Subject:
Umerick Generating Station, Unit I lasuance of Revision 3 of the Core Operating Umits Report for Reload 5, Cycle 6 Gentlemen:
Enclosed is a copy of the Core Operating Umits Report (COLR), Revision 3, for Umerick Generating Station (LGS), Unit 1 Cycle 6, Reload 5. This COLR provides the cycle-specific parameter limits for: Maximum Average Planar Unear Heat Generation Rate (MAPLHGR); Minimum Critical Power Ratio (MCPR); ARTS MCPR thermallimit adjustments and multipliers; ARTS MAPLHGR thermallimit multipliers; Rod Block Monitor (RBM) setpoints; MAPLHGR single loop operation (SLO) reduction factor; Unear Heat Generation Rate (LHGR); Turbine Bypass Valve parameters; Recirculation Pump Motor Generator (MG) Set Scoop Tube Stops; and Reactor Coolant System Recirculation Flow Upscale Trips for LGS, Unit 1, Cycle 6, Reload 5.
These values have been determined using NRC4pproved methodology and are established such that all applicable limits of the plant safety analysis are met, j
Revision 3 of the LGS Unit 1 Cycle 6 COLR addresses three issues related to thermal limits monitoring for Cycle 6: (a) validity of the original reload licensing analyses following the August,1995 core reconfiguration, (b) incorporation of revised MAPLHGR limits to improve thermal margin, and (c) deletion of the previous revision of this document (i.e., Revision 2), which was approved, but not issued, nor implemented.
This COLR Revision is being submitted to the NRC in accordance with LGS, Unit 1 Technical Specifications (TS) Section 6.9.1.12.
