SUBJECT:
SHUTDOWN IN EXCESS OF 72 HOURS On february 2,1992, at 6:09 a.m. (EST), Brunswick Unit 2 experienced a reactor scram from 79 percent power during main turbine control valve (CV) testing. Just prior to the event, testing .of CV-2 had* gener~ated a half scram on Channel 81 due to the expected trip / actuation of CV-2's associated electro hydraulic control (EHC) fluid pressure switch.
- Upon releasing the CV-2 test
- push button, the associated CV-1 EHC fluid pressure switch momentarily tr.ipped/ actuated, generating a half scram on Channel A1. As the half a full reactor scram resulted. All safety scras systems on. functioned Channel B1 a.s had required, not yet andbeen the ugreset,l(presently remains in the hot shutdown condition. *
+ . -
'icensee' actions towards; determining / correcting the root cause of the scram have been 1cused .on the EHC . system. To date, in situ testing of the associated CV-1
.<l0 fluid pressure switch has been indeterminate. Additionally EHC fluid in-leukage was discovered in bcth nitrogen accumulators on the EHC system. Prior to restart the in-leakage problem on botn;EHC system nitrogen accumulatcrs will be correctt.d, Ek fluid pressure switches on all four CVs will be replaced, and the EHC system will be tested to ensure the initiating problem has been corrected.
Other work activities in progress include repairs to the 2A reactor feed pump (which bound up subsequent to the event) and copecting identified feedwater heater related hanger / support deficiencies.
Region I'I and the resit.ent inspectors have, and will continue to followup on the event and the work activities in progress.
The.NRC received initial. notification 'of this event by Telephone call to the Headquarters )
