SUBJECT:
COMANCHE PEAK STEAM ELECTRIC STATION (CPSES) - UNITS 1 & 2 DOCKET NOS. 50-445 AND 50-446 IN 92-18, POTENTIAL FOR LOSS OF REMOTE SHUTOOWN CAPABILITY DURING A CONTROL ROOM FIRE Gentlemen:
The subject of motor-operated valve (MOV) hot shorts was discussed during the Unit 2 Fire Protection Inspection status meeting with the NRC on December 17, 1992. Although TU Electric considers this scenario to have an extremely low probability, TU Electric committed to implement design changes in the control circuits of the affected MOVs (as required) similar to Figures 5 and 6 of the subject NRC Notice.
Per our discussions with the Staff, TU Electric is committing to implement these hardware modifications prior to startup from the first refueling outage for Unit 2 and prior to startup from the third refueling cutage for Unit 1.
Sincerely, Eq
