FOREWORD

Probabilistic safety assessments (PSAs) are increasingly used for safety evaluation of researchreactors. PSA methodology and approaches for research reactors are in general similar to those usedfor power reactors. However, there are some significant differences. The main differences arerelated to the set of data to be used for quantifying the models.

As component reliability data for research reactors was not available in 1988, the IAEA initiateda co-ordinated research programme on data acquisition for research reactors. The aim of theprogramme was to develop rules and procedures for data collection (published as IAEA-TECDOC-636) and to conduct a data collection exercise on thirteen reactor facilities in ten participatingcountries.

The programme lasted for four years. The data collection exercise resulted in a databasecontaining reliability parameters for more than one thousand research reactor components. All thedata is based on the operating experience of participating reactors. The database was compiled duringthe final research co-ordination meeting held in Chalk River, Canada, in 1993.

The report was written by contributors from Austria, Canada and Switzerland and theproduction was co-ordinated by B. Tomic of the Safety Assessment Section of the Division of NuclearSafety. It includes data supplied by all the participants in the co-ordinated research programme.

1. INTRODUCTION

Information on reliability data for research reactor components was not readily available in theliterature in 1988. Similar information for power reactors is widely available for most power reactortypes, either on a commercial basis or from open literature sources [1-3]. Component reliability datasources for power reactors should provide the best alternative source of relevant data, in the absenceof either site-specific or generic research reactor data. The use of component reliability data forpower reactors, as an alternative to site-specific or generic research reactor data, does however havetwo basic disadvantages. Firstly, design and operational differences in many power reactorcomponents make comparisons difficult. The result is increased uncertainty in the application of ageneric reliability data source for power reactors to a specific research reactor application due todifferences in component type, size and application. Secondly, there are numerous research reactorcomponents that have no counterpart in power reactors.

To overcome the problem of data availability, the IAEA initiated a Co-ordinated ResearchProgramme (CRP) on Data Acquisition for Probabilistic Safety Analysis (PSA) Studies for ResearchReactors, aimed at providing the necessary generic component reliability database. The database,used by most CRP participants, was generated using the DES Data Entry System [4]. The CRPparticipant from ANSTO developed this system for use in conjunction with the data collectionprocess. DES was made available to other participants for data collection and is available from theIAEA for use as a reliability database. The report provides the user with the generic componentreliability database in a summarized spreadsheet format.

While this report focuses primarily on the needs of research reactor PSA, the genericcomponent database also provides a useful reference source of reliability data for other researchreactor applications. For example, typical applications would be the comparison of generic datasources for other research reactor types for the purposes of producing annual reactor operating reviewreports, or for updating reactor safety analysis reports. This type of comparison may assist inproviding useful information about both systems and component operation, in light of internationalexperience with similar research reactor types and equipment. For example, fuel failure rate data orregulating system failure rate comparisons could provide valuable input into research reactorupgrades/deterministic safety analysis programmes in order to supplement the decision making processfor potential design and/or operational changes.

Ideally, failure data used for safety and reliability analyses should be based on site-specific data.However, the production of accurate site-specific data requires the expenditure of considerableresources to develop and maintain an extensive database. The collection of database sourceinformation from the field — i.e. from reactor maintenance and/or operations reports — requires asystematic approach and an ongoing commitment, if the information is to be processed efficiently andif it is to be kept up to date. In addition to the need for operational and maintenance staff to provideraw data input, a software system and analytical personnel to process the raw data are also required.The data processing primarily produces component-reliability-parameter statistics and trend analysisdata. The reliability parameter data is often formatted so that information can interface directly withPSA studies. For example, component failure rate data may be linked to a PSA-specific basic eventlabelling format. The use of generic data by itself will not provide an adequate data source to aid intrend analysis of site-specific system equipment. Generic data can still, however, indicate whetherthere may be site-specific features or site-specific equipment problems that may be considerablydifferent from that which might be predicted from international generic sources of other researchreactors. The component reliability data in this report is applicable across a broad range of researchreactor types and sizes.

1.1. BACKGROUND

During 1986-1988 the IAEA undertook a Co-ordinated Research Programme (CRP) on PSAfor research reactors which helped to promote and foster an international exchange of information

between national institutes and universities on the subject [5, 6]. During this period, extensivesystematic PSA studies on research reactors were also being both contemplated for the first time andinitiated. The need for development of a research reactor component reliability database wasidentified from the research reactor PSA CRP work. This resulted in the setting up of the researchreactor data acquisition CRP. The application of PSA and the subsequent relevant databasedevelopment on research reactors followed similar developments for power reactors [1].

The current document was prepared using the framework of the data acquisition CRP. It isbased on the first meeting of the CRP held in Vienna in October 1989. A second meeting was heldin Beijing, China, in October 1990 and the final meeting was held in Chalk River, Canada in July1993. The report was completed in Vienna in December 1993. All members of the CRP contributedcomponent reliability data to the final database.

The CRP project officer was B. Tomic from the IAEA's Safety Assessment Section of theDivision of Nuclear Safety. Following the Beijing meeting, IAEA-TECDOC-636 was produced [7].This document provided the definition of terms to be used in the component data collection, derivedspecifically to cover research reactors. It also contains all the definitions necessary to classifyresearch reactor equipment, and to identify and group individual component boundary and componentfailure type definitions. Relevant reliability parameters are also defined and the method of calculationis shown in Ref. [7]. The various definitions are not repeated in the current report since Ref. [7] isintended to be a supporting document for the user of the database. An updated version of thecomponent group listing, the breakdown of component groups into component types, and theassociated coding is provided in Tables I and II. The failure mode code definitions of Ref. [7] arelisted in Table III.

1.2. PURPOSE

The purpose of this document is to supplement the information in Ref. [7] and to providereference generic component-reliability information for a variety of research reactor types. As notedin Section 2 and Table IV, component data accumulated over many years is in the database. It isexpected that the report should provide representative data which will remain valid for a number ofyears. The database provides component failure rates on a time and/or demand related basisaccording to the operational modes of the components.

No update of the database is presently planned. As a result of the implementation of datacollection systems in the research reactors represented in these studies, updating of data fromindividual facilities could be made available by the contributing research reactor facilities themselves.

As noted in Section 1.1, the report does not include a detailed discussion of informationregarding component classification and reliability parameter definitions, which is provided in Ref. [7].The report does provide some insights and discussions regarding the practicalities of the datacollection process and some guidelines for database usage.

2. REACTOR FACILITIES AND DATA COLLECTION METHOD

A total of 12 research reactors from 9 participating countries are represented within the CRP.Failure data on components have been submitted from each of these facilities. The data collectionperiod varied according to the facility, ranging from 2 to 28 years. Reactor-power ratings variedfrom 100 kW(th) to 135 MW(th). The number of components monitored varied from fewer than 20to about 10 000 per facility. Essentially all participants used component definitions from Ref. [7].The raw data sources were reactor log books, maintenance records and other documented operationalexperience. A compilation of the various general features of the reactor facility types and data issummarized in Table IV.

At the start of this programme no formal system for recording component reliability data wasin place in most facilities. After 1986 the initiation of PSA studies at most of these facilities providedan impetus for the development of a component reliability database. The database systems in thecontributing facilities are subsequently being maintained on a continuing basis for the purpose of long-term trend and equipment monitoring.

As noted in Section 1, the DES data entry system [4], was used by a number of participants toinput and record raw data. The component database for this report has been compiled from the DESoutput information provided by the participants. It is represented in an easy-to-use spreadsheet formatin Table VII. A description of the procedure for extracting reliability data from Table VII is providedin Section 4.

A wide variety of component types are referenced in the database coding system. Data isavailable on most component types. Coding for component types without data is maintained, forreference purposes, to allow for future additions to the database. In general, the data emphasizesmajor component types and failure rates which are dominated by top-event failure frequencies fromPSA studies. Most of these components are of the active type (i.e. they rotate or move), althoughpassive components (i.e. such as the reactor vessel and transformers) are also included.

The systems represented by the majority of the components are listed for each facility inTable IV. In general these are the most important safety systems, safety-related systems and keyprocess systems that are most commonly analyzed in PS As. The typical function and descriptions ofthese systems are provided in Ref. [8].

3. INSIGHTS FROM THE DATA COLLECTION PROCESS

The collection of component reliability data is invariably a tedious task unless a system is inplace to perform this on a continuous long-term basis. This was rarely the case until relativelyrecently for research reactor facilities. By contrast, many power reactors have had formalizedcollection systems for component reliability data for many years. The lack of staff resources atresearch reactor facilities is one of the main reasons for the absence of a formal system. Anotherfrequent difficulty is the lack of a computerized system for documenting maintenance and operatingrecords. This means that the collection of field data from a variety of hard copy recording systemsis time consuming. The quality of failure information also varies; it is primarily determined by theskill of maintenance and operations staff and how useful this type of information is regarded byreactor staff.

The features noted above are also not uncommon for non-nuclear process plants. Many of thecontributing facilities utilized students for data collection and analysis.

After the data collection and analysis process, very useful feedback was received on operationsand performance of equipment maintenance which led to improvements on equipment test andmaintenance procedures and in the failure record keeping process. Identification of potential incipientfailures and the trend of decreasing component reliability were other benefits obtained from theprocess. Generally, only when maintenance and operations staff can see direct usefulness of areliability data system will improvements be made in the quality of inputting field data.

4. USE OF THE DATABASE

4.1. LOCATION OF COMPONENT RELIABILITY DATA

This section describes the process for use of the reliability database. To locate a specificcomponent in the database, Table I should first be consulted. This list provides an alphabetic orderingby description/name of the different component groups. These component groups are defined ascomponents of a given general component category (Table II column 1) e.g. sensors, which have

different functions (e.g. flow sensors, level sensors). Having identified the two letter componentgroup coding from Table I column 1, Table II is then consulted to locate the description of the closestmatch for a desired component. Table II, column 6 provides a component type listing which givesthe highest level of description for a component. For example, different types of pressure sensorsmay be identified. The component type coding is a three letter code, given in Table II, column 5.Table II provides a complete listing of the component category, group and type descriptions, andcodes in alphabetical order of the component type code. Table II is utilized by first locating thedesired two letter component group code, provided in alphabetic ordering in column 3, and thenreviewing the associated list of component types in column 6 until the closest match of a desireddescription is found.

Having identified the most relevant component type by its three letter identification code,Table V can then be used to provide an overview of the number of facilities which have recorded dataon that component type. Table V also provides the relevant component type populations for eachcontributing facility. Table VI summarizes information on component types including manufacturer'sinformation for each contributing facility. The table is presented per facility. A three-character codesimilar to that used in Table V is associated with each component type. To locate the specificreliability data available for the identified component type, Table VII is used.

Table VII, column 1 lists the three-letter component type codes alphabetically. Having locatedthe component type code, the available data on that component for each facility can then be found.The legend for Table VII provides the necessary explanations for each of the columns. The two basicparameters: failure rate and failure per demand, with associated 90% confidence bounds, areprovided. The raw data on component population, operating or calendar time, number of failures ordemands are provided for the user as a check on the extent of the raw data.

4.2. ACCURACY OF RELIABILITY DATA

In addition to statistical uncertainty, discussed in Section 4.4, there are a number of causeswhich contribute to the inaccuracy of reliability data. Those causes influence both generic andfacility-specific data. The following sections discuss the various causes.

The causes of differences in reliability data can be grouped in two areas, namely:

differences in data collection or data processing;the actual component reliability is different.

In each of these areas a number of individual factors influencing reliability parameters has beenidentified. A short discussion of the most important factors is given below. Also, a discussion on dataselection is included.

4.2.1. Data collection and processing

The inaccuracy in reliability data caused by data collection or data processing can be significant.Factors related to the following are discussed here:

data sources;the ways the data is collected;data processing;definitions.

Data sources

The raw data is collected from historical records — i.e. log books, maintenance work recordsand test records. While the log books are generally considered to be the most accurate, a number offailures, especially on non-safety equipment, may not have been recorded. However, collecting datafrom the log books is extremely time consuming. Maintenance work orders are considered to be the

10

most complete records, but the reliability of the information depends on the person completing thereport. In many cases these are maintenance staff themselves, therefore the accuracy of the records(usually not computerized in research reactor facilities) varies. The direct consequence of incompleterecords is usually an overestimation of component reliability. Therefore the reliability data may bebiased.

Events without work request

Sometimes, relatively minor failures (such as mis-positioned valves) are reported during a testwithout a work request having been prepared. One example is a valve that opens only on second trialduring a test (or after a small, local repair). Only a comment on a test sheet is written. There is noformal work order or any other documented evidence. Since some of the failures are not accountedfor, reliability could be overestimated.

Failure of supporting equipment

Equipment failures may often be directly related to the failure of auxiliary equipment, supportor control systems. Such failures, although effectively disabling the component, are not failures ofthe component. Some databases do not separate such failures. Since supporting equipment failurescould actually dominate overall failure rate, this can cause substantial inaccuracy in the reportedfailure rate.

Coding errors

Coding errors are a classic problem encountered in every data collection exercise. Codingerrors are present in both computerized and manual data collection, and are generally related todiffering interpretations of criteria.

Failure rate denominators

The number of failures collected from the log books or maintenance/testing sheets are only oneinput used for the failure rate calculation. The number of demands, the failure exposure time or thecomponent's running time, are also essential. In the standard failure rate calculation, the denominatoris a quantitative measure of the stress that the component was subject to, related to a specific type offailure which may occur (failure mode).

The way the failure rate denominators are determined may produce a sizeable inaccuracy in acomponent's calculated failure rate. For equipment usually in standby mode, the data sourcesavailable today provide separate data on failures to start and failures to run (and sometimes on otherfailure modes such as leakage/rupture). The denominator for failures to run is a component's actualrunning time, which is usually estimated (e.g. 1 hour per test) and sometimes recorded.

4.2.2. Component reliability

Component reliability is a function of its design, use and maintenance. Components designedfor specific research reactor application (especially safety related) are usually highly reliable andshould be maintained as such during their lifetime. The reliability data, however, often showvariations which are related to operating conditions and practices, component application andmaintenance, and testing practices. A brief discussion of the influence of each of these is givenbelow.

Operating conditions and practices

A facility's operating conditions and practices may greatly influence component reliability.Some of the influence factors are:

11

operating mode;operating time and demands;operating environment.

The operating mode has been recognized as influencing equipment reliability, especially onactive components (such as pumps). Some data sources provide separate data for running, alternatingand standby categories. In the IAEA survey [9], variations of more than two orders of magnitudehave been documented for the failure to run of motor-operated pumps when comparing betweenalternating pumps, running pumps and pumps where no mode has been specified. This findingsupports the view that failure data for similar equipment having differing operating modes should bekept separate.

A component's failure to start may be caused by a demand related stress (e.g. vibration), orstress in standby (e.g. corrosion) or a combination of both. Most data sources disregard thesedifferences and provide data on failure to start either as demand related or time related. When timerelated data are provided, the failure rate denomination is usually calendar time, or sometimes plantoperating time. Since similar components at a different location may have a substantially differenttest interval, the actual number of demands in a period may vary, which in turn may greatly influencethe failure rate. Some data collection systems also systematically collect information on the numberof demands; in others the number of demands is estimated on the basis of testing demands owing tothe costs of collecting the information.

Operating conditions may also influence component reliability. Examples of this would beambient temperature, humidity, chemical control, radiation fields and vibration.

Design and application

Design and application of a component will have an important influence on reliability. Theapplication of the component will determine the operating mode and environment. Variations due tothese causes has been discussed in previous sections.

Maintenance and testing practices

Significant plant-to-plant variations for otherwise identical components can be identified. Thesevariations are most probably caused by facility-specific maintenance and testing differences. Theinfluence of the testing interval and practice has been extensively investigated. The testing intervalhas an influence on the failure rate, but it is strongly related to component type. The testing intervalhas greater influence on components where standby stresses dominate failure probability (usuallymotor operated valves) and lower on components with higher demand stresses (such as dieselgenerators and similar).

4.2.3. Data selection

As discussed, a number of factors may influence reliability data. Although it is difficult toquantify these, an order-of-magnitude estimate could be made.

The overall effect of the factors noted below can therefore substantially influence the results.

Since there is the possibility of a considerable variation in reliability data between differentfacilities, facility-specific data is the best possible source. However, when this data is sparse, otherdata sources must be used. In this case, their compatibility and applicability should be carefullyassessed.

ESTIMATE OF RELIABILITY DATA ACCURACY WITH VARIOUS CAUSES OF VARIABILITY

Collection related (comprehensiveness)Failure severity/failure modeDemand/operation attributesFailures in shut down taken into accountNon-representative samplesCollection of denominatorsSite effects (testing, maintenance)

2 to 5< 2< 222 to 102 to 52 to 10

When adopting reliability data from a data source, the definitions and their compatibility arefirst assessed. The background of a data source, including the ultimate data source,comprehensiveness of the data collection and data processing methods should be considered next.Finally, for reliability data originating at a research reactor, design (including age of design),operation, testing and maintenance practice should be examined for compatibility.

Although even the most careful data selection would not fully exclude the possibility of adoptingincompatible data, the fact that the factors contributing to data accuracy have been recognized shouldensure that the choice of data is reasonable.

4.3. RELIABILITY DATA ON COMMON CAUSE FAILURE

Quantification of common cause failure (CCF) data, in particular for system designs withredundant components, is an important aspect of PSA studies. CCF is also one of the most difficultareas in principle and in practice to obtain data. Collecting and reporting CCF data is a special aspectof reliability data collection. It is beyond the scope of this report to provide quantified data regardingcomponent CCFs, as defined in Ref. [7], Section 5.2.5. Therefore CCF specific data are not includedhere. To provide this type of data requires a detailed review of individual failure events. The failuredata provided by participants may include some common cause events. Experience with generic CCFdata has shown that it is very unlikely that the common cause contribution is a significant percentageof the recorded failure events. It can therefore reasonably be assumed that data uncertainties due tocommon cause failures are negligible compared with statistical uncertainties, Section 4.4, and theother contributing sources of inaccuracy, Section 4.2, in the data.

4.4. UNCERTAINTY BOUNDS

Following accepted practice in most databases, statistical uncertainty is calculated as discussedin Ref. [7], Appendix D. The 90% confidence range with 5% and 95% limits around the mean valueis defined. As noted in Ref. [7], failure rates and failures per demand utilize different expressionsfor the uncertainty calculations, although the differences between the calculations are not large. Thespreadsheet software EXCEL, version 4.0A, used for the production of the Table VII database,provided the necessary chi-square and F function variables needed for the uncertainty calculation.

The uncertainty bound values for the failure rates are provided in the last columns of Table VII.Note that the uncertainty bounds associated with a demand failure are in dimensionless units. Forcases with zero failure the numerator is set to 0.693 (taken from the 50% chi-squared value for onefailure) for the entry in the "failure rate" column of Table VII and a zero value is entered into the"5%" sub-column of the "90% confidence bounds" column. In all other cases the entry in "failurerate" column is the mean failure rate.
