SUMMARY
An evaluation of the content and quality of a representative sample of the Licensee Event Reports (LERs) submitted by Wolf Creek'during the period from February 1, 1986 to February 28, 1987 was performed using a refinement of the basic methodology presented in NUREG-1022, Supplement No. 2. The results of this evaluation indicate that Wolf Creek LERs have an overall average LER score of 9.1 out of a possible 10 points, compared to a current industry average score of 8.2 for those unit / stations that have been
, evaluated to date using this methodology.
The principle weakness identified in the Wolf Creek LERs involves the requirement to identify failed components in the text [ Requirement 50.73(b)(2)(11)(L)]. The failure to adequately identify each component that fails prompts concern that possible generic problems may not be ioentified in a timely manner by others in the industry.
Strong points for the Wolf Creek LERs are the discussions of the root cause [ Requirement 50.73(b)(2)(ii)(D)], the failure mode, mechanism, and effect of failed component (Requirement 50.73(b)(2)(ii)(E)], and personnel and/or procedural errors [ Requirement 50.73(b)(2)(ii)(J)(2)].

LER QUALITY EVALUATION FOR WOLF CREEK Introduction
.In order to evaluate the overall quality of the contents of the Licensee Event Reports (LERs) submitted by Wolf Creek during the period from February 1, 1986 to February 28, 1987, a representative sample of the unit's LERs was evaluated using a refinement of the basic methodology presented in NUREG-1022, Supplement No. 2.1 The sample consists of a total of 15 LERs, which is considered to be the maximum number of LERs necessary to have a representative sample. See Appendix A for a list of the LER nusr.bers in the sample.
It was necessary-to start the evaluation before the end of the assesstent period because the input was due such a short time af ter the end of the assessment period. Therefore, all of the LERs prepared by the unit during the assessment period were not 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 meet the criteria of 10 CFR 50.73(b). In addition, each selected LER is compared to the guidance for preparation of LERs presented in NUREG-1022 and Supplements No. 1 and 2 to NUREG-1022; based on this comparison, suggestions were developed for improving the quality of the reports. The purpose of this evaluation is to provide feedback to improve the quality of LERs. It is not intended to increase the requirements concerning the
" content" of reports beyc,nd the current requirements of 10 CFR 50.73(b).
Therefore, statements in this evaluation that suggest measures be taken are not intended to' increase requirements and should be viewed in that light.
However, the minimum requirements of the regulation must be met.
1
-The evaluation process for each LER is divided into 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.
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 was evaluated. Likewise, the 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 determining an overall score for each LER. The overall score for each LER is the result of combining the scores for the text, abstract, and coded fields (i.e., 0.6 x text score + 0.3 x abstract score + 0.1 x coded fields score - overall LER score).
The results of the LER quality evaluation are divided into two categories: (1) detailed information and (2) summary information. The detailed information, presented in Appendices A through D, consists of LER sample information (Appendix A), a table of the scores for each sample LER (Appendix B), tables of the number of deficiencies and observations for the text, abstract and coded fields (Appendix C), and comment sheets containing narrative statements concerning the contents of each LER (Appendix D).
When referring to Appendix 0, the reader is cautioned not to try to directly correlate the number of comments on a comment sheet with the LER scores, as the analysts has flexibility to consider the magnitude of a j deficiency when assigning scores (e.g., the analysts sometimes make comments relative to a requirement without deduction points for that requirement).
Discussion of Results 4
A discussion of the analysts' conclusions concerning LER quality is presented below. These conclusions are based solely on the results of the evaluation of the contents of the LERs selected for review and as such 2
i l
represent the analysts' assessment of the unit's performance (on a scale of '
0 to 10) in submitting LERs that meet the criteria of 10 CFR 50.73(b) and j
.the guidance present in NUREG-1022 and its supplements. 1 i
Table 1 presents the average scores for the sample of LERs evaluated for Wolf Creek. In order to place the scores provided in Table 1 in perspective, the distribution of the latest overall average score for all unit / stations that have been evaluated using the current methodology is provided on Figure 1. Figure 1 is updated each month to reflect any changes in this distribution resulting from the inclusion of data for those units / stations that have not been previously evaluated or those that have ,
been reevaluated. (Note: Previous scores for those units / stations that are reevaluated are replaced with the score from the latest evaluation).
Table 2 and Appendix Table B-1 provide a summary of the information that is the basis for the average scores in Table 1. For example, Wolf Creek's average score for the text of the LERs that were evaluated is 9.0 out of a possible 10 points. From Table 2 it can be seen that the text score actually results from the review and evaluation of 17 different requirements ranging from the discussion of plant operating cenditions before the event [10 CFR 50.73(b)(?)('.1)(A)] to text presentation. The percentage _ scores in-the text summary section of Table 2 provide an indication of how well each text requirement was addressed by the unit for the 15 LERs that were evaluated.
Discussion of Specific Deficiencies A review of the percentage scores presented in Table 2 will quickly point out where the unit is experiencing the most difficulty in preparing iIRs. For example, requirement percentage scores of less than 75 indicate that the unit probably needs additional guidance concerning these requirements. Scores of 75 or above, but less than 100, indicate that the unit probably understands the basic requirement but has either: (1) excluded certain less significant information from many of the discussions concerning that requirement or (2) totally failed to address the requirement in one or two of the selected LERs. The unit should review the LER specific comments presented in Appendix D in order to determine why 3

it received less than a perfect score for certain requirements. The text requirements with a score of less than 75 or-those with numerous deficiencies are discussed below in their order of importance. In addition, the primary deficiencies in the abstracts and coded fields are discussed.
The manufacturer and/or model number (or other unique identification) was not provided in the text of the two LERs that involved a component failure, Requirement 50.73(b)(2)(11)(L). Components that fail must be identified in the text so that others in the industry can be made aware of potential problems. An event at one station can often lead to the identification of a generic problem that can be corrected at other plants or stations before they experience a similar event. In addition, although not specifically required by the current regulation, it would be helpful to identify components whose design contributes to an event even though the component does not actually fail. Be sure to give enough information to uniquely identify the failed component (e.g. manufacturer and model number).
The text presentation, while acceptable, could be improved by presenting the information in an outline format as suggested in NUREG-1022, Supplement No. 2.
Wolf Creek provided very good abstracts, but the presentation score would have been better if six of the abstracts had not exceeded the 1400 space limit. Information concerning safety consequences and previous similar events can be deleted from the abstracts if space is a problem. In addition, new information (i.e., information which was not discussed in the text) should not be introduced in the abstracts. If such information is deemed necessary in the abstract, the text should be revised so as to include it.
The main deficiency in the area of coded fields involves the title, Item (4). Twelve of the titles failed to indicate the root cause, six failed to adequately indicate the result (i.e., why the event was required to be reported), and three failed to include the link between the cause and the result. While the result is considered the most important part of the 8
title, the lack of cause information (and link, if necessary) results in an incomplete title. An example of a title that only addresses the result might be " Reactor Scram". This is inadequate in that the cause and link are not provided. A more appropriate title might be " Inadvertent Relay Actuation During Surveillance Test LOP-1 Causes Reactor Scram". From this title, the reader knows the cause was either personnel or procedural and surveillance testing was the link between the cause and the result.
Example titles are provided in Appendix D (Coded fields Section), for some of the titles that are considered to be deficient.
Table 3 provides a summary of the areas that need improvement for the Wolf Creek LERs. For additional and more specific information concerning deficiencies, the reader should refer to the information presented in Appendices C and D. General guidance concerning these requirements can be
