Docket Nos.

50-315 and 50-316 ocT ~" 19$

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:

DISTRIBUTION:

,Docket fil.e>>

NRC PDR Local PDR ORB81 reading DEisenhut OELD EJordan TBarnhart ACRS; 10 OPA, Cfliles JTaylor SECY This is in response to the Indiana and Michigan Electric Company's

( IMEC) letters dated May 20, 1983, August 10,

1983, and September 26, 1983 which requested an extension of the deadline for final environmental qualification of certain Donald C.

Cook Nuclear Plant electrical equipment.

In these IMEC

letters, the specific equipment has been identified, reasons for the delays discussed, and dates provided by which time the equipment is to be fully qualified.

In addition, our staffs met on September 13, 1983 and as a result of the meeting, IMEC will document the discussions and agreements of the meeting and this documentation will serve as a basis for our review of the remainder of your equipment qualification program.

Under the regulations in 10 CFR 50.49 which were published in the Federal Register on Januay 21, 1983 and made effective February 22, 1983, licensees of power reactors are required, among other things, to submit a schedule for either the qualification or r'eplacement of, to the provisions of 50.49, the remaining electrical equipment important to safety not already identified as qualified.

This schedule must establish a goal of final qualification of the electric equipment by the end of the second refueling outage after March 31, 1982 or by March 31, 1985 whichever is earlier.

The regulations allow for the granting of requests for extension of this deadline by the Director, Office of Nuclear Reactor Regulation, to a date no later than November 30, 1985 for specified pieces of equipment if these requests are filed on a

timely basis and demonstrate good cause for the extension, such as procure-ment lead time, test complications and installation problems.

According to your submittals, the second refueling outage.after March 31, 1982 for Donald C.

Cook Nuclear Plant Unit No.

1 will end in early October 1983 and for Unit 2 will end approximately March 1984.

In the letter dated September 26,

1983, IMEC is requesting an extension until March 31, 1985 for the Donald C.

Cook Nuclear Plant Unit Nos. I and 2 equip-ment identified in the enclosure.

IMEC has also requested Until June 3, 1984 to complete the documentation files to assure complete traceability on a few remaining items and until June 3, 1984 to obtain or review the actual test reports on various lubricants.

For all of the items in the attachment, the principal deficiency is aging and specifically, the development of surveillance, maintenance, and replacement procedures based on your near-complete aging analysis.

The acceptance of your request for, extension due to;aging is also supported by your commitment to establish an expedited program to replace non-qualified equipment or to provide alternate measures to ensure accomplish-ment of the safety function while the detailed procedures are being written.

The resistance temperature detectors, in addition to aging, are subject to confirmation that chemical spray conditions were included with the qualification tests.

Some Barton pressure transmitters identified in the enclosure remain to be fully qualified because of outstanding submergence questions and addi-tional tests or relocation may still be required.

Specific instrumentation and control cables were tested but because of the nature and duration 'of tests and as a result of reanalysis, some additional testing, replacement or reloca-tion may be required.

The extensions requested in the above referenced IMEC letters fall within the allowable extensions anticipated by the rule.

Since the installation and modification schedules for much of the electric equipment for which you request extensions was established well,.in advance of the publication of the final rule and the requested extensions for the remainder of the electric equipment are based upon unforeseen delays in obtaining qualification test data and identification of equipment requiring qualification, your requested extensions appear to demonstrate good cause.

In the September 26, 1983 letter, IMEC noted for much of the equipment that the results of tests and actual replacement or installation in Unit 2 may exceed the requested extension date of March 31, 1985 due to the refueling schedules.

Every attempt should be made by IMEC to complete the qualificaton program within the time period approved.

IMEC also addressed the possibility that the new resistance temperature detectors (RTD) to satisfy the fire protection, Appendix R, review may not be installed in Unit 2 before the March 31, 1985 extension date.

The existing RTDs.should be qualified and as new or replacement equipment is installed, it should be qualified or the licensee notify the NRC in accordance with paragraph (h) of 10 CFR 50.49.

In regards to equipment to satisfy Regulatory Guide 1.97 (Rev. 2), the IMEC position in the September 26, 1983 letter is correct for equipment not yet identified by IMEC to satisfy R.G.

1.97 (Rev.

2) criteria.

Existing equipment should be qualified to satisfy existing requirements and the licensee, as discussed, should follow the provisions of paragraph (h) of 10 CFR 50.49 as the results of R.G.

1.97 (Rev.

2) analysis dictate.

Based on the foregoing, I find that your request for extension was filed in a timely basis and demonstrates good cause for an extension of time to com-plete final environmental qualification of the specified equipment.

An extension is therefore granted for Donald C.

Cook Nuclear Plant Unit Nos.

1 and 2 until March 31, 1985 for the items in the enclosure and until June 3, 1984 to complete documentation of items and to obtain or review actual test reports on various lubricants.
