FENOC PWRs (Beaver Valley and Davis-Besse) currently utilize the following:
SL4
Unplanned Reactivity Change Caused by Equipment Problem or Personnel Error · Reactor Power Change < 0.5% RTP When >5% RTP Reactivity Change < 100 pcm (based on 10 deg temp change) When ≤ 5% RTP
SL3
Unplanned Reactivity Change Caused by Equipment Problem or Personnel Error · Reactor Power Change ≥ 0.5% RTP When > 5% RTP Reactivity Change ≥ 150 pcm (based on 10 deg temp change) When ≤ 5% RTP
We need to revise to 150 pcm for the cut-off. Based on results of this survey, we may also revise, or this may be something for the PWROG Reactivity Management Task Team to address...

What values of "x" are plants using for example criteria 3.9 and 4.6 in the PWR Reactivity Management Performance Indicator PI?
