COMMENTS ON PROPOSED VALVE FAILURE REPORTING CRITERIA - NPRDS USERS GROUP (NUG)MEETINGNO.12 ACTION 4.5 In our previous NUG meeting, you led a discussion and provided recommendations for improved guidance on identifying and reporting valve failures. All NUG members were asked to provide comments, from a user's point of view, on the proposed valve failure reporting criteria. Therefore, we have enclosed the attached markup which incorporates our comments. We have also enclosed an example of one plant's local leak rate acceptance criteria upon which operabi-l lity of a specific valve (e.g., MSIV) fio~s etermjA is d d.

As indicated in the ntgehsent.

5. The leakage contributed to a challenge to the Technical Specification limit such that a decision was made to repair the

}

valve prior to exceeding the limit. or

6. The repair was necessary to pass the LLRT (i.e..

either the site specific Technical Specification local leak rate acceptance criteria or the 10 CFR 50. Appendix J combined leak rate acceptance criteria could not be achieved without the repair). or 7.

The leakage was judged to be a significant fraction of the ILRT limit.

Attn. Freedom of Information Act Request Mr. Grimsley Pursuant to the Freedom of Information Act, as amended, 5 U.S.C. S 552, Public Citizen's Critical Hass Energy Project hereby requests copies of the following records:

1.

A complete listing of all conditions, situations, mishaps, accidents, or any kind of event included in the Nuclear Plant IXsliability Data System (NPRDS), including, but not limited to individual component failures and records of all other events it collects.

In addition, records explicitly defining what kind or type of events are reported to the NPRDS would also be appreciated.

2.

Any and ali analyses of nuclear power plant operating experience which use the NPRDS or any of the information contained therein.

Such analyses may include, but are not limited to, analyses of aging of plant systems or components: recurring problems or deficiencies in plant systems or components; assessments of particular systems or compenents; precursors to major events; or any other type of analysis that may have been performed using the NPRDS.

3.

Any and all assessments or evaluations of the performance of the NPRDS system done since the system's inception including, but not limited to, the criteria against which the performance of the system is measured and the methodology used for assesoment and evaluation, the assessments or evaluations themselves, and correspondence related to or j

concerning the performance of the system.

This request pertains to all records in the posession of the Nuclear Regulatory Commission (NRC), its licensees, or in the possession of contractors or subcontractors of the NRC or its licensees.

In this request, " record" includes, but is not limited to, any memoranda, formal or informal correspondence, reports, studies, reviews, letters, computer memories and printouts, information transfer systems, audio and video tapes, movies and any other form of communication, in the possession of any individual or office in the NRC, whether generated by the NRC, its contractors, the nuclear industry or any other source.
