R. QUAY SUI 3 JECT: AP600 RESPONSE TO REQUESTS FOR ADDITIONAL INFORMATION AND SUPPLEMENTAL INFORMATION TO THE RAI RESPONSES

Dear Mr. Quay:

Enclosure I contains the Westinghouse response to NRC requests for additional information on AP600. Specifically, responses are provided for the following RAls:

RAI OITS #

Seismic margin analysis:

230.133 - 230.138 5286 - 5291 230.139 5525 720.392 5505 Long-term cooling:

720.386 5134 l Level 1 PRA: '

720.400 5497 Ex-vessel phenomena:

720.408 5521 720.410 5523 l

Ily respondmg to the above mentioned RAls related to the seismic margin analysis, Westinghouse believes DSER Open item 19.1.3.2-1 is closed. This is item #1425 in the OITS.

t Also note that submittal of the responses to NRC questions on the in-vessel steam explosion 14 -

I evaluation (via Westinghouse letter DCP/NRC0915, dated June 13,1997) closes, from the j Westinghouse perspective, DSER open item 19.2.3.3-5 (OITS #1464).

These responses close, from the Westinghouse perspective, the RAls and DSER open items. The Westinghouse status column in the OITS will be changed to " Action N," except for OITS #5291

- whose status will be changed to "Confinn-N." The NRC should review these responses and inform _

Westinghouse of the status to be designated in the "NRC Status" column of the OITS.
