O 80 06 ovo o n UNITED STATES OF AMERICA NUCLEAR REGULATORY COMMISSION In the Matter of The Toledo Edison Cogany and
)
Docket No. 50-346 The Cleveland Electric
)
Illuminating Cowany
)
(Davis-Besse Power Station, Unit No. 1)
)
CONFIRMATORY ORDER I
The Toledo Edison Conpany (TECo) and The Cleveland Electric Illuminating Comany (the Licensees) are the holders of Facility Operating License No. NPF-3 which authorizes the operation the Davis-Besse Nuclear Power Station, Unit No.1 (the facility) at power levels not in excess of 2,772 megawatts thermal.
The facility is a pressurized water reactor located at the Licensees' site in Ottawa County, Ohio.
II Following the incident of February 26, 1980, at the Crystal River facility, the NRC staff held meetings with the Licensees, other operating licensees with Babcock and Wilcox (B&W) reactor systems, and B&W. The meetings were held in Bethesda, Maryland on March 4,17 and 18,1980. These meetings resulted in the development of three licensee coninitments.
l 1.
Actions which' will allow the operator to cope with various combinations of loss of instrumentaticn and control functions.
This inclu' des changes in (A) equipment and control systems to give clear indications of functions which are lost or unreliable; (B) procedures and training to assure posi-tive and safe manual response by the operator in the event that competent instruments are unavailable.
\\
gj 2.
Determination of the effects of various combinations of loss of instru-mentation and control functions by design review analysis and verification by test.
3.
Correction of electrical deficiencies which may allow the power operated relief valve and pressur,zer spray valve to open on non-nuclear instru-mentation power failures, such as, the event which occurred at Crystal River, Unit 3 on February 26, 1980.
TECO confirmed by letter dated March 24, 1980, that it would implement all three actions at its facility within 90 days, or prior to the restart of Davis-Besse, Unit No. I which was scheduled for shutdcwn for maintenance and refueling on April 10, 1980.
The plant subsequently connenced the outage on April 7,1980. The March 24 letter, as supplemented by letter of April 16, 1980, provided the detailed listing of various combinations of loss of instrumentation which constitutes the commitment in Item 1, and I
also provided the specific list of tests which constitutes the commitment in Item 2.
have concluded that timely implementation of these three short term actions, at operating B&W system nuclear power plants is necessary to provide continued assurance of public health and safety.
III The Office of Inspection and Enforcement (IE) issued Bulletin 79-27 following an event at the Oconee Nuclear Station, Unit No. 3, on November 10, 1979 which was similar to the Crystal River incident. This event was described in Information Notice 79-29, dated November 16, 1979, which was sent to these Licensees. These Licensees were requested by IE Bulletin 79-27, dated November 30, 1979, Loss of Non Class I-E Instru-mentation and Control Power Bus During Operation, to review, among other things, busses supplying power to certain instrument and control systems, emergency procedures related to loss of power to such busses and f ailure to certain power supplies.
In accordance with Bulletin 79-27 the Licensees were requested to submit to the Connission the results of their review by February 28, 1980. The Licensees have not met this date.
l
. The responses to IE Bulletin 79-27 must be submitted in order that NRC can determine whether this license should be modified to protect the health and safety of the public.
TECo's letter of April 16, 1980 committed to respond to the Bulletin by May 6,1980.
IV In view of the importance of this matter I have determined that these commit-ments be formalized by order and that the public health, safety and interest require that this Order be made immediately effective.
Accordingly, pursuant to the Atomic Energy Act of 1954, as amended, and the Commission's regulations in 10 CFR Parts 2 and 50, IT IS HEREBY ORDERED, EFFECTIVE IMMEDI ATELY, THAT:
(1) The Licensees, within 90 days or prior to restart after the current refueling outage will implement all three actions provided in Part II of this Order or in the alternative, place and maintain its facility in a cold shutdown or refueling mode of operation.
(2) The Licensees shall submit by May 6,1980 the written responses to IE Bulletin 79-27 to the NRC.
V Any person who has an interest affected by this Order nay request a hearing within twenty-five days of the date of the Order.
Any request for a hearing will not stay the effectiveness of this Order.
Aay request for a hearing shall be submitted to the Director, Office of Nuclear Reactor Regulation, U. S. Nuclear Regulatory Commission, Washington, D. C.
20555, with a copy to the Executive Legal Director at the above address.
If a hearing is r'equested by a person who has an interest affected by this Order, the Commission will issue an Order designating the time and place of any such hearing.
i l
A r
' In the event any person who has an interest affected by this Order requests a hearing as provided above and a hearing is held, the issues to be considered at such a hearing shall be:
(1) Whether the facts set forth in Parts II and III of this Order provide an adequate basis for the actions ordered, and (2) Whether the Licensees should perform the actions required by Part IV of this Order in accordance with the schedule stated therein.
Operation of the facility on terms consistent with this Order is not stayed by the pendency of any proceedings on the Order.
FOR THE NUCLEAR REGULATORY COMMISSION lr TNf Harold R. Denton, Director Office of Nuclear Reactor Regulation Dated at Bethesda, Maryland this 21stday of April 1980.
