SUBJECT:

Monthly Management Letter #10 Month of February 1985 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 the 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 l

None.

4. List of Subcontractors and Consultants

a. Subcontractors (1) Applied Risk Technology Corporation (ARTECH); P. J. Amico (2) Jack R. Benjamin and Associates, Inc. (JBA); J. W. Reed, M. W.

McCann, Jr.

b. Consultants (1) P. R. Davis

5. Concerns None.

6. Other The total expenditures noted in Attachment A, including liens, are approximately S190.3K. This amount exceeds the $121.9K carryover from FY84 by

$68.4K, but this last number includes subcontractor liens (for work not yet executed or authorized) of about $29K, so that the correct total is approximately $161.3K, or about $40K more than the carryover from FY84. A request for immediate funding in the amount of $40K was made to the NRC in the Monthly Program Report for January 1985.
