WSES-FSAR-UNIT-3 j , 9.2.7.2 System Descriptica l

The Turbine Closed Cooling Water. System is a closed loop system which uses desineralized water to remove heat from the turbine accessories and other components in the power cycle. System component design data are given in Table 9.2-13. A schematic diagram of this system is shown in Figure 9.2-7.

The water is circulated by two turbine cooling water pumps, and the heat removed via two turbine cooling water heat exchangers is .trans-ferred to the Circulating Water System. Turbine cooling water cir-culates. through the shell side of the heat exchangers.

A surge tank, open to the atmosphere, is connected to the Turbine Closed Cooling Water System. The tank level is automatically controlled by level

- switches and a level control valve, with makeup provided from the conden-sate storage tank. A main control room alara is initiated on both high and low water 1cvels.

A commercial corrosion inhibitor is used to maintain proper corrosion protection for the Turbine Cooling System. The turbine cooling water chemistry is sampled periodically, and inhibitor added from the chemical feed tank when needed to maintain a desired concentration.

The plant components cooled by the Turbine Closed Cooling Water System include:-

a) turbine lube-oil cooler, '

b) turbine electrohydraulic fluid coolers, c) hydrogen seal-oil coolers, d) generator hydrogen coolers, c) generator stator water coolers, f) exciter cooling units, g) heater drain pump seal and stuffing box coolers, h) steam generator feed pump turbine coolers,

1) condensate pump motor-bearing coolera, j) condenser vacuum pumps heat exchangers,

- k) instrument and station air compressor jackets,

1) isolated phase bus heat exchangers.

Component a,b,d,e, and h listed above, are provided with automatic temperature control valves in the cooler outlet piping.
