Dear Dr..Thadani:

[ Enclosed is the November monthly report for the activities sponsored by 7 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 spent and that the NRC program office was informed of this December 16, 1983 as required by revised d-Manual Chapter 1102, dated September 24, 1982. Funds for A-3366 transmitted j in work order #20-84-133 have not been accepted by BNL due to the level of j effort estimated to do the work; discussions are under way between the NRC d'15 Program Manager and the BNL Principal Investigator to resolve the issue.

-j The funds received for FIN A-3740 as shown on the financial status page,

}; - does not reflect the additional $120,000 received in December.

s The total amount of unbilled costs through November for FINS A-3366 and A-3740 are $7,024 and $9,069 respectively, which will be billed to NRC in December.

p- We hope this meets with your approval. If there are any questions re-

.L garding format, distribution, or budget reporting, please contact Mr. A. J.

c.j Weiss, Administrative Technical Assistant, FTS 666-4473.

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 fe-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 Task 2: Questions to the Applicant 11/31/83 Task 3: Final Report Two months after receiving final s comments by NRC and licensee.

3. Progress to Date Qualitative review of the event tree was initiated. Review of the initiator and system fault tree was completed. A number of the documents requested by BNL to facilitate the PRA review, such as, the FSAR and Tech.

Spec., were received. Questions to the applicants were generated.

4. Problems and Delays I

None.

5. Next Reporting Period The qualitative review of the event trees will continue. System success I criteria will be examined. The questions to the applicant will be sent to L the staff.
