11.9 CONDENSATE STORAGE SYSTEM 11.9.1 Power Generation Objective The power generation objective is to provide condensate for system makeup needs, and to take system "reject" surges.
11.9.2 Power Generation Design Basis The condensate storage system shall provide station system makeup, receive system reject flow, and provide condensate for any continuous service needs and intermittent batch type services.
The total stored design quantity shall be based on the demand requirements during refueling for filling the dryer separator pool and the reactor well.
Two tanks shall be used for reasons of operational flexibility so that a plant shutdown will not be required when one tank is being maintained.
11.9.3 Description The two 275,000 gal condensate storage tanks supply the various station requirements as shown on Figure 11.9-1.
The tanks are of
-'coated carbon steel with all inlet and outlet lines, overflows, vents, and instrument lines located at the tank bottom or toward the tank center to prevent freezing problems.
The condensate storage system also consists of the two condensate transfer pumps, a
jockey
- pump, and associated piping and valves.
The condensate tanks provide the preferred supply to the HPCI and RCIC systems.
The torus water storage provides the backup emergency HPCI and RCIC systems supply.
All other suctions are located above the HPCI and RCIC suctions to provide a 75,000 gal reserve in each tank for these systems.
