The MPS3 COLR has been revised to incorporate the following:

  • Editorial changes to increment the cycle number from 14 to 15.
  • Revision of the MODE 5 (with RCS loops filled) shutdown margin requirements in Figure 4 to support Cycle 15 conditions.
  • Cycle 15-specific changes to the W(Z) values in Tables 1 through 3.
  • Revision of the burnup penalties for incore measurements in Table 4 to support Cycle 15 conditions.
  • Editorial change to Reference 3.6 to correct a typographical error.

" Editorial change to the title name of Table 4 on Pages 8.1-3 and 8.1-24.

The COLR has been incorporated into the MPS3 Technical Requirements Manual.

2 Section 2.14 was prepared by Dominion based on boron dilution analyses performed by Westinghouse.

3 This boron concentration bounds the condition of keff _<0.95 (all rods in less the most reactive two rods) and subcriticality (keff_1l.0 with all rods out).
