These breaker cubicles provide power and control function   s for Train A and B emergency diesel generator room supply fan motors DCGM01A and DCGM01B, respectively. Due to breaker coordination issues, DCP 014209 will modify the power supply to supply 480 VAC power to the diesel generator room supply fan motors DCGM01A and DCGM01B directly from new load center breakers NG0308 and NG0408, respectively. Breakers NG0308 and NG0408 will supply power to the fan control functions within NG03DBF6 and NG04DBF6, respectively.

1.

Purpose:

DECP 020720 is relocating the SA075A MSFIS Panel from NK05119 to NK05103. This CCN is to update the coordination that is outlined in Appendix 3 of XX-E-013 to accurately reflect the current system configuration.

2. Results, Conclusion, Margins, and Recommendations:
a. Results and Conclusions

The changes proposed by this CCN is to update the coordination that is outlined in Appendix 3 of XX-E-013 to accurately reflect the current system configuration. These changes do not change the results of the base calculation.

b. Margins

The changes proposed under this CCN do not adversely impact the results of the base calculation.

These changes are acceptable.

c. Recommendations

There are no recommendations as a result of this CCN because this CCN does no adversely impact the results of the base calculation.

3. Impact on Outstanding CCNs:

x XX-E-013-004-CN001 - [VOID] - There is no impact on this calculation.

x XX-E-013-004-CN002 - [FINAL] - DCP 014209 removes the HMCP breakers from MCC cubicles NG03DBF6 and NG04DBF6, which were added as PFSSD components in CCN XX-E-013-002-CN014 per DCP 13800.

These breaker cubicles provide power and control function s for Train A and B emergency diesel generator room supply fan motors DCGM01A and DCGM01B, respectively. Due to breaker coordination issues, DCP 014209 will modify the power supply to supply 480 VAC power to the diesel generator room supply fan motors DCGM01A and DCGM01B directly from new load center breakers NG0308 and NG0408, respectively. Breakers NG0308 and NG0408 will supply power to the fan control functions within NG03DBF6 and NG04DBF6, respectively.

Therefore, MCC cubicles NG03DBF6 and NG04DBF6 will remain as PFSSD components. The changes per this update do not impact the evaluation performed by this calculation.

x XX-E-013-004-CN003 - [COMMITTED] - Change Package 014658 is replacing cable from EDGs speed signal generators to the EDGs speed switches. Appendices 1, 2 and 3 are updated to reflect these changes. The changes per this update do not impact the evaluation performed by this calculation.

x XX-E-013-004-CN004 - [FINAL] - CP 015070 is changing the 120VAC source from system NG to NN for the control room a/c unit inlet and exhaust dampers GKHZ 0029A/B (Train A) & GKHZ0040A/B (Train B). The changes per this update do not impact the evaluation performed by this calculation.

x XX-E-013-004-CN005 - [SUPERSEDED] - There is no impact on this calculation.

x XX-E-013-004-CN006 - [FINAL] - CP 012513 is replacin g XNB02, and the change impacts the PFSSD components for XNB02. The changes per this update do not impact the evaluation performed by this calculation.

x XX-E-013-004-CN007 - [FINAL] - DCP 020021 is replacing XNB 01, and the new transformer will have a Load Tap Changer (LTC) to control the voltage supplied to 4.16kV bus NB01 even if the 13.8 kV input voltage level changes. The DCP is also replacing/deleting relays in the MA104F panel, and the relays are addressed by XX-E-013. The changes per this update do not impact the evaluation performed by this calculation.

Base Calc. No. Rev. No. Sequence No x XX-E-013-004-CN008 - [FINAL] - CP 013324 replaces the analog-based Westinghouse 7300 Nuclear Steam Supply System (NSSS) with a digital Emerson Ovation Distributed Control System (DCS). The changes per this update do not impact the evaluation performed by this calculation.

x XX-E-013-004-CN009 - [COMMITTED] - This change incorp orates changes per CP 020292 (Substation Transformers NO. 8, 9, 10 & 11 and Breakers Replacement R25) that removes breakers switchyard breakers 13-8 and 13-48 and replaces them with new switchyard breakers 13-49 and 13-50, respectively. The changes per this update do not impact the evaluation performed by this calculation.

x XX-E-013-004-CN010 - [FINAL] - This change relocates the power supply to SA075B panel from NK05423 to NK05403. The changes per this update do not impact the evaluation performed by this calculation change notice.

x XX-E-013-004-CN011 - [COMMITTED] - CP 015000 replaces th e startup transformer XMR01 and replacing several components from Phase Differential Relay, along with the Neutral Ground Relay, while eliminating the Deluge Relay AR7, and the fault pressure relay 463X-2/T2. The changes per this update do not impact the evaluation performed by this calculation.

4. Assumptions and Input:

None

5. Methodology and Computations:

None

6. Affected Pages:

Appendix 3 pages 3, 4, 14, 100, 122 need to be revised per attached markup.
