79 9 UNITED STATES OF AMERICA NUCLEAR REGULATORY COMMISSION MT,W; In the Matter of
)
ARKANSAS POWER AND LIGHT COMPANY Docket No. 50-313 (Arkansas Nuclear One - Unit No. 1)
)
ORDER I.
The Arkansas Power and Light Company (the " licensee") is the holder of Facility Operating License No. DPR-51 (the " license") which authorizes operation of the Arkansas Nuclear One - Unit No.1 (the " facility") at steady reactor power levels not in excess of 2568 megawatts thermal (rated power).
The license was issued on May 21, 1974, and has an expiration date of December 6, 2008.
The facility consists of a Babcock and Wilcox designed pressurized water reactor (PWR), located at the licensee's site in Pope County, Arkansas.
II.
In the course of authorized return to power from a cold shutdown condition, operators deviated from the established but apparently deficient procedure for routine surveillance test of the check valves in the main feedwater system.
The procedure was deficient because it did not specify that operators bypass and return the emergency feedwater system to normal.
The plant staff bypassed the controls to automatically start EFS by placing the control switches in a position that would defeat emergency feedwater.
The plant was in a hot shutdown condition preparing for startup and the operators apparently took this action because pumping of emergency feedwater for this test would be undesirable and unnecessary.
Lacking a procedural requirement to return these switches to normal there was no assurance that emergency feedwater would be provided automatically, if needed, later during power operation.
In view of these circumstances, which were discovered by an NRC 2237 264 7906250;
inspector, the facility should be temporarily placed in a cold shutdown condition.
In a telephone conversation on June 2,1979, the licensee Vice President, Mr.
William Cavanaugh, III, agreed to immediately proceed to a cold shutdown condition and to remain in that condition until confirmation by the Acting Director, Office of Inspection and Enforcement, that the conditions for startup set out in Part III below, have been satisfied.
It is desirable to 'confim by order the licensee's agreement to proceed to cold shutdown.
III.
In light of Part II above, IT IS HEREBY ORDERED THAT, pursuant to 10 CFR Parts 2 and 50, the licensee shall proceed to, and remain in, a' cold shutdown condition and shall not restart until the Acting Director, Office of Inspection and Enforcement, has confirmed in writing, that the following actions have been satisfactorily accomplished:
(1) the licensee shall evaluate and modify as appropriate
' its methods for the development, review and approval of procedures for all modes of plant operation; (2) the licensee shall evaluate existing procedures to assure that such procedures include all actions necessary for safety; and, (3) the licensee shall take appropriate steps to assure that all plant personnel adhere to approved procedures and do not add unauthorized steps to any procedures.
