1 and 2 Docket Nos. 50-315 and 50-316 License Nos.

DPR-58 and DPR-74 INSERVICE INSPECTION SCHEDULE Mr. Harold R. Denton, Director Offioe of Nuolear Reactor Regulation U.S. Nuclear ReguIatory Canmission Washington, D.C.

Reference:

Our Letter No. AEP:NRC:0730A dated Maroh 15, 1984

Dear Mr. Denton:

In the referenced letter, the American Electric Power Service Corporation and the Indiana K Michigan Eleotric Company requested that the Inservioe Inspection/Inservice Testing (ISI/IST) second ten-year interval for both Cook Nuolear Plant units oommenoe on a comaon date, July 1, 1987.

At the present time, the second inspeotion interval is scheduled to begin August 23, 1985 for Unit 1 and July 1, 1988 for Unit 2..

Based upon discussions with your staff during a 'meeting on March 27-28, 1984 and subsequent telephone conversations, we now request that the seoond ten-year interval for both units begins on July 1,

1986, one year earlier than stated in our previous letter.

This request is oontingent upon aoceptance of the following'code relief requests:

The Unit 2 reactor vessel beltline examination for the first ten-year inspection interval will be conducted during the mid-1987 refueling outage as presently scheduled, maintaining the 1974 edition with addenda through summer 1975 of the ASME B&PV Code Section XI as the governing code.

2.

Beoause the Unit 2 first ten-year interval is bei.ng shortened by two years, the scheduled examination of sane Class 1 and 2

welds will not be oompleted by July 1, 1986 requiring code relief for the first interval.

These welds will be examined at or near the beginning of the second ten-year interval to the code edition in effeot at that time.

These examinations will be credited toward the second inspection interval.

Mr. Harold R.

D n

~02M AEP:NRC:0730D 3.

The system pressur e tests for Unit 2 for the first ten-year interval will be conducted during the mid-1987 refueling outage as presently scheduled, maintaining the 1974 edition with addenda through summer

'!975 of the ASME BhPV Code Section XI as the governing code.

The change in the second interval start date for Unit 1 should have no effect on ISI required by ASME Section XI because there is no refueling outage scheduled between August 1985 and July 1986.

The effect on the IST program is that Unit 1's pumps and valves would continue to be tested in accordance with the 1974 Code edition with addenda through summer 1975 during the extension from August 1985 to July 1986.

Upon receiving the requested relief, we plan to submit an ISI program covering both units.

The timely review and approval of these requests by the Staff will allow us to allooate our manpower resources in a more efficient manner.

We would appreciate the expeditious handling of this request.

This document has been prepared following Corporate procedures which incorporate a reasonable set of controls to insure its accuracy and completeness prior to signature by the undersigned.

Very truly yours, R. F. Heringg Vice President RFH/cm cc:
