1) Editorial changes to increment the Cycle number from 16 to 17.2) The addition of a footnote to indicate that the SHUTDOWN MARGIN requirements in COLR Sections 2.4.and 2.5 are based on cycle specific analyses performed byDominion.
3) The revision to a footnote to indicate that the requirements in COLR Section 2.14are based on cycle specific analyses performed by Dominion.
4) Cycle 17-specific changes to the W(Z) values.5) Cycle 17-specific changes to the burnup penalties for incore (FQ(Z)) surveillance.

The COLR has been incorporated into the MPS3 Technical Requirements Manual.If you have any questions or require additional information, please contact William D.Bartron at (860) 444-4301.

The specified SMM Alarm Ratio setting ensures that the assumption that an alarm isgenerated at flux doubling in the Boron Dilution Event analysis remains valid. The countrate is displayed on the SMM.2 Limit not applicable during either a THERMAL POWER ramp in excess of 5% ofRATED THERMAL POWER per minute or a THERMAL POWER step in excess of10% of RATED THERMAL POWER.3 Section 2.14 is based on cycle-specific boron dilution analyses performed byDominion.
