The MPS3 COLR has been revised to incorporate the following:

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 by Dominion.

3) The revision to a footnote to indicate that the requirements in COLR Section 2.14 are 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.
