Subject: [Pwrrm] CVCS return to
service
Following a refueling outage, the return to service operating procedure of the
Chemical Volume Control System Blender has Operations and I&C set up the
blender to obtain the correct boron concentration. The potentiometers are
set and FCVs adjusted to obtain near the set point, best as possible. However,
there are no acceptance values in the procedure. It has been a judgement call
by the Operations staff. For other sites, what is the criteria and/or process
for the return to service of the blender? If there are acceptance values, what
are they?
Thank you.
