7 m., J 0 G73 Docket Nos. 50-416/417 Roger S. Boyd, Assistant Director for Boiling Water Reactors, L REVIEW SCHEDULE FOR GRAND GULF, UNITS 1 AND 2 We have performed a b:ief review of the information that is to be provided in forthcoming Amendment 2 to the Grand Gulf PSAR. This information was informally provided to us by _ the Project Manager.

This Amendment was to provide the additienal information that we identified in our January 11, 1973, memorandum (Tedesco to Boyd).

Our review indicates that che application is still not complete enough to allow us to conduct a meaningful review. ,

Our review of the information indicates the following deficiencies: -

1. A number of drawings previously submitted in the PSAR requires

- revision, including Figures 6.2-9, 6.2-196, 6.2-20, 6.2-22, and 6.2-23, to conform to the applicant's latest vacuum breaker and recirculation system designs.

2. Sections of the previously submitted PSAR text require revision, including Section 6.2.5.2.1, to conform to the latest recirculation .

system design and the capability of the system to perform its vacuum relief function.

3. The bypass leakage analysis requires detailed information regarding -

assumptions and equations used in the analysis, and proposed means to minimize the potential for and mitigate the consequences of bypass leakage.

4. The sensitivity study of hydrogen generation as a function of core

temperature that we requested at the December 15, 1972, meeting with the applicant has not been provided.

5. The Project Manager informed us that the applicant is ernsidering a change to a dual containment. This decision should be made before we begin our review.

Based on the above, we feel that the design of the Grand Gulf containments is not sufficiently complete to allow us to begin a 8806160071 080606- ,
