Equipment, capability pools

The IC/PCC pool has an installed capacity that provides at least 72 hours of reactor decay heat removal capability. The heat rejection process can be continued indefinitely by replenishing the IC/PCC pool inventory. The ICS passively removes sensible and core decay heat from the reactor (i.e., heat transfer from the IC tubes to the surrounding IC/PCC pool water is accomplished by natural convection, and no forced circulation equipment is required) when the normal heat removal system is unavailable. 

The design of wet storage facilities shall include the capability to purify the bulk of the pool water. The controlled removal of dissolved and suspended radioactive materials might be necessary to limit radiation fields at the surface of the pool. The provision of equipment to clean the walls of the pool liner should be provided for periodically removing radioactive deposits and sludges from these surfaces.
