Subject:

Criticality Monitoring Letter I read the NRR letter on criticality monitoring that was copied to us and I have a question, in discussions with our PM and the author, it became clear that when St.

Lucie comes in for an exemption to 70.24, they'll receive it and, in fact, they had one pre-op that wasn't subsumed into the operating license. If this is the case, shouldn't the proposed NOV be a vio of minor safety significance? I looked at the criteria in the {

Enforcement Manual and it seems to fit.

runout. - Since both EFW pumps draw suction through the same pipe. the resulting
