WOLF CREEK TABLE 9.5E-1 (Sheet 6)IOCFR50 ADDendix R WCGS batteries are served by a battery charger that can be manually connected to the plant emergency ac power supply.The ESW pumphouse also complies.III. G. Fire Protection of Safe Shutdown Capability

1. Fire protection features shall be provided for struc-tures, systems, and components important to safe shutdown.These features shall be capable of limiting fire danger so that: a. One train of systems neces-sary to achieve and maintain hot shutdown conditions from either the control room or emergency control station(s) is free of fire damage; and b. Systems necessary to achieve and maintain cold shut-down from either the control room or emergency control station(s) can be repaired within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.2. Except as provided for in paragraph G.3 of this section, USAR Appendix 9.5B pro-vides an area-by-area analysis of the power block that demonstrates that no single fire can prevent safe shutdown.Redundant trains of sys-tems required to achieve and maintain hot standby are separated by 3-hour-rated fire barriers, or the equivalent provided by III.G.2, or else a diverse means of-pro-viding the safe shut-down capability exists and is unaffected by the fire.For redundant trains of systems required to achieve and maintain cold shutdown that could potentially be affected by Rev. 0/I
