Attachment to Monthly Operating Report for November, 1983 PEACH BOTTOM ATOMIC POWER STATION NAREATIVE SUPTARY OF OPERATING EXPERIENCES November, 1983 Unit 2 Unit 2 remained shutdown for the entire month of November for inspection of primary system piping welds and the application of weld repairs on the reactor recirculation system and shutdown cooling system.
On November 2, the E-1 diesel generator was out-of-service for repair of an oil leak.
On November 15, an unusual event was declared when a ventilation stack radioactive release of 31 of Tech Specs occurred.
The release occurred as a result of fuel pin puncturing work by General Electric in the f ue3 pool.
A previous occurrence on Unit 3 had resulted in a change to the procedures which resulted in some reduction in the release.
All such work has been halted until a signi ficantly better method can be found.
On November 25, Unit 2 Reactor Hydrostatic Testing was performed.
The unit ended the report period with final preparations for startup.
NRC authorization for plant restart was issued on November 30th.
Unit 3 The unit began the month at full power.
Reactor power was reduced to 770 MWe on November 1 for a control - rod adjustment.
The unit was returned to full power on November 3.
On November 10, the 3C main steam line radiation monitor failed causing a half scram and a half Group I isolation; the radiation monitor was returned to service that same morning.
Reactor power was reduced to 650 MWe on November 11 for a control rod adjustment.
The unit was returned to full power on November.13.
RCIC was taken out-of-service on November 14 to. repair the turbine trip / throttle valve and returned to service three days later.
On November 17, the unit was shut down for replacement of 71E main steam line relief valve due to acoustic leak indication.
During this shutdown, at 16.5 per cent power, an automatic scram occurred on high water level in the scram discharge instrument volume as a result of rapid manual scrarming of individual control rods.
The relief valve was replaced and startup began on November 20.
Reactor power was reduced to 600 MWe on November 24 for a control _ rod adjustment.
The unit achieved full power on November 26.
