SALEM UNIT NO. 2 OPERATIONS
SUMMARY
REPORT JUNE 1984 Unit No. 2 began the month shutdown in order to replace 21SJ16 and 22SJ16 valves.
These valves, which are in the ECCS flow path, were considered inoperable after radiographs indicated the valve plug and stem orientation were not proper.
Inspection of the valves after their. removal revealed that the weld that holds the disk nut to the disk was missing.
The Unit remained in Mode 5 until June 5, 1984 when plant heatup commenced.
No load pressure and temperature of 2235 psig and 547*F was reached on June 6, 1984.
A plant cooldown to approximately 367"F was initiated on June 7, 1984 to facilitate changeout of No. 23 CFCU motor.
No. 23 CFCU motor failed to start in slow speed during surveillance testing thereby requiring its repair or replacement.
No. 23 CFCU was subsequently replaced with No. 14 CFCU, however it too failed to start in slow speed.
No. 22 CFCU has been placed in the No. 23 CFCU location.
No. 12 CFCU has been placed in the No. 22 CFCU location.
The apparent cause of the CFCU failures to start in slow speed was misalignment of the rotor to stator air gap.
The plant recommenced heatup on June 13, 1984.
