1.0 Purpose and Scope Wolf Creek is performing a systematic replacement of their large oil-filled transformers to address aging concerns and to implement design improvements in support of long term station operation. The first transformer to be replaced is ESF transformer XNB01.
DCP 020021 is replacing XNB01 and the new transformer will have a Load Tap Changer {L TC) 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 MA 104F panel and the relays are addressed by XX-E-013. The purpose of this calculation is to document the impact on Wolf Creek calculation XX-E-013 due to these changes. This calculation is non-safety related per the ENERCON requirements. The Wolf Creek update will be considered "special scope " per the site requirements.
2.0 Summary of Results and Conclusions Wolf Creek calculation XX-E-013 does not have any computations. It is a document used to identify the components required to support the Post Fire Safe Shutdown (PFSSD) functions. Based on the results of this ca lcu lation the addition of the L TC controls will not impact the PFSSD function of XNB01. Two overcurrent relays (287/T1 Phase Band Phase C) are removed from the calculation (287/T1 Phase A is replaced with one new relay to monitor all three phases). Also, components 263-1/T1, 263X-1/T1, 263-2/T1 and 263X-2/T1 are removed from the ca lculation. New fault pressure trip relays 263FP K4A and 263FP K4B are added because they provide a trip input for breaker NB00112 (XNB01 input breaker to NB01 ). Cable 15NBK16AA supplies 125VDC to the sudden pressure monitor that contains the two relays at XNB01. Failure of this cable does not cause the relays to

change state and cause a loss of power to XNB01. Therefore, cable 15NBK16AA is not a PSFFD related cable. Drawing E-1F9425 impacted by this change and will be revised by DCP 020021 via WIP-E-1 F9425-002-A-1.
The proposed changes to XX-E-013 as a result of DCP 020021 are acceptable.

Reviews of existing change notices against XX-E-013 were performed to determine if any of the documents impact the changes being performed by DCP 020021. Results are as follows:
- XX-E-013-004-CN001 - VOID
- XX-E-013-004-CN002 - FINAL - DCP 14209 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 functions for Train A and B emergency diesel generator room supply fan motors DCGM01A and DCGM01 B, respectively. Due to breaker coordination issues, DCP 14209 will modify the power supply to supply 480 VAC power to the diesel generator room supply fan motors DCGM01A and DCGM01 B 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.
- XX-E-013-004-CN003 - COMMITTED - Change Package 14658 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.
- XX-E-013-004-CN004 - FINAL - CP 15070 is changing the 120VAC source from system NG to NN for the control room ale unit inlet and exhaust dampers GKHZ0029A/B (Train A) & GKHZ0040A/B (Train B).

The changes per this update do not impact the evaluation performed by this calculation.
6.0 Methodology This calculation is a tabulation of cables and components that are required to support the PFSSD power sources and functions. XNB01 is a power source that is required to support the PFSSD functions. The impact of the L TC controls on the PFSSD power supply function was reviewed and determined to not impact the PFSSD power supply function of XNB01. PFSSD components associated with XNB01 are listed in calculation XX-E-013. Some of the components are being removed by DCP 020021. The calculation was reviewed and components 287/T1(B) and 287/T1(C) are removed from the plant and will be removed from the calculation. Relay 287/T1(A) is changed to 287/T1(A,B,C} because the new digital relay monitors all three phases. Fault pressure monitors 263-1/T1 and 263-2/T1 are being removed from the plant and will be removed from the calculation. Auxiliary relays 263X-1/T1 and 263X-2/T1 are being disconnected/
"abandoned-in-place " and will be removed from the calculation. A new sudden pressure monitor at XNB01 contains trip relays that are used to trip the NB00112 breaker on a fault pressure signal, 263FP relays K4A and K4B. These relays will be added to the calculation. The changes to the relays also impact drawing E-1 F9425. This drawing update will be addressed in DCP 020021 via WIP-E-1 F9425-002-A-1. PK4115 via cable 15NBK16AA supplies 125VDC to the sudden pressure monitor. Failure of this power source or cable does not cause the relays to change state and loss of XNB01. Therefore, PK4115 and cable 15NBK16AA are not required for PFSSD.

PA0210 is included in the PFSSD design because PA021 O control section provides control power for PA02. No PFSSD loads other than PA02 control power are supplied by PA0210.
Off-site power availability requires that off-site power cables and cables associated with XNB01 and XNB02 protective relays remain free of fire damage. The power cables are associated with the circuit breakers in the preceding table. Off-site protective relays and potential transformers required for PFSSD are identified in Appendix 4 and Appendix 3.
The above discussion addresses safety-related power required for post fire safe shutdown. A limited number of components derive their power from non-safety related busses (PA01 and PA02). The non-safety related po wer is normally supplied from the unit auxiliary transformer (XMR02). On a failure of XMR02 or the power to XMR02, a fast bus transfer to the start-up transformer (XMR01) occurs. The power path from XMR02 is not included in the PFSSD design because the XMR01 power path is in the PFSSD design. Other than 480V MCCs, there are no other non-safety related PFSSD loads powered from PA01 and PA02. Controls required for off-site and on-site power are identified in Appendix 3.
Forced cooling of ESF transformers XNB01 and XNB02 is not required for PFSSD. Each transformer has a self cooled rating of 12 MVA and a forced air cooled rating of 16 MVA. The maximum design basis accident (DBA) load is approximate ly 6 MW which equates to 6 MVA assuming a power factor of 1 (actua l power factor is between 0.8 and 1.0). Therefore, there is a 100% margin for the OBA loading for the self-cooled rating. PFSSD loading would be equal to or less than the DBA rating since some of the DBA loads are not credited for PFSSD (e.g. containment spray pumps and safety injection pumps). Therefore, there is adequate justification for not including ESF transformer coo ling in the PFSSD analysi
Lo wer medium voltage - 4.16KV components and rela s required for PFSSD are identified in Appendix 4 and Appendix 3.
An evaluation of the potential for a fire-induced lo of off-site power is con tain ed in Appendix 2. This evaluation identified the p lant locations where a fire initiate oss of off-site power (loss of non-safety related power ) could occur.
Low Vo ltage System - 480V
XNB01 has a Load Tap Changer {LTC) that is used to maintain a set voltage level on the NB01 bus even though voltage level changes on the 13.8kV switchyard supply voltage may occur. This function is local to the transformer. The power for the L TC controller is supplied from the 480VAC power supply to the transformer for auxiliary loads, such as fans. When operated in a "fixed tap" position (fixed tap setting by Operations) the transformer functions as a standard step down transformer and there are no new failure modes. When placed in the "automatic" mode of operation, the L TC controller monitors the 13.8 kV input and adjusts the tap changer position to maintain the NB01 voltage level at a set level. A failure of the main L TC controller would result in the L TC controls being shifted to the backup L TC controller and the Control Room being informed of the change via an alarm. A loss of 480VAC power to XNB01 will result in loss of power to the main and backup L TC controllers. This would keep the tap setting at a fixed position (the same as the "fixed tap" operation) and the transformer functions as a standard step down transformer.
Therefore, a loss of power to the L TC controllers will not impact the PFSSD function of XNB01.
