INDIANA 8 MICHIGAN ELECTRIC COMPANY P.O. BOX 16631 COLUMBUS, OHIO 43216 June 23, 1986 AEP:NRC:0692AR Donald C. Cook Nuclear Plant Unit Nos. 1 and 2 Docket Nos. 50-315 and 50-316 License Nos. DPR-58 and DPR-74 ADDENDUM TO TECHNICAL SPECIFICATIONS FOR APPENDIX R TO 10 CFR 50, ALTERNATE SAFE SHUTDOWN Mr. Harold R. Denton, Director Office of Nuclear Reactor Regulation U.S. Nuclear Regulatory Commission Washington, D.C. 20555

Dear Mr. Denton:

The purpose of this letter is to modify our letter AEP:NRC:0692AJ, dated May 30, 1986, which provided our proposed Technical Specifications (T/Ss) for alternate safe shutdown. In the process of implementing the administrative controls associated with these T/Ss, we discovered that Specification 3.0.4 applies to these T/Ss for opposite unit shutdown support if they are interpr'eted literally. Such an interpretation could cause us unnecessary operational difficulties. For example, one unit cannot enter Mode 4 (from Mode 5) if the opposite unit does not have a centrifugal charging pump and the associated unit cross-tie flow path available. It was not our intention that the provisions of Specification 3.0.4 apply to our alternate safe shutdown capability. We proposed the compensatory action of posting fire watches in the unit lacking opposite unit support in those fire areas required in order to preclude loss of safe shutdown systems. We feel that this is adequate to maintain our safe shutdown capability in a fire scenario. Therefore, we have modified certain T/S pages of Attachment 3 to our letter of May 30, 1986 to state that Specification 3.0.4 does not apply.

The attachment to this letter contains all proposed changes to the Donald C. Cook Nuclear Plant Technical Specifications for alternate safe shutdown. It is intended that this attachment supersede Attachment 3 to AEP:NRC:0692AJ. Attachments 1 and 2 to that letter are unchanged by this submittal. We have indicated the changes proposed in the attachment to this letter that are different from those in Attachment 3 to AEP:NRC:0692AJ by using double margin bars.
