This report describes the results of a project to improve the generic component failure database for theSavannah River Site (SRS). Additionally, guidelines were developed further for more,advanced applicationsof darabase values. A representative list of components and failure modes for SRS risk models was genetaedby reviewing existing safety analyses and component failure data bases and from suggestions from SRS “safety analysts. Then sources of data or failure rate estimates were identified and reviewed for applicability.A major source of information was the Nuclear Computerized Library for Assessing Reactor Reliability, orNUCLARR.’ This source includes an extensive collection of failure data and failure rate estimates forcommercial nuclear power plants. A recent Idaho National Engineering Laboratory report on failure datafrom the Idaho Chemical Processing Plant was also reviewed? From these and other recent sources, failuredata and failure rate estimates were collected for the components and failure modes of interest. For eachcomponent failure mode, this itiorrnation was aggregated to obtain a recommended generic failure ratedistribution (mean and error factor based on a Iognormal distribution). Results are,presented in Table 1 inthis report.

A major difference between W generic database and previous efforts is that this effort estimatesfailure rates based on actual data (failure evews) rather than on existing failure rate estimates. This effort wassuccessful in that over 75°/0of the results are now based on actual data. Also included is a section onguidelines for more advanced applications of failure rate data.

1. INTRODUCTION

As part of an overall effort to upgrade the methodologies for stiety analyses of nonreactornuclear facilities at the Savannah River Site (SRS), a new generic component ftilure database wasdeveloped. The project to update the SRS generic component ftilute database had several goals:

Provide information for various failure modes for each component, where possible. Anexample is to provide ftilure rates for valve ftilure to open/close upon demand and valvespurious operation, rather than just valve ftilure. Such ftilure mode information is oftennecessary for detailed fault tree models.

Base component ftilure rates on actual data (ftilure events) wherever possible.

Use the most up-to-date and applicable data sources available.

Provide a clear documentation trail for each component failure rates estimate, such thatothers can review the basis for each estimate.

The entire project was structured such that these goals could be accomplished. All of the goals weremet.

Based on a review of existing stiety analyses and component failure databases, and based onadditional input from SRS safely analysts, a comprehensive list of components and ftilure modeswas generated. The list is shown in Table 1. Approximately 500 component and ftilure modecombinations were identified. Given this list of components and failure modes, sources wereidentified that contained applicable failure data or failure rate estimates. A section on guidelines forthe use and applications of fhilure rate data is also included.

2. DATA SOURCES

Sources used to develop the SRS component generic database may contain actual failuredata or failure rate estimates. Also, sources containing failure data may vary in the quality or detailof the information. Therefore, three categories of sources were established:

Category 1- Sources with actual failure data obtained from a detailed review of failureevents (to ensure applicability to the failure mode being considered) and a detailed review ofcomponent populations and exposure duration’s (or demands). Such data include theplant-specific component ftilure data collected for probabilistic risk assessments (PRAs) orreliability studies. The NUCLARR1 database has 19 Category 1 sources, all from nuclearpower plants. For this project the Savannah River Site (SRS) reactor data were added. Thedata sources include the following:

Including these Category 1 sources increased the Category 1 data by nearly 20%.

Category 2- Sources with actual failure da@ but which have an added uncertainty in the datacompared with Category 1 sources. This added uncertainty can result from a less comprehensivesearch for actual failures, a more approximate method for determiningg component populations orexposure duration’s (or demands), or a less clear breakdown of failures into the failure modes ofconcern. NUCLARR has 10 Category 2 sources “inits database. For this project, an additional fiveCategory 2 sources were identified and used

NPRD-3S -By carefhlly reviewing failure mode information presented in tables in thisdocument, the failure data presented in NPRD-3 could be divided into the failure modes ofinterest for this project.

0REDA7 - Failure data iiom components in offshore oil drilling facilities are presented inthis report. In some cases judgment was needed to break down the data by ftilure mode.

WIN-330 - This document lists ftilure data obtained from the Department of Energy (DOE)Idaho Chemical Processing Plant. However, this document does not distinguish failuremodes, so some judgement was needed to break down the data by failure mode.

Tritium8 9 ‘d 10-These documents include ftilure data from a tritium handling facility at theLos A&& National Laboratory. Again, judgement was needed to break down the data byfailure mode.

LNG111- Failure data from liquid natural gas facili~ components are presented in thisdocument. Judgement was needed to break down the data by failure mode.

Addition of these five sources more than doubled the amount of data from Category 2 sources inNUCLAR.R

Category 3- Sources that list only ftilure rate estimates. Six representative sources wereused in this project. Many more such sources exit. The six were chosen to represent avariety of industries.

All of the sources used in this project are listed in Table 2.

3. AGGREGATION ROUTINES

As discussed in Section 2 of this report, sources of data were grouped into three categories,depending upon the type and quality of information presented. For a given component and ftiluremode, several sburces within a category might have failure tiormation. Also, a single source maycontain several sets of failure data. Therefore, aggregation routines are needed to combine theinformation from the different sources to obtain a representative result. Two different aggregationroutines were used: ,

1. Combining actual failure data (failures and component exposure hours orDemands) from different sources (used for Categories 1 and 2).

2. Combining failure rate estimates that also include error factor estimates (usedFor Category 3).

For Categories 1 and 2, the aggregation procedure is as follows*:

1. Compute Rand R2from source datai

Where &= number of failures from source i

Ti = component exposure time (h) from source i.

2. Match moments to obtain underlying normal distribution:

M = 2 in(R) -0.5 ln(RJ

S2= ln(RJ-21n(R).

3. Determine mean and error factor of lognonnal distributiorx

Mn = exp(lvl + S2/2)EF = exp(l.645 S)

where Mn =ean

EF = error factor (95th percentile/50th percentile).

For data involving demands rather than exposure hours, the same equations apply, bitWith Ti replaced by Di (number of demands from source i). If tie procedme described .above resulted in an error factor greater than 10, the error factor was chosen to be 10.

.-.....---. .-—-.—-. ..-— . .. . . -..—— — —— --- .-- —-.. ——-.. .. ..,--. -


Three special cases may arise when aggregating actual failure daa such that the above routine doesnot work.

The first is the case where only one data set is available (number of ftilures and number of hours ordemands). In this case a Bayesian update of a non-informative prior was used to determine the meanEstimate 3!

Mn = (2n + 1)/(2T) (for time-related data)

Mn = (2n + 1)/(2D + 2) (for demand-related data).

In both cases, an error factor of 10 was used. The error factor of 10 w& chosen by examining theaggregated results in Tables 3 and 4 and calculating an average error factor.

The second special case occurs when all of the data sources involve zero or one ftilure. Inthis case, the data were combined (failures added and exposure hours or demands added) to obtainone data set which was then treated similarly to the case just described.

Finally, the third case arises when S2is less than zero. This case was treated thesame as the second special case.

For Category 3, the aggregation routine is the followin<7:

1 Determine variance for each source:

s?= [h@Fi)fl .645]2-

2. Determine natural logarithm of median for each source:

(hi- ln(M@ - S~/2

where ~i natural logarithm of median.

3. Determine average of source variances:

Sav:= (z s:)/4

where ~ = number of sources.

4. Determine average of natural logarithms of medians:

6.) = [X((lli/si)@(l/si)]]

Mn = exp(o + 0.5 S2)

EF = exp(l.645 S)

Where S = largerof Saveor So

Some of the Category 3 sources do not list error factors. In such cases, an error factor (3,5,10, or 30) was assumed based on an average of error factors from the other sources. If no sourceslisted an error factor, then 10 was used. Also, if the aggregation resulted in an error factor greaterthan 30, then the error factor was assumed to be 30. Finally, if a single source listed several fbilurerate estimates, then the estimates for that source were aggregated using the procedure describedabove. Then the result for that source was combined with the other sources.

Because a goal of this project was to base component ftilure rate estimates on actual failuredata (contained in Categories 1 and 2) wherever possible, and because the quality of data inCategory 1 sources is expected to be better than that for Category 2, aggregations were pefiormedonly within categories. Results from each category aggregation were not combined to obtain anoverall result.

4. DATA SEARCH

Results of the search for component failure tiormation are sunimarized in Tables 3 through5. Tables 3a through 3f present the Category 1 data by component failure mode, and type ofsystem. The NUCLARR1 column in Tables 3a through 3f actually represents the aggregation-of allof the Category 1 sources in FKJCLARR. Tables 4a through 4f present the Category 2 results, andTables 5a through 5t the Category 3 results. Also presented in each table are the aggregated results(mean failure rate and error factor).

5. RECOMMENDED RESULTS

Recommended component generic ftilure rates are presented in Tables la through lf. Therecommended results were obtained from the Category 1 aggregation, if such data existed. If not,then the Category 2 results were used. Finally, if neither Category 1 nor Category 2 itiormationwere available, then the Category 3 results were used. Also, because the product of this effort is ageneric database, the mean frequencies were rounded off to 1,3, or 5 times the appropriate power of10. Error factors obtained from the aggregation process were rounded off to 3, 5, or 10. Tables 6athrough 6f contain more detailed notes concerning the selections of recommended ftilure rates.

A review of Tables 6a through 6f indicates that approximately 75% of the recommendedfailure rate estimates are based on actual failures from nuclear power plants or other types offacilities. The remaining 25% of the estimates had to be generated from sources listing only ftilurerates.

It should be noted that failure data may be reflective of a pa.xticular application orenvironment. In cases where data is limited to sources of specialized application or operatingenvironments, it may be appropriate to modi@ the recommended mean to account for alternativeconditions. In all cases, engineering judgment should be used in the application of generic data.

Also listed in Tables la through If are identifiers such as PIP-LE-W for each of thesystern/component/fhilure mode ftilure rate distributions. In the identifier, the first three letters, PIP,indicate the type of component, which is a pipe. The second set of letters, LE, indicates the ftiluremode, which is external leakage. The final letter, W, indicates the type of system, which is a watersystem. Tables 7, 8, and 9 list the codes used for components, ftilure modes, and processing fluids.Parts of this naming scheme were obtained from the report Review and Development of CommonNomenclature for Naming and Labeling Schemes for Probabilistic Risk Assessmen~8. However, insome cases the naming schemes for components and failure modes, recommended as standardpractice in Reference 38, were changed ~o allow for a more consistent approach. Also, manyadditional components had to be added.

6. APPLICATION GUIDELINES

Guidelines on application and use of failure rate dati

I. Time Dependent Failure Rate ( A )

For a normal operating facility component failure is essentially a random process and thefailure rate k, is treated as a constant. However, in the total life cycle of the facility, Z takes updifferent values for its three distinct phases (the famous ‘Bathtub’ profile). For the initial ‘infantmortality’ phase, A decreases with time, then remains constant during the normal steady stateoperation phase and finally increases with time in the ‘aging’ phase. The initial phase is of minimalimportance in risk studies, but the ‘aging’ phase is relevant for many older facilities like SRS.Failure probabilities in the random steady state phase is adequately predicted by the Exponentialmodel with constant h. However, ftilures in the ‘aging’ process are better estimated by theWeibull distribution

P(t) =1- e** -( t/q )** ~, where, q is the scale or reliability parameter (- l/X.), and~ is the shape parameter, 1< ~ <4 (for ‘aging’ phase).

As a simplification, studies indicate that exponential approximation with a ‘modified’ 1 (fixed at 30% to 50’%higher than the ‘nominal’ A) appears to yield reasonably good resultsespecially in the time range of 1 to 2.5 MTBF (Mean Time Between Failure= 1/2.). In the timeperiod beyond 3 MTBF, Weibull distribution is recommended for failure probability determination.

Note: Sensitivity studies performed with Exponential model (with ‘modified’ k = 1.3 to 1.5times ‘nominal’X) and Weibull model (with 1< ~ Q, range of interest for most facilities likeSRS), document the validity of the above assertion.

II. Failure on demand ( X~) and Conversion Factors to Hourly Failure Rate (1)

Component ftilure rates are sometimes specified in per demand (typically, fails to start oroperate on demand, eg. diesel generator) rather than per time period (hour etc.). However, anMTBF value for components is required for Risk/ RAMI analyses. The MTBF can beexpressed as the reciprocal of the hourly ftilure rate k, ie. MTBF = l/A. But a demandfailure probability &must first be changed to an hourly failure rate h before it can beconverted to MTBF. This can be done by assuming that the time period between successiveequipment demands is one day and then dividing Xdby 24 hours. This results in a hourlyfailure rate that can be converted to MTBF as noted earlier. However for many standbyequipments the period between successive demands ranges from 1 to 3“months or sometimeseven to a year or more. Thus the assumption of daily demand period is quite conservative formany applications. . .

9


Based on engineering judgement and expert opinion the following conversion factors arerecommended for use with standby equipment with varying demand frequencies:

.

Observed Demand Frequency Recommended Frequency for Analysis1 or more per day Hourly, 1 per hour

linlto3months Daily, 1 per 24 hours

1 or 2 per year Weekly, 1 per 7*24=168 hours

Note: Demands on standby equipments are triggered by some anticipated failure events ( eg.power supply failure for diesel generator demands). The above recommendation is based onan uncertainty factor of -25 (ie., EF=5 ) which is considered a reasonable spread for mostanticipated events. When no reliable observed data is available for a facility, “anuncertaintyfactor of -100 (ie., EF=1O) may be used with the assumed frequency for analysis. Forexample, for an assumed frequency of 3 per year, the recommended frequency would be(3/365)*100 = 1 per day (i.e.,daily).

III. Credits for Maintenance Programs

Improvements in component reliability can be obtained with reduction in un-scheduled /un-anticipated component repair/ ftilure through improved maintenance programs.

a) Preventive Maintenance (PM)Under this maintenance program components are replaced or repaired to their originalperformance level every ~ years, instead of letting them remain in place until failure.Replacement of components ahead of their MTBF improves reliability (ie. theprobability that an item will operate without failure over some specified mission time)which can be expressed as follows:

Reliability R(t) = e**-M for t< T, no~al reliability equation= e**-~*T for t 2 T, where T is the replacement time interval

b) Predictive/Precision Maintenance ( PdM/Pc~PdM involves monitoring of SSC’Sthrough non-intrusive tests/ inspections to detectcomponent degradation and to identi$ potential problems and is a valuable tool inpreventing ftilure. Some”commonly used PdM technologies are:

Vibration Monitoring and Diagnostics,Infhred Thermography,Lubricating oil analysis, Ferrography and Grease analysis, -Acoustic/ Ultra-sonic tests,Radio Frequency monitoring, Polarization Index etc. “ “

10


These technologies have been credited to significantly reduce component failure ratesand improve reliability here at SRS as well as at other facilities.

Precision Maintenance (PcM) program at SRS utilizes Root cause Analysis technique toall significant incidents to better define and apply PdM technologies to suit specificcomponents and applications.

A 50% to 75’% reduction in component failure rates has been observed in system/facilities with successfid PdM/ PcM program. This corresponds to a 4 to 2 increase inMTBF.

Iv. Uncertainty and Error Factor (EF)

The choice of the value of Error Factor (EF) is highly significant due to its influenceon the value of the Mean which is the most commonly used parameter in risk analysis.The maximum value of the Error Factor (EF) applicable to ftilure rates in this document hasbeen limited to 10. This coxesponds to a data spread QK95’Yo/X05’XO)of 100 with a Meanbounding 76% of the population at 2.6 times the Median (X50%). A higher EF of 30.(used “in earlier version of the document) would make the data spread -1000 with the Meanbounding only 80V0(a marginal improvement of 4% from the 76%) of population at aconsiderably higher value of 8.3 times the Median value.

An EF value in excess of 10 would normally reflect poor samples with no well-defineddistribution. Choosing a higher median value coupled with a smalIer EF might be a betterapproach for such sample distributions than a lower median value with a larger and lessmeaningful EF. The EF value of 30 in the original issue of the document (primarily for therupture mode of ftilure) was arbitrarily chosen for conservatism with no hard data tobackup. In fact, even for the rupture failures, the observed EF’s in the data tables were inmost cases equal to or below 10. A review of some independent PRA reports of nuclearplants ( eg., Oconee, Seabrook etc.) also indicated that in less than 1% of cases EF exceeded10. Hence an upper limit of 10 for EF is deemed more reasonable.

v. Use of only SRS HistoricalData (with no additionaldata sourceavailatde)

When using sorts of events from SRS incident databank as the only source for computingcomponent failure rates/ fi’equencies, the following table (based on Ref. 27,40) provides the ~appropri~ multiplier R to obtain either the 95% upper-bound failure rates (AJ for thepreferred conildence limit ( based on clm-sical conlldence interval property) or the 50%median failure rates ~

h=(Rgszx N)/TorD where N= number of observed faihues, and T, D

&=(RmxN)/TorD indicate time period or demands “

N Rg5% Rswo 3* 0.69 *1 4.5 1.682 3 1.34

3-6 2.1 1.17-1o 1.7 1.0711-30 1.4 1.03

31-100 1.1 1.01

* This number replaces the numerator (R x N ) in the corresponding equation above.

It is recommendedto use 95% coni%lence limit values ( column 2) for conservative analysisof acute events and 50% limits ( column 3) for realistic analysis of chronic events.

Not& This methodis suitable when historical data provides only the number of occurrencesand time intends of the events and not any further detailed information.

Bayesian Update

Using a Bayesian Update technique, additional available generic data on componentfailures(as found in lEEB-Std-500, Ref.-3l) can be utilhd together with SRS incidentdatabank (or any other facility or site-specific) information to develop more realistic failurerates typical of a larger industrial population. Unlike the simpler classical approachmentioned earlier for single data source, the Bayesianupdatehas the capabiity to combine“a prior” experiencewith posterior data to develop “posterio? probabilitybased on Bayestheoremwhich states thaG

PosteriorProbabil@ is proportionalto Prior probability( from genericdata) timesLikelihoodfiction (from Site specific data).

Appendix-B showsthe outline of BayesianUpdate model and someexamples in MicrosoftEXCELspreadsheetformat. .

This would the be.prefemed.methodfor data compilationand analysis to be used for full-scopePRA’s or formalSafety analysisreports.

VIL CommonCausefaihue - ~ factor

Dependentfailures such as commoncause failures at the systemslevel are treated eitherexplicitlyby meansof identifjhg causesof dependentfailure and by incorporatingthemexplicitlyin the systemsor event sequencemodels,or implicitlyby using certain parametersto accountfor their contributionto the systems’unavailability.Examplesof the fmt type aresharingof commoncomponents,fires, floods etc. The discussionhere deals with the secondtype, which includesfailuresthat are not coveredin the fmt typebut are occasionallynon- “random,that is, dependent.Examplesare designerrors, constructionerrors, proceduredeficiencies,and unforeseenenvironmentalvariationsand certain types of human errorduring test and maintenance,etc. The parametricmodel used to quantifythe effect of thissecondcategoryis knownas the &factor method.The parameter~ is defined as the ffactionof the total componentfailure rate attributableto commoncause failures

~ = itd (k + M ) = WA where k= component’sdependentfailure rateXi=component’sindependentfailure rateA = Component’stotal failure rate

So that, k= ~L and M= (1-~)k and 0S ~ S 1

Some commonlyused @- factor distributions”are shown in the table below (Ref. 39):
