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
