Purpose:

The scope _ of this work will be limited to addressing immediate NRC/NHR licensing concerns using the state-of-the-art codes and the analyses and experimental data developed from NRC/RES and other R&D programs. The analyses provided under this contract will form the basis for the licen-sing decisions required on the Westinghouse Standard Plant, FDA-(PRA por-tion) and the CESSAR-System 80 FDA review (PRA portion) with -respect to l severe accident considerations.

2. Work Performed During Period:

Work on this contract continues at a relatively low level of effort in Subtasks I.A, I.B. I.C, II. A, II.8, and III.A, which are related to the acquisition, maintenance and development of pertinent computer codes and to providing cognizance of the IDCOR program.

l 3. Problems / Delays:

11. Scope / Purpose :

- The scope of this work will be limited to addressing immediate-NRC/NRR -- -

licensing concerns using the state-of-the-art codes and the analyses and experimenta'l data developed' from NRC/RES and other R&D programs. Tne analyses provided under this contract helped form the basis for positions taken by the NRC staff as related to questions raised by the Commission, hearing board and intervenors as part of the Indian Point Hearing. Al so ,

the analyses will provide input- to the NRC staff's review of the Indian

' Point Probabilistic Safety Study (IPPSS) and the Zion Probabilistic Safety Study (ZPSS): '

2. Work Performed During Period:

The final draft of the summary report on the ZPSS review has been can-plated and sent to NRC.

Several IDCOR documents were reviewed in preparation for the first NRC/IDCOR Technical Exchange meeting.

3. Problems / Delays :

None.

t l 4. Summary of Progress to Date/ Milestones:

The milestone for completing the final version of NUREG/CR-3300 has been 4

amended to allow for the additional assistance discussed above in Item 2.

5. Next Reporting Period: .
