x s uc January 5, 1981 Director of Nuclear Reactor Regulation Attention:

Mr. Robert W. Reid, Chief Operating Reactors Branch No. 4 Division of Licensing United States Nuclear Regulatory Commission Washington, D.C.

20555

Dear Mr. Reid:

Under separate cover we are transmitting three (3) originaland forty (40) conformed copies of this letter and Attachment A for application of an Amendment to Facility Operating License No.

NPF-3 for the Davis-Messe Nuclear Power Station, Unit No. 1 (DB-1).

This amendment application proposes changes to the current DB-1 technical specifications.

This would allow the de-automation of Level 5 of the Safety Features Actuation System (SFAS). As a result, the.ong term post-loss of coolant accident (LOCA) shifting from the injection mode to the recirculation mode of core cooling will be manually accomplished from the control room.

This specific request stems from several discussions surrounding the Decenber 5, 1980, SFAS actuation with your staff.

Its intent is to provide resolution of concerns raised by your staff related to potential damage due to inadvertant or premature alignment of emergency core cooling systems (ECCS) to recirculation modes of operation, as well as those we reflected in a July 13, 1979, request for a license amendment.

Attachment A identifies the specific proposed changes to the technical specifications, the safety evaluation and the schedule to implement the proposed amendment. Also attached are marked up elementary wiring drawings of the BWST Outlet Valve (Drawing No. E-52B SH - 19A) and the Containment Emergency Sump Valve (Drawing No. E-52B SH - 19B) indicating the proposed modification to de-automate this function.

Attachment B provides the draft proposed modifications to the emergency operating procedures and the system operating procedures that are to be made reflecting the actions required to manually initiate long term post - LOCA recirculation core cooling. All control room personnel will be trained in these procedural modifications prior to their standing watches after system modification. Additionally, the prime responsibility for ensuring the manual shifting will be assigned to a licensed operator stationed in addition to those currently required by the DB-1 technical specifications THE TOLEDO EDISON COMPANY EDISON PLAZA 300 MACISON AVENUE TOLEDO. OHIO 43652 8101cf006

Docket No.

50-346 License No.

NPF-3 Serial No.

675 January 5, 1981 (this is planned to be the same additional operator currently stationed for reactor coolant pump termination upon injection mode initiation).

Although this effort addresses the imnediate concerns, Toledo Edisor. will further pursue the questions raised by your staff concerning the DB-1 SFAS compliance with IEEE 279-1971. A joint meeting between your staff.

Toledo Edison, Bechtel Associates and Consolidated Controls Corporation is recommended during the week of January 26, 1981. At that time standard compliance and any longer term actions can be discussed.

Attachment A is determined to be a Class III amendment request. A $4,000.00 check i= enclosed as per 10CFR170. Action taken on this request will preclude the need for approval of our July 13, 1979, submittal.(Serial No.

527).

Therefore, we request suspending its review until notified otherwise by Toledo Edison.

Ve.ry,truly,yours, ff ;
