| This letter is in response to Mr.A.Schwencer's letter of January 3, 1979, wherein we were requested to submit Technical Specifications to change the isolation time of certain containment isolation valves on Unit l.On February 3, 1978, we submitted a proposed Technical Specification for Unit 2 which would change the isolation time of the containment purge and exhaust valves to 5 seconds and better reflect our response to Question 022.4 contained in Appendix Q of our FSAR.Please be advised that in the response to the NRC letter of November 28, 1978, entitled,"Containment Purging During Normal Plant Operation", submitted on January 4, 1979 we incorporated into Unit l,by reference, our February 3, 1978 sub-mittal.Your staff's review of the fuel handling accident inside contain-ment can be completed based on our January 4, 1979 submittal for both Units 1 and 2.T he attachment to this letter contains a proposed Technical Specifi-cation change for Unit 1 in accordance with the evaluation of a postulated 1 fuel handling accident inside containment, as requested by Mr.Schwencer.

INDIANA II MICHIGAN POWER COMPANY P. O. BOX 18 BOWLING GREEN STATION NEW YORK, N. Y. 10004 March 7, 1979 AEP:NRC:00129 Donald C. Cook Nuclear Plant Unit No. 1 Docket No.:50-315 License No: DPR-58 REGULATORY DOCKET FILE COPY Mr. Harold R. Denton, Director Office of Nuclear Reactor Regulation U.S. Nuclear Regulatory Commission Washington, D.C. 20555
Dear Mr. Denton:
This letter is in response to Mr. A. Schwencer's letter of January 3, 1979, wherein we were requested to submit Technical Specifications to change the isolation time of certain containment isolation valves on Unit l.
On February 3, 1978, we submitted a proposed Technical Specification for Unit 2 which would change the isolation time of the containment purge and exhaust valves to 5 seconds and better reflect our response to Question 022.4 contained in Appendix Q of our FSAR. Please be advised that in the response to the NRC letter of November 28, 1978, entitled, "Containment Purging During Normal Plant Operation", submitted on January 4, 1979 we incorporated into Unit l,by reference, our February 3, 1978 sub-mittal. Your staff's review of the fuel handling accident inside contain-ment can be completed based on our January 4, 1979 submittal for both Units 1 and 2.
T he attachment to this letter contains a proposed Technical Specifi-cation change for Unit 1 in accordance with the evaluation of a postulated 1 fuel handling accident inside containment, as requested by Mr. Schwencer.
We are requesting that the isolation time'or the valves listed as "Contain'-
ment Purge and Exhaust Valves" under item C of table 3.6.1 of Specification 3/4.6.3.1 be changed from 10 seconds to 5 seconds. In addition, it has been noted with this revised Technical Specification that only one purge air inlet path (two valves in series) and one purge outlet path (two valves in series) are to be open at any given time while in Modes 1, 2, 3 and 4. The reason for this additional change is for consistency with information pre-sented in our response to Question 022.4 which was also made applicable (1 to Unit 1 by reference in our January 4, 1979 letter.

Mr. Harold RE Denton AEP:NRC:00129 This Technical Specification change request has been reviewed by both the PNSRC and the required membership of the AEPSC NSORC , in accordance with the appropriate provisions of our Technical Specifications.
The result of these reviews indicates that the subject Technical Speci-fication change will not adversely affect the health and safety of the public.
This Technical Specification change request has only minor signifi-cance and is being submitted at the request of the NRC to supplement pre-viously transmitted information. Pursuant to the provisions of 10 CFR Part 170, no fee accompanies this submittal.
