Docket No. 50-316 June 12, 1985 Mr. John Dolan, Vice President Indiana and Michigan Electric Company c/o American Electric Power Service Corporation 1 Riverside Plaza
- Columbus, Ohio 43216
Dear Mr. Dolan:
DIST oc e Gray File OELD BGrimes DWigginton ACRS 10 NRC PDR ORB¹1 Rdg HThompson EJordan JPartlow CParrish By [[letter::05000316/LER-1985-007, :on 841228,NDE Revealed Cracks in Seven 2-inch Rockwell-Edward Globe Valves,Similar to IE Info Notice 84-48 & Suppl 1 Description.Valves Isolate Reactor Coolant Loop Resistance Temp Detector Manifolds|letter dated March 20, 1985]], the Indiana and Michigan Electric Company provided an evaluation of the Exxon LOCA issue for the Donald CD Cook Nuclear Plant Unit No. 2.
This issue included evaluation of errors and reanalysis for the K(z) curve.
Supplemental information was received by letters dated April 3 and 26, 1985.
We have completed our review as documented in the attached Safety Evaluation and have concluded that the Cycle 5
LOCA analysis did not contain the errors of concern, the revised analysis utilized an evaluation model in conformance with Appendix K and the revised analysis verifies that the Cycle 5 K(z) curve ensures compliance with 10 CFR 50.46.
We note however, that a new analysis will be required for Cycle 6
This completes this issue for Cycle 5
Sincerely
/s/SVarga
