.NRC FIN-A0801 Review of the Seabrook Probabilistic Risk Assessment
~
Dear Ms. Davis:
.1;
' Project Descrlpt' ion 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 licencees receive comprehensive review.and evaluation.
The. program is the responsibilit.y of the. Reliability and Risk AssessmentBranch-(RRAS).
A PRA of the' Sea' brook Nuclear Power Plant (Seabrook.PRA) has been submitted to the NRC by Public Service Company of New Hampshire, an operating license (Oi.)
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 expediti'Eus and cost effective review of those' aspects of the Seabrook PRA leading to the estimates of the frecuencie's of each plant damage state and thE associated uncertainty spread to determine the accuracy of these estimates.
The review will cover methodology, assumptions, data, information sour.ces, models, plant understanding, completeness of the analysis and other areas where inconsistencies 'may arise which could affect the quantitative or qualitative results.
2.-
Procress for Period 4.
The project began on May 15th, b.-
Very little review effort was expended during the remainder of the month since the only document available was one cooy of tne PRA.
