DPR-51' thterials Type:
Type of order:
Confirmatory order Issue Date:
June 2, 1979 Reason for Order: In the course of authorize.d 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 l
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 pos'ition that would
'. defeat emergency feensater.
The plant was in a hot shutdown condition preparing for startup and the operators apparently took this ac,; ion because pumping of emergency snssilq(:
feedwater for thi.s 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.
The licensee Vice President agreed on 6/2/79 in a telcon to immediately proceed to a cold' shutdown condition and it was ordered that the licensee remain in a cold I
shutdown condition and not restart until the Act. Dir. of IE 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 oparation; (2) the licensee shall evaluate existing procedures Muhu 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 7'
any procedures.
