SUBJECT:

Monthly Management Letter #7 Month of November 1984 NRC FIN-A0801 Review of the Seabrook Probabilistic Risk Assessment

Dear Ms. Davis:

1. Project Description and Objective The Office of Nuclear Reactor Regulation is conducting a probabilistic risk assessment (PRA) review program in which PRAs performed and submitted to th.a NRC by license applicants and licensees receive comprehensive review and evaluation. The program is the responsibility of the Reliability and Risk Assessment Branch (RRAB).

A PRA of the Seabrook Nuclear Power Plant (Seabrook PRA) has been submitted to the NRC by Public Service Company of New Hampshire, an operating license (OL) applicant. The review of this document, whose title is "Seabrook Station Probabilistic Safety Assessment," is being performed as one project in the larger NRC program.

The objective of this project is to perform an expeditious and cost effective review of those aspects of the Seabrook PRA leading to the estimates of the frequencies of each plant damage state and the associated uncertainty spread to determine the accuracy of these estimates. The review will cover method-ology, assumptions, data, information sources, models, plant understanding, completeness of the analysis and other areas where inconsistencies may arise which could affect the quantitative or qualitative results.

2. Progress for Period

a. Work continued at steady pace during the month,

b. A. Garcia and G. Cumings (LLNL), and P. Amico ( ART) attended a meeting with A. Thadant and S. Davis at the NRC offices in Bethesda on November 28, 1984.

3. Work to be Accomplished Next Month

a. Work on the review will continue at a much' higher rate in order to complete and deliver to NRC a draft report in the month of December.

5. Concerns The concerns noted in previous monthly program reports have not been, and are

< not now expected to be fully resolved. The direction to be taken in the

- process of completing the draft report will be to do what we can with the information available to us, and to identify areas where the absence of information may be important to the results.
