November 1, 1974 Re Indian Point Unit No. 2 AEC Docket No. 50-247 Mr. Edson G. Case, Acting Director Directorate of Licensing U. S. Atomic Energy Commission 7920 Norfolk Avenue Bethesda, Maryland 20014 Dear Mr. Case In response to your letter of Octbber 10, 1973 and as stated in our letter of September 18, 1974, an additional report has been prepared that specifically addresses the

" Anticipated Transient Without Trip" response for plants which contain Series 44 steam generators.

This report,

" Anticipated Transient Without Trip Analysis for Westing-house PWR's With Series 44 Steam Generators", (WCAP-8404) was submitted by the Westinghouse Electric Corporation on October 18, 1974 by letter from Dr. Romano Salvatori to Mr.

D.

B.

Vassallo.

The report completes the analysis performed for Indian Point Unit No. 2 in responding to the recommendations set forth in WASH-1270.

This same report (WCAP-8404) will augment the two previous Westinghouse Topical Reports WCAP-7486 and WCAP-8330.

The analysis discussed in these three reports demon-strates that no hardware modifications are required to mitigate the consequences of ATWT.

Very truly yours car:
