Byron and
Braidwood have combined the 30% and 50% flux maps. Actually, we have
several conditional statepoints, but we typically only perform a flux map at
~41% and ~100%. If we had BEACON inoperable and performed the first
flux map < 40%, we would perform another flux map < 80%
(rare).
We don't
stabilize at all because BEACON handles the Xenon build-in and provides the
"reference" values for the conditions that
exist.

Subject: Power Ascension Flux Mapping for
Westinghouse PWRs
I
would greatly appreciate it if you could answer the following three questions
for your Westinghouse PWRs:
(1)
Do you perform a flux map at ~30% RTP and ~50% RTP?
(2)
How long do you stabilize before collecting MIDS data at these plateaus?
(3)
What is the basis for the stabilization
times?
Best
Regards,
Bill
