Mr. John E. Dolan Vice Chairman Engineering and Construction 1 Riverside Plaza Columbus, OH 43216 Gentlemen:

The NRC's Office for Analysis and Evaluation of Operational Data (AE00) has completed an assessment of D. C. Cook Nuclear Plant, Unit Nos. I and 2, Licensee Event Reports (LERs) (Unit 1 - 24 LERs; Unit 2 - 18 LERs) as part of the NRC's Systematic Assessment of Licensee Performance (SALP) Report. The report was mailed to you on January 13, 1986.

Enclosed (Attachment C) is the assessment of the LERs from D. C. Cook Units 1 and 2.

In general, AEOD found these LERs to be of marganally acceptable quality based on the requirements contained in 10 CFR 50.73. The enclosed report provides the basis for this finding.

In addition, AEOD completed a study (AEOD/P504) of unplanned reactor trips that occurred in 1984. A summary table of reactor trip frequencies from the study is provided in Attachment A.

Finally, AE00 also completed a study (AE0D/P503) of ESF actuations that occurred during the first half of 1984. Several summary tables from that study are provided in Attachment B.

As part of the study of ESF actuations, AE00 noted the following specific problems associated with D. C. Cook.

1.

Nine units, including D. C. Cook 2, were of potential concern because they appear to have been experiencing repeated unresolved actuations which could ultimately challenge continued equipment operability and proper personnel response.

2.

Six units, including D. C. Cook 2, had a relatively high number of false actuations of radiation monitors.

The actuations were primarily associated with radiation monitor software problems which led to isolation of containment purge. This software problem did not appear to be generic to the other units studied.

APR - 3 1986 Corporation We are providing a copy of the AEOD assessment so that you might be aware of the findings and take action to improve the overall quality of future LERs.

We request that you provide Region III with the actions you intend to take to improve the overall quality of future LERs.

We appreciate your cooperation with us in this matter.

If you have any questions, please contact W. G. Guldemond (312/790-5574).

Definitions 1.

Valid (design basis) actuation:

the measured parameter actually reached the intended actuation setpoint and the condition that the ESF was intended to mitigate actually existed.

2.

Valid (non-design basis) actuation:

the measured parameter actually reached the intended actuation setpoint but the condition that the ESF was intended to mitigate did not exist. These ESF actuations resulted primarily because the actuation setpoints, as governed by the technical specification, were set very close to the parameter background levels experienced during various unit operational modes. These ESF actuations were considered to be valid but did not represent a required response to a design basis event. Rather, they were actuations resulting from non-design basis conditions, such as a accumulation of radioactive trash in front of a radiation monitor during refueling operations. These valid but non-design basis actuations were primarily associated with either toxic gas monitors or radiation-related monitors. The ESF actuations which resulted from these setpoints being reached were principally associated with isolation of the containment or auxiliary building, or with isolation of the control room emergency ventilation.

3.

False actuation:

the measured parameter did not reach the intended actuation setpoint. These actuations were a result of something other than the measured parameter reaching its intended setpoints. They were caused fairly equally by spurious signals, equipment failures, or problems related to personnel. These false ESF actuations principally affected systems whose functions were associated with either isolation or ventila-tion. The main parameters involved with these false actuations were radia-tion and loss of power.

ENCLOSURE AE00 INPUT TO SALP REVIEW FOR D. C. COOK 1 AND 2 Introduction in order to evaluate the overall quality of the contents of the Licensee Event Reports (LERs) submitted by D. C. Cook I and D. C. Cook 2 during the April 1, 1984 to September 30, 1985 Systematic Assessment.of Licensee Performance (SALP) assessment period, a sample of each unit's LERs was evaluated using a refinement of the basic methodology presented in I

NUREG/CR-4178. The sample consisted of 24 LERs for D. C. Cook 1 and 18 LERs for D. C. Cook 2, which represents fif ty percent of the LERs that were available for each unit at the time the evaluation started. See Appendix A for a list of the LER numbers in the sample.

It was necessary to start the evaluation before the end of the SALP assessment period because the input was due such a short time af ter the end of the SALP period. Therefore, not all of the LERs prepared during the SALP assessment period were available for review.

Methodology The evaluation consists of a detailed review of each selected LER to determine how well the content of its text, abstract, and coded fields met 2

3 the requirements of 10 CFR 50.73(b), NUREG-1022, and Supplements 1 4

and 2 to NUREG-1022.

The evaluation process for each LER was divided inte two parts. The first part of the evaluation consists of documenting comments specific to the content and presentation of each LER. The second part consists of determining a score (0-10 points) for the text, abstract, and coded fields of each LER.

1

The LER specific comments serve two purposes; (1) they point out what the analysts considered to be the specific deficiencies or observations concerning the information pertaining to the event, and (2) they provide a basis for a count of general deficiencies for the overall sample of LERs that were reviewed. Likewise, the text, abstract, and coded fields scores serve two purposes:

(1) they serve to illustrate in numerical terms how the analysts perceived the content of the information that was presented, and (2) they provide a basis for the overall score determined for each LER. The overall score for each LER is the result of combining the scores for the text, 6bstract. and coded fields (i.e. 0.6 x text score + 0.3 x abstract score + 0.1 x coded fields score = overall LER score).

Evaluation Results No attempt is made at this time to explain differences between results for multiple Units beyond providing genef al conments, when applicable, in the Discussion of R6sul~s. 'However, as data is collected, scores for the t

units that have been eva'luated will.be presented for comparison purposes.

The results Of the evaluation are presented by unit and are divided into two categories:

(1) detailed inforniation and (2) summary information. The detailed infermation, presented in Appendices A through D, consists of LfR sample information (Appendix A), a table of the specific sceres for each saniple LiR (Appendit B), tables of the number of deficiencies and observation for the text, abstract and coded fields (Appendix C), and conc.ent sheets for each LER (Appendiz D).

When referring to these appendices, tne reader is cautioned not to try to directly l

correlate the number of comments on an individual c6mment sheel with the assigned scores, as the analyst has flexibility to consider the magnitude of a defittency when assigning scores.

I In ths case where multiple units are evaluated, the results dre submitted in one enclosure and the suramary tables are assigned an i

alphabetic character so that the dif ferent unitt can referente the same l

l 2

.e

~ -

- p v

y 3

g g

table numbers.

For example in this enclosure, the letters A and 3 assigned to a table number correspond to D. C. Cook 1 and 2, respectively.

Discussion of Results A discussion of the analysts' conclusions are presented below.

These conclusions are based solely on the results of the evaluation of the LERs selected for review and as such represent the analysts' opinion of each unit's performance (on a scale of 0 to 10) in preparing LERs that meet the necessary requirements concerning contents.

The analysts made no attempt to assess differences in scores or the number of deficiencies between D. C. Cook 1 and D. C. Cook 2 because sufficient information is not available concerning how LERs are prepared or reviewed at each unit.

Evaluation Results for D. C. Cook 1 Table 1A presents the average scores for the sample of LERs evaluated for D. C. Cook 1.

The reader is cautioned that the scores resulting from the methodology used for this evaluation are not directly comparable to the scores contained in NUREG/CR-4178 due to refinements in the methodology.

In order to place the scores provided in Table 1A in perspective, the scores from other units that have been evaluated using this methodology are provided in Table 2.

Additional units will be added to Table 2 as they are evaluated. Table 3A and Appendix Table B-1 provide a summary of the information that is the basis for the average scores in Table 1A.

For example, D. C. Cook l's average score for the text of the LERs that were evaluated is 6.4 out of a possible 10 points.

From Table 3A it can be seen

~

that the text score actually resulted from the review and evaluation of 17 different requirements ranging from the discussion of plant operating conditions before the event [10 CFR 50.73(b)(2)(11)(A)] to text 3

Percentage scores are the result of dividing the total points for a a.

requirement by the number of poin'ts possible for that requirement.

(Note: Some requirements are not applicable to all LERs, therefore, tne number of points possible was adjusted accordingly.) The humber in parenthesis is the number of LERs for which the requirement was cor.sidered applicable, b.

A percentage score for this requirement is meaningless as it is not possible to determine f rom the information available to the analyst whether this requirement is applicable to a specific LER.

P 1

T

pr esentat ion. The percent scores in the text summary section of Table 3A

. provide an indication of how well each text requirement was addressed by the licensee for the 24 LERs that were evaluated.

Discussion of Specific Deficiencies A review of the percentage scores presented in Table 3A will quickly point out those areas where the licensee is experiencing the most difficulty in preparing LERs. For example, the licensee's percentage score for recairement 50.73(b)(2)(ii)(D), (i e., cause information for occurrences) is only 69%. Thirteen of the 24 LERs failed to provide adequate root cause information. Root cause information it very useful to the analyst who uses LER data for the purpose of looking for generic problems but rect cause information is even more important to the licensee that has experienced the event.

It is only through adequate determination cf root causes that implementation of the necessary corrective actions can be sccomplished, thereby preventing recurrence of the Event or similar cvents. The remsining deficiencies will be discussed in their relative order of importance.

The D. C. Cook 1 LERs were generally deficient in the area of assessing the safety consequences of the event. Eighteen of the 24 LERs did not contain or did not adequately discuss safety consequences ano implications. Sofety consequences were addressed in mott of the LERs but not in sufficient detail. Stating that "the consequences were minimal because f.he problem was quickly identified and corrected" is not adequate.

The discussion shnuld indicate what could have happened had the problen not been identif!ed and corrected quickly or indicate what other systems, components, and/or procedures were availaole to mitigate the consequences.

Likewise, it is inadequate to state that "there were no safety cnnsequences because tne teactor wus shutdown" if it is possible to have the same scenario happen during power operatinn.

4

%A g -

4 For certain events, such as the unscheduled actuation of the Reactor Protection System (RPS) or an Engineered safety Feature (ESF) System, it may be enough to state that "the actuation placed the plant in a more conservative condition relative to plant safety", provided, of course, that there were no increased safety consequences as a result of the actuation.

Fourteen of the 18 LERs involving personnel error were deficient.

In half of these, personnel error was not explicitly given as a cause but had to be inferred from other discussions (e.g., corrective actions). Another common aeficiency in this area was failure to state whether the personnel error was cognitive or involved a procedural error. Often the type (i.e.,

licensed operater, maintenance supervisor, etc.) of personnel involved was not stated.

Five of the 10 LERs involving a component f ailure were deficient in that they did not provide failure mode, failure mechanism (immediate cause), and/or f ailure effect information. Such information can of ten be inferred from other areas of the LER but this requires certain assumptions on the part of the reader. Failure mode, mechanism, and effect information should be provided for each component failure and, in some cases, fault.

For example, if an operator inadvertently shuts a safety related valve, the reader would like to know precisely how this occurrence affected the plant (e.g., "no boron injection was possible from train A as a result of the valve being closed").

Another deficiency related to components involved requirement 50.73(b)(2)(ii)(L). Four of the LERs involving component failure dio not provide manufacturer and model number information in the text. This, or other identification information, should be provided whenever a component f ailure or a component design problem contributes to an event.

Although the corrective actions requirement percentage score is not below average, a large number (11 of 24) of LERs failed to provide all the necessary information concerning corrective actions.

It is not enough to i

f 5

discuss only the immediate corrective actions.

Those actions necessary to prevent recurrence of the event or similar events must also be discussed.

The success of these long-term corrective actions is obviously a function of how well the cause of each occurrence is determined. Without determining the root cause of each occurrence, adequate long-term corrective actions can not be planned.

Six of'the 12 LERs involving safety system trains did not provide adequate dates or times so that the unavailability time of the train could be determined. This kind of information is required as it becomes part of the generic data necessary to perform probabilistic risk assessments (PRAs).

Nine of the 24 LERs failed to provide the method of discovery for each Such component or system failure and/or procedural or personnel error.

information is required as it provides the reader with the details as to This what particular activity was in progress that led to a discovery.

kind of information may prompt others to implenent some of these same activities (e.g., semi-annual reviews, post-test walkdowns, etc.) at their facility.

Previous similar event information was not provided in 15 of the 24 LERs. The determination of whether or not any previous similar events have occurred at your unit (or units)'can aid in identifying recurring problems or trends.

If no previous similar events are found, the text should so state.

Energy Industry Identification System (Ells) component function identifier and/or system name codes were not provided in two-thirds of the LERs for D. C. Cook 1.

The text presentation was lower than average for three reasons:

1) information was not consistent as it was not presented in a structured fornet, 2) the text (and abstract) were presented in all capital letters which made it more difficglt to identify information that is normally capitalized (e.g., component designators, system names, modes, and 6

position titles), and 3) ma.ny of the " text presentations" consisted of only an abstract. Over half of the D. C. Cook's LERs (13 of 24) were abstracts with no text.

This is permissible, but when it is done, the abstract must contain all the information that is required to be in a text. This is often difficult to accomplish in the space available for an abstract and probably accounts for the lower than average overall text scores.

The abstracts were generally deficient in the areas of root cause, which is a reflection of the text deficiency in this same area.

In the coded field area, all the titles were deficient.

They all lacked infonnation concerning root cause and over half lacked a linking phrase. Most titles provided the result of the event, (i.e., why the event had to be reported). An adequate title should contain three elements:

root cause, result, and a phrase or words tht make it possible for the reader to understand how the two elements are linked. For example, a title such as " personnel error causes scram" contains root cause and result but does not tell the reader anythin about the intermediate details. This intermediate information (link) is useful for the reader who uses titles to select categories of LERs from a hardcopy file. The other items in the coded fields were generally good.

Evaluation Results for D. C. Cook 2 Tables 18 and 38 provide a summary of the D. C. Cook 2 evaluation.

See Table 2, in order to place the D. C. Cook 2 scores in perspective.

A review of Table 3B indicates that D. C. Cook 2 has essentially the same deficiencies as D. C. Cook l and therefore, a separate discussion of specific D. C. Cook 2 deficiencies is not required.

Table 4 provides a summary of the areas that require improvement for D. C. Cook LERs.

" minimal safety significance because all system functioned as designed".

More effort should be placed on providing a discussion of the safety implications or justification for the boiler plate statements.

Root cause information More details should be provided.

Root cause can sometimes only be inferred from the corrective actions.

Corrective action information Long-term corrective actions necessary to prevent recurrence and similar events should be discussed in each LER.

Failure mode, mechanism, Details concerning all three aspects and effect information of every component f ailure should be provided. While mode and mechanism are of ten provided, the reader is of ten unf amiliar with the precise effect that a specific component failure will have on a system and/or the plant.

Manuf acturer and model number Component identification information information should be included in the text whenever a component f ails or is suspected to have contributed to the event because of its design.

TABLE 4.

Areas Comments Safety train unavailability Sufficient dates and times should be included in the text to enable the reader to determination of the length of time that safety system trains or components were out of service.

Previous similar Previous similar events should be events reference (LER Number) or the text should state there are none.

Method of discovery Information concerning what activity led to the discovery of each occurrence discussed in the text should be provided.

Ells codes Codes for each component and system involved in the event should be provided.

Text presentation and The practice of providing an abstract readability with no text should be avoided except for very minor and easily explained events. An outline format is recommended; the use of all capital letters is not.

Abstract Root cause information was of ten inadequate.
