GPERATIONS

SUMMARY

- SEPTEMBER 1978 (

At the beginning of the report period, the unit was operating at approximately

69% power in an end of cycle reactivity coastdown with control rod withdrawal i 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

( R0 #78-20 occurred on September 17 when two (2) intermediate range I

flux monitors became inoperable in the refuel mode. -l
