4 Irving Place. New Ycrk. N Y 100i03 Telephone (212) 460-3819 September 9, 1975 Re Indian Point Unit No. 2

'Docket No. 50-247 Mr. Karl R. Goller, Acting Director For Operating Reactors Division of Reactor.Licensing U.S.

Nuclear Regulatory Commission Washington,.D. C. 20555 Dear Mr. Goller In response to your letter of August 7, 1975, Con Edison has reviewed its program for testing containment leakage.

Based upon this review, no design modifications to the plant-are recuired to meet 10CF-R Part 50, A-Dpendix J requirements.

Because these regulatCions were published after Con.Edison's containmert leakage test program was developed, modifications to the Technical Specijfications are necessary, and are presently being7 drafted.

Completion of these modifications are expected by Niolember 14, 1975. At that time, the proposed changes to the Technical Specifications will be submitted to the Commission.

Con Edison is currently scheduled to meet with the Regulatory Staff this month to discuss a number of items of interpre tation for a similar program that has been develoDed for Indian Point Unit No. 3. If changes are required as a result of that meeting, Con Edison will implement them for the Indian Point Unit 114o.

2 containment leaklIage test program prior to performing the next integrated leak rate test.

Very truly yours C-4 znrb William J.
