Docket No. 5346 License No. NFP-3 Serial No. 1122 TOLEDO February 1, 1985 EDISDN RcHARo P. CnousE

?sY (4191259 *221 Mr. Darrell G. Eisenhut, Director Division of Licensing Office of Nuclear Reactor Regulation United States Nuclear Regulatory Commission Washington, D.C. 20555

Dear Mr. Eisenhut:

This is in response to your December 27, 1984 Generic Letter 84-24 (Log No. 1670) concerning certification of compliance to 10 CFR 50.49, Environ-mental Qualification of Electric Equipment Important to Safety for Nuclear Power Plants.

The Commission has directed the staff to collect information on the status of compliance with the rule, evaluate the information and make recommenda-tions on needed action. Accordingly, pursuant to 10 CFR 50.54(f), each licensee of an operating reactor is required to submit, under oath and affirmation, no later than 30 days from the date of this letter, a certi-fication that:

REQUEST (a) The utility has in place and is implementing a Environmental Qualifi-cation (EQ) Program that will satisfy the requirements of 10 CFR Section 50.49 within the currently approved schedule for the plant without further extension:

CERTIFICATION FOR DAVIS-BESSE UNIT NO. 1 (a) Toledo Edison's Davis-Besse Nuclear Power Station Unit No. I has in place and is implementing an Environmental Qualification (EQ) Program that is within the currently approved schedule and meets the require-ments of 10 CFR Section 50.49. Toledo Edison Company filed a request (Serial No. 1089) for an extension of the scheduler requirement of 10 CFR 50.49(g) until February 28, 1985, for two lube oil pump AC motors for the high pressure injection pumps. .The request for extension of the deadline was granted by NRC letter of November 23, 1984 (Log No. 1649). The two environmentally qualified motors were delivered and installed, and no further extension will be required.

REQUEST (b) The plant has at least one path to safe shutdown using fully qualified equipment, or has submitted a Justification for Continued Safe Operation (JCO) pending full qualification of any equipment not fully qualified:

THE TOLEDO EDISON COMPANY EDISON PLAZA 300 MADISON AVENUE TOLEDO, OHIO 43G52 7 85020603 2,,

I;" ^= =37 850201~~w c ttp,:

o [$O)'

. ,n k CERTIFICATION FOR DAVIS-BESSE UNIT NO. 1 (b) Toledo Edison reconfirms that Davis-Besse has at least one path to hot shutdown (safe shutdown) using fully qualified electrical equipment.

REQUEST (c) All other equipment within the scope of 50.49 is either fully qualified or a JC0 has been submitted pending full qualification.

CERTIFICATION FOR DAVIS-BESSE UNIT NO. 1 (c) The Justifications for Continued Operation (JCOs) which were submitted previously are no longer relied upon as the qualification has been established for electrical equipment within the scope of 10 CFR 50.49, or the equipment has been replaced with qualified equipment.

The certifications do not apply to Regulatory Guide 1.97 Equipment that was not listed in our May 20, 1983 submittal. The schedule for qualifi-cation of Regulatory Guide 1.97 Equipment is not governed by 10 CFR 50.49(g), but has been established in the Regulatory Guide 1.97 Resolution Process, except for Regulatory Guide 1.97 Equipment which was specifically identified in our May 20, 1983 submittal.

The qualification status of two Agastat relays was changed since the issuance of the Environmental Qualification (EQ) Manual Revision 2 (our May 20, 1983 submittal). The qualification was established during our latest refueling outage.

We have reviewed the responses and any corrective actions to the following information notices and bulletin: IE Bulletin 82-04, IE Information Notices 82-11, 82-52, 83-45, 83-72, 84-23, 84-44, 84-47, 84-57, 84-68, and 84-78. The responses have identified the applicability of the IE Bulletin and Information Notices to Davis-Besse Unit No. 1. If deemed necessary, appropriate actions have been taken to correct the potential deficiencies concerning the environmental qualification of safety related electrical equipment.

l l Very truly yours ,
