CP 15070 is changing the 120VAC source from system NG to NN for the control room A/C unit inlet and exhaust dampers GKHZ0029A/B (Train A) & GKHZ0040A/B (Train B). This is to provide damper function to mitigate a radiological release scenario through the non-operation train with the loss of the EDG. This change is inconsequential to PFSSD. The PFSSD function to support one train of control room A/C cooling is maintained as a single fire scenario will not impact both NN sources. For PFSSD applicability, this will remove distribution panel breakers NG03CLF115 and NG04CLF121 and add fused disconnects NN0121 and NN0422.

TABLE A FOOTNOTE:

The purpose of this column is to enable Wolf Creek to track and trend deficiencies discovered during package verification. IF the design verification question is answered no, THEN he verifier shall mark this box with deficiency type as follows:

Type Description x MPR - Missed procedural requirement. Use this designator if all or part of a process step was not performed.

x TEV - Technical Error by Vendor. Use this designator if the discrepancy was caused by the actions of a Vendor. If the discrepancy was caused by misinformation supplied by Wolf Creek, use the next designator.

x TEWC - Technical Error by Wolf Creek. Use this designator if the discrepancy was caused by Wolf Creek personnel.

IF the design verification question is answered yes but could be significantly enhanced by additional or altered information, THEN the verifier shall mark the box as:

x DE - Document enhancement opportunity
