limited by the' Technical Specifications.
On September 4,1978, a turbine trip and reactor scram occurred when the feedwater master controller failed due to a ground in the level recorder.
The unit was returned to service on September 5 following repairs to the feedwater controls.
l i
On September 15, 1978, the unit was shut down to commence refueling operations.
Refueling continues at the end of this report period.
i 1
Six (6) Reportable Occurrences were identified during the report period:
d R0 #78-15 occurred during the post scram period on September 4 when both isolation condensers isolated by actuation of their line break sensors.
R0 #78-16 was identified on September 14 and involves failure to inspect two (2) hydraulic shock and sway arrestors as required.
R0 #78-17 occurred on September 14 when the closed position torque switch on isolation condenser valve V-14-37. failed, tr,ipping.the. motor overloads.
R0 #78-18 occurred on September 16 when three (3) main steam isolation
(
valves failed to meet the maximum allowable leakage rate.
l RO #78-19 occurred on September 15 when two (2) reactor building to torus vacuum breaker valves malfunctioned during operability testing.
l
(
I R0 #78-20 occurred on September 17 when two (2) intermediate range flux monitors became inoperable in the refuel mode.
