RE folks:

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?
