Subject:
FAILURE OF 4 INCH FEEDWATER REGULATING BYPASS VALVE During a startup ar 9:15 a.m. on January 6. 1976, a significant flow transient in the feedwater system occurred. As a result, the 4 inch feedwater regulating bypass valve had a valve yoke failure which resulted in the
.,' ejection of the valve stem with a subsequent loss of several hundred -
gallons of high temperature, low activity water and stum th, rough the one inch hole. , , ,
The reactor was shutdown without incident.
. The valve is located in the turbine building condenser bay area and is l in a non-safety related system. The feedwater line has two series check
, valves and a manual valve between the reactor and the failed valve.
As an apparent consequence of the force of the stem ejection, the valve body was reported to have a 360 degree circumferential crack which-does - - -
not appear to be through wall.
There were no personnel injuries or releases to the station or environment
. above regulatory limits. A scheduled refueling outage may be advanced 10 days because of this event.
