SUBJECT:
REVISION TO TECHNICAL SPECIFICATION -
MBoyle AWang REPOSITIONING FLOW CONTROL VALVE - RH-FCV-796 IN THE RESIDUAL HEAT REMOVAL SYSTEM Re:
Haddam Neck Plant The Commission has issued the enclosed Amendment No. 88 to Facility
. Operating License No. DPR-61 for the Haddam Neck Plant. This amendment is in response to your application dated December 17, 1986, as supple-mented December 19, 1986.
The amendment would establish a plant configuration which assures that adequate cooling will be maintained during sump recirculation while satis-fying single failure requirements. That configuration involves reposi-tioning and locking flow control valve RH-FCV-796 in the Residual Heat Removal (RHR) system in the partially open position and initiating, under prescribed conditions, charging system flow to assure proper flow distribution and pump operability in the event the specific break at issue were to occur.
The staff has reviewed the circumstances associated with your request and has concluded that this change is needed to avoid the requirement to derate or shutdown. Therefore, in accordance with 10 CFR 50.91(a)(5), justification for the issuance of an emergency technical specification existed.
A Notice of Consideration of Issuance of Amendment to License will be included in the Comission's biweekly Federal Register notices. A copy of our related Safety Evaluation is enclosed.
