PLANT SYSTEMS BASES ULTIMATE HEAT SINK (Continued)

A redundant makeup system using deep wells as a water source is designed to withstand design basis tornado events, river flood events, and design basis seismic events combined with low Rock River flow or level.

The second redundant system is the essential service water makeup system that uses the Rock River as a water source.

It is designed to withstand all design basis natural phenomena events and combinations of events except for seismic events during low Rock River flow rates, design basis tornado events and river flood events.

Each essential service water makeup pump is powered by a diesel engine with a fuel supply adequate for approximately 3 days of operation.

Achievement of the design basis 30-day operation is dependent upon successful implementation of plant procedures to replenish the fuel supply following design basis events.

With water in the cooling tower basin at an initial temperature less than or equal to 80 F, shutdown can be achieved, for meteorological conditions fol-lowing a design basis tornado, without operation of the cooling tower fans and without the temperature of the water discharged from the essential service water pump exceeding 110 F, the maximum acceptable temperature for components and systems cooled by the essential cooling water system.

Achievement of the design function of the UHS during more severe meteorological conditions, or following a design basis LOCA, requires operation of two cooling tower fans to maintair, the discharge temperature less than or equal to 110 F.

Plant procedures ensure that the fans are started and controlled by operator action to maintain a dis-charge temperature of less than 110 F.

With all 4 Unit 1 designated cooling tower fans running, either redundant ultimate heat sink train is capable of removing the design bases LOCA heat load without exceeding a pump discharge temperature of 98 F.

3/4.7.6 CONTROL ROOM VENTILATION SYSTEM The OPERABILITY of the Control Ronm Ventilation System ensures that: (1) the ambient air temperature does not exceed the allowable temperature for continuous duty rating for the equipment and instrumentation cooled by this system, and (2) the control room will remain habitable for operations personnel during and following all credible' accident conditions.

Operation of the system with the heaters operating for at least 10 continuous hours in a 31-day period is sufficient to reduce the buildup of moisture on the adsorbers and HEPA filters.
