The proposed amendment will increase the unit's licensed core thermal power level from 2700 megawatts thermal (MWt) to 3020 MWt and revise the Renewed Facility Operating License and TS to support operation at this increased core thermal power level. This represents an approximate increase of 11.85% and is therefore considered an Extended Power Uprate (EPU).During the course of their review and as provided in the May 12, 2011 electronic mail[Reference 2], NRC staff in the Reactor Systems Branch informally requested information related to steam generator tube rupture steam release and margin to overfill to support their review of the EPU LAR.
