4.7.4 Generator Flush Cycle
(Description of Phases)
The Generator Flush Cycle progresses through the following phases:
a. DEPRESSURIZE
A printout, similar to the following, occurs when the cycle starts:
* GENERATOR 9:25:51 AM
FLUSH START
NOTE: If there is no pressure in the steam generator when the flush
cycle starts, the generator partially heats up to remove the vacuum
from the generator.
The depressurize phase removes pressure from the generator by
flowing it through the jacket and/or door seal(s). If doors are closed,
door seal(s) can be used, which subtracts approximately 20 minutes
from the depressurize phase. The generator pressure switch must
be closed and the jacket temperature must be less than 100°C to
end the phase.
b. OPEN VALVE
Generator drain ball valve opens.
c. DRAIN
