ATTN: Mr. Murray Selman Vice President, Nuclear Power Indian Point Station Broadway and Bleakley Avenue Buchanan, New York 10511 Gentlemen:

Subject:

Assessment of the Quality of Licensee Event Reports (LERs) - Indian Point Station, Unit 2 As part of the SALP process, the NRC Office for Analysis and Evaluation of Operational Data (AE00) evaluated LERs submitted during the recent SALP assessment period for the Indian Point Nuclear Generating Station, Unit 2.

The assessments (portions enclosed) were performed using a methodology similar to that described in NUREG/CR-4178, "An Evaluation of Selected Licensee Event Reports Prepared Pursuant to 10 CFR 50.73."

The NRC considers it important to achieve uniform, high quality LERs from all operating power reactors to enable licensees and AE00 to effectively identify

" precursor events" and emerging trends or patterns of potential safety significance. Generic studies triggered by events reported at specific units can lead to improvements in the level of reactor safety only if the available data-base is uniform and of high quality.

Based on a limited sample, AE00 concludes that the Indian Point 2 LERs sampled were of better than average quality as compared to other licensees that have been evaluated using this methodology. I invite you to review the enclosed analyses and to discuss the evaluation and any planned improvements to your event reporting system at the forthcoming NRC SALP management meeting.

Sincerely, I

SUMMARY

An evaluation of the content and quality of a representative sample of the Licensee Event Reports (LERs) submitted by Indian Point 2 during the August 1, 1985 to July 31, 1986 Systematic Assessment of Licensee Performance (SALP) period was performed using a refinement of the basic nethodology presented in a report entitled "An Evaluation of Selected Licensee Event Reports Prepared Pursuant to 10 CFR 50.73 (DRAFT)",

NUREG/CR-4178, March 1985. The results of this evaluation indicate that Indian Point 2 has an overall average LER score of 8.3 out of a possible 10 points, compared to a current industry average score of 7.9 for those units / stations that have been evaluated to date using this methodology.

The principle weaknesses identified in the LERs, in terms of safety significance, involve the requirement to provide identification of failed components. The failure to adequately identify the manufacturer and model number of the components that fail prompts concern that others in the industry won't have insediate access to information involving possible generic problems.

Strong points for the Indian Point 2 LERs are the discussions of the mode, mechanism, and effect of failed components, the discussion of personnel errors, and the discussion of the safety consequences of the

, event.

4 AE0D INPUT TO SALP REVIEW FOR INDIAN POINT 2 Introduction In order to evaluate the overall quality of the contents of the Licensee Event Reports (LERs) submitted by Indian Point 2 during the August 1, 1985 to July 31, 1986 Systematic Assessment of Licensee Performance (SALP) assessment period, a representative sample of the licensee's LERs was evaluated using a refinement of the basic methodology presented in NUREG/CR-4178. The sample consists of 11 LERs, which is half of the LERs that were on file at the time the evaluation was 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 after 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 meet 3

the requirements of 10 CFR 50.73(b), NUREG-1022 , and Supplements 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.

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 the overall score determined for each LER. The overall score for e&ch 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 these appendices, the reader is cautioned not to try to directly correlate the number of comments on a comment sheet with the LER scores, as the analyst has flexibility to consider the magnitude of a deficiency when assigning scores.

Discussion of Results A discussion of the analysts' conclusions concerning LER quality is e 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 represent the analysts' assessment of each units performance (on a scale of j

0 to 10) in submitting LERs that meet the requirements of 10 CFR 50.73(b).

Table i presents the average scores for the sample of LERs evaluated

! for Indian Point 2. 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. -

. 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, Indian Point's average score for the text.of the LERs that were ovaluated was 8.3 out of a possible 10 points. From Table 2 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)(ii)(A)] to text presentation. The percentage scores in the text'sommary section of Table 2 provide an indication of how well each text requirement was addressed by the licensee for the 11 LERs that were evaluated.

Discussion of Specific Deficiencies A review of the percentage scores presented in Table 2 will quickly point out where the licensee is experiencing the most difficulty in preparing LERs. For example, requirement percentage scores of less than 75 indicate that the licensee probably needs additional guidance concerning these requirements. Scores of 75 or above, but less than 100, indicate that the licensee probably understands the basic requirement but has either: (1) excluded certain less significant information from a large number of the discussions concerning that requirement or (2) totally failed to address a requirement in one or two of the selected LERs. The licensee should review the LER specific comments presented in Appendix 0 in order to determine why he 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 abstract and coded fields are discussed.

Many of the more important requirements (i.e., root cause, personnel error, safety assessment, and corrective actions) were discussed very tell. A review of the comments in Appendix D will aid in identifying any .

minor problems found in these requirements.

a. Percentage scores are the result of dividing the total points for a requirement by the number of points possible for that requirement.

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

b. A percentage score for this requirement is meaningless as it is not possible to determine from the information available to the analyst whether this requirement is applicable to a specific LER. It is always given 100%

if it is provided and is always considered "not applicable" when it is not.

The manufacturar and/or model numbtr (or other uniqua identification) t;as not provided in the text of four of the eight LERs that involved a component failure, Requirement 50.73(b)(2)(ii)(L). Components that f ail should be identified in the text so that others in the industry can be made aware of potential problems. In addition, although not specifically_

required by the current regulation, it would be helpful to identify components whose design contributed to an event. 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 problem.

An estimate of the elapsed time of the unavailability of a failed safety system was not provideo in six of seven LERs in which this requirementwasapplicable[50.73(b)(2)(ii)(H)]. Generally, if sufficient date and time information is provided for all major occurrences of the event, Requirement 50.73(b)(2)(ii)(C), it is sufficient to satisfy this requirement as the duration of the train failure can then be calculated.

Four of the eleven LERs reviewed f ailed to mention previous similar events or state that there were none, Requirement 50.73(b)(5). Previous similar events should be referenced appropriately (LER number if possible),

and if there are none, the text should so state.

Ten of the eleven LERs reviewed failed to include the Energy Industry IdentificationSystem(EIIS) codes. Requirement 50.73(b)(2)(ii)(F) requires inclusion of the appropriate EIIS code for each system ano component referred to in the text.

While.there are no specific requirements for an abstract, other than those given in 10 CFR 50.73(b)(1), an abstract should, as a minimum, summarize the following information from the text:

1. Cause/Effect What happened that made the event reportable.
2. Responses Major plant, system, and personnel responses as a result of the event.
3. Root / Intermediate The underlying cause of the

. Causes event. What caused the component and/or system failure or the personnel error.

4. Corrective Actions What was done immediately to restore the plant to a safe and stable condition and what was done or planned to prevent recurrence.

Indian Point 2 had good discussions of item numbers 1 and 3 above.

Item numbers 2 and 4 could use some improvement however . Scores for these items should improve if the responses and corrective actions information contained in the text is summarized in the abstract.

The main deficiency in the area of coded fields involves the title, Item (4). Five of the titles f ailed to indicate the root cause and three failed to include the result (i.e., why the event was required to be reported). While result is considered the most important part of the title, cause information (and link, if necessary) must be included to make a title complete. An example of a title that only addresses the result cight 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.

?

The operating mode (Item 9) was not provided in any of the 11 LERs, and two LERs f ailed to provide the power level. These items should be filled in on all LERs. For units with non-standard Technical Specifications (i.e., where the Technical Specifications do not define mode numbers for the various operating conditions) an "N" should be placed in Item 9.

The position title of the licensee contacts named in Item 12 was not provided in any of the sample LERs.

. Table 3 provides a sumary of the areas that need improvement for the Indian Point 2 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 found in NUREG-1022, Supplement No. I and 2.

During the initial manual load decrease, why was the

" magnitude" of the load decrease sufficient to cause

a dropped rod runback? Does the procedure allow the
override of a NIS runback?
4. 50.73(b)(2)(ii)(L)--Identification (e.g. manufacturer and model no.) of the failed component (s) discussed in the text-is inadequate. The broken hose is identified very well, but because the speed control system of No. 22 MBFP did not respond and will be replaced, it should also be identified in the text.
5. 50.73(b)(41--Discussion of corrective actions taken or planned is inadequate. Since the cause of the clogged orifices in No. 22 M8FP is not given, a question remains concerning whether or not the new i Lovejoy speed control system will also be susceptible to clogging?

Abstract 1. 50.73(b)(11--Summary of plant responses is
