March 16, 1984 Dr. A. C. Thadani, Chief Reliability and Risk Assessment Branch Division of Safety Technology Office of Nuclear Reactor Regulation Mail Stop P-216 U. S. Nuclear Regulatory Commission Washington, D. C. 2.0555

Dear Dr. Thadani:

Enclosed is the February monthly report for the activities sponsored by your Branch. Also included are the computerized budget summaries and the fee recovery cost status for each program requiring it. I would suggest that you and your staff review the reports to determine whether there are any dis-crepancies. If there are, please notify the principal investigator.

Note that the funds allocated for FIN A-3366 are nearly spent and that the NRC program office was informed of this March 15, 1984 as required by revised Manual Chapter 1102, dated September 24, 1982. Please send the balance of expected funds so that the level of effort may continue without interruption.

i We hope this meets with your approval. If there are any questions re-garding format, distribution, or budget reporting, please contact Mr. A. J.

I Weiss, Administrative Technical Assistant, FTS 666-4473.

Sincerely yours, 1

'i Branch NRC Technical Monitor: Ed Chow, Reliability and Risk Assessment Branch

1. Scope / Purpose The purpose of this project is to review those aspects of the Shoreham PRA leading to the estimates of the frequencies of the accident sequences re-i sulting in a " core vulnerable" state and to determine the accuracy of these estimates.

2. Schedule / Milestones A letter of the findings will be submitted to NRC at the completion of each task according to the following schedule.

Task 1: Draft Report 4/15/84

,.i Task 2: Questions to the Applicant 11/31/83

.; Task 3: Final Report Two months after receiving final

]'

comments by NRC and licensee.

, . 3. Progress to Date U The review and modification of support system event trees continued. The system fault trees received from LILC0 (on magnetic tape) have been loaded

' to the BNL computer system. The review of the internal flood event trees i

was initiated. A list of alarm-response procedures required for the review of the internal flood event has been requested from LILC0 by phone. A

-] meeting with LILCO personnel on the internal flood event trees has been scheduled for March 8,1984.

1 4. Problems and Delays 1

None.

5._ Next Reporting Period

-The development of core damage fault trees will be contir.ued. Quantitative evaluation usir.g the core damage trees will be initiated. Review of the

, internal flood will be completed.
