Docket No. 50-289 Mr. R. C. Arnold Senic-Vice President Metropolitan Edison Company 100 Interpace Parkway Parsippany, New Jersey 07054
Dear Mr. Arnold:
SUBJ ECT: REQUEST FOR INFORMATION ON THE EFFECTS OF CERTAIN VALVE LINE-UP PROCEDURAL CHANGES Based upon design review, we have determined that Arkansas 1, Crystal River 3, Oconee 1, 2, and 3, Rancho Seco and Three Mile Island I have two check valves in series with a closed motor operated valve (MOV) to isolate the low pressure safety injection system from the reactor coolant system. We have recently co@leted a study of this configuration (0conee) and its contribution to the risk of core melt. The results show a higher value contribution to the risk of core nelt from a loss of coolant accident outside of containment than previcusly fcund for Surry O! ASH-1400).
We are studing this matter and pursuine interim and permanent resolutions.
The pemanent fix, which is being acdressed as part of the review of your Inservice Testing Program, requires a leak test of the check valves or an equivalent test. The proposed interim resolution seeks to place the check valves under continuous test by requiring that the plant be started up and operated with the MOV open. Before we adopt this temporary fix, we wish to be assured that this interim approach carries no unacceptable adverse safety impact.
We have, in the past, discussed the following questions with members of your staff:
1.
What is the adverse safety impact of starting up the plant with the MOV in the open position?
2.
What is the adverse safety impact of operating the plant with the M0V in the open position?
In order to assess the impact of the proposed MOV position and to allow your comments to be considered prior to our resolution of this issue, kindly submit your response to the two questions above within 45 days of receipt of this letter.
Sincerely, s
Robert W. Reid, Chief 1938 167 Operating aeactors aranch #4 Division of Operating Reactors cc:
