lists of data, but also entities
that allow relationships to be constructed between tables. For example, many
of the tables contain an appropriate category number along with each set of
data. This allows relationships to be constructed between all of the tables
that contain category numbers. These relationships can be used to build new
tables representing compilations or subsets of the other tables. It is also
possible to relate data from tables that do not contain common entities if an
intermediate table containing an entity common to both is available. For
example, the fragilities in table RESULTS* can be related to the expert
opinions in table OPINION by first relating RESULTS to GRPMODE using entity
RESNO, then relating GRPMODE to GRPDEF using the entity GRPNO, and finally
relating GRPDEF to OPINION using the entity OPNO. Applying this procedure to
RESOIA tthe first entry in table RESULTS) shows that three expert opinions
(and two calculated fragilities) were used in the development of RESOIA. The
10th, 50th, and 90th percentile opinions (along with other information) for
each can be found in table OPINION using the pertinent value of OPNO.
Relational operations such as these are quickly and easily accomplished using
FRAMIS.

*See Section 6.2 for descriptions and contents of individual tables.

3.0 DATA ANALYSIS
3.1 EXPERT OPINION ANALYSIS

It was assumed that a single fragility curve of normal or lognormal
distribution can approximately represent each generic component for a
particular failure mode. Since the various sets of expert opinion data could
be based on quite different components (because of size, manufacturing
techniques, design, etc.) within a single generic category, it was necessary
to provide for subgrouping of similar components within a category for each
mode.* For-each failure mode, the model for the qth percentile estimate
provided by the jth expert in the ith group is:

Xijg = ut Zgo + Ti + Eig >

isl,...,1 ,

x
Gt ees Nes GN

i? =N

i >
q = 10, 50, 90 indicating 10th, 50th, and 90th percentile estimates

where
lb o are the mean and standard deviations to be estimated.

T. is the deviation of qth percentile for ith group from overall
qth percentile (y+ 240) The T,'s are assumed to be
independent, identically distributed (11D) random variables with
zero mean and standard deviation, ore

Fijq is the variation in estimate of qth percentile given by jth
expert in ith group. Ei jq'S are assumed to be IID random
variables with zero mean and standard deviation, Og

Z is the value of the standardized normal cumulative distribution
function at the qth percentile.

*The statistical analysis methods used were selected and developed for this
application by R. W. Mensing and L. L. George. A more complete presentation
of the methods can be found in Ref. 5.


F. GRPNOTES

Table GRPNOTES contains qualifying comments pertinent to the various
groupings of data in GRPMODE. Information such as predominant frequencies and

specific equipment identification is included here. It consists of four
columns of data as follows:

Column No. Column name Type Contents

1 CATNO Floating A floating point number unique to a
particular description of generic
category or component description
(see Table CATEGORY).

2 GRPNO Character An identifying code unique to a
particular set of data for a
particular failure mode (see Table

GRPMODE ) .

3 LINE Integer A line number used for sorting and
editing.

4 NOTE Character Qualifying comments.

K. RESULTS

Table RESULTS contains the descriptions of the fragility data for generic
categories which result from certain groupings and subsequent reduction of

expert opinions and other data as computed by program FRAGSTAT. It consists
of eight columns of data as follows:

Column No. Column_name Type Contents
1 RESNO Character An identifying code unique to this

particular set of data.

2 CATNO Floating A floating point number unique to a
particular description of generic
category or component description
(see Table CATEGORY).

3 NMEAN Floating The statistical mean of the data
assuming normal distribution.

4 NSIGMA Floating The standard deviation of the data
assuming normal distribution.

5 LNMEAN Floating The statistical mean of the natural

logs of the data (i.e., assuming
lognormal distribution).

6 LNSIGMA Floating The standard deviation of the natural
logs of the data (i.e., assuming
lognormal distribution}.

7 MEDIAN Floating The median of the data assuming
lognormal distributions.

8 BETA Floating Same as LNSIGMA, repeated for
convenience in data extraction.
