l On December 31, 1982, during routine operation, an operator discovered that the low gpressure CO2 storagei tank pressure wac 275 psig, less than the 285 psig required by

~

gthe Technical Specifications.

'the Iow Pressure CO2 System was declared inoperable, anq o,

Action Statement 3.7.10.3a was entered.

Investigation of the problem revealed that g

g, g l the system refrigeration compressor had failed to stop at 295 psig and was still runnirp.

O 6

,, y The compressor was de-energized and the pressure returned to normal. A continuous g

g, g fire watch with backup fire suppression equipment was established in the affected arcaq.
