STEAM GENERATOR DESCRIPTION In the Prescurized Water Reactor (PWP) system, the steam gun-erators isolate the radioactive reactor coolant from the non-radioactive steam cycle, and serve as the heat exchanger between the two systems.

The Westinghouse steam generators are vertical U-tube natural circulation evaporators and consist of two sections:

1) a heat exchange section with reactor coolant channel head, tube sheet and tubing, and 2) a steam separator section which includes the feedwater ring.

The heat exchange section is a vertical shell and U-tube heat exchanger.

The Indian Point Unit 2 steam generators (See figure 1) are Westinghouse Series "44",

with a total heat transfer surface of approximately 44,000 square feet.

The heat transfer tubes are Inconel 600 (ASME SB 163, Alloy UNS N06600) and the support plates are curbon steel (ASME 3A 285).

There are four steam generators with 3,260 tubes and 6 support plates each.

The tubes have a design outside diameter of 875 mils and wall thickness of 50 mils.

During operation, high temperature, high pressure reactor cool-ant flows from the Reactor Vessel to the inlet side of the channel head at the bottom of the steam generator by way of the hot leg, enters through the inlet nozzle, flows through the
