Public Service Electric and Gas' Salem - Hope Creek facility near Hancocks Bridge, New Jersey. Salem, in the foreground, has 2 Westinghouse 4 Loop PWR units. In the background is the single General Electric BWR-4 Hope Creek unit.

Salem 1 and 2

A number of simplified diagrams illustrate the the design of each Salem pressurized water reactor unit (courtesy Westinghouse)

In each reactor, 193 fuel assemblies of the 17x17 design are used with 264 fuel rods per assembly. The containment is a large steel structure rated at 47 psi pressure.Each reactor coolant loop has 1 U-tube vertical steam generator and 1 reactor coolant pump. Each unit has a pressurizer connected to one of the 4 loops. Normal makeup water is provided by 1 of 3 Chemical and Volume Control System charging pumps. A smaller positive displacement pump is rated at 98 gpm and 2510 psi. The 2 centrifugal charging pumps, each rated at 150 gpm and 2510 psi double as the emergency high head safety injection system pumps. Their shutoff head is 2565 psi.

On the non-radioactive secondary side of the steam generators, condensate-feedwater is supplied by 3 condensate pumps (693 psi) and 2 turbine-driven feedwater pumps which move the water from the condenser to the steam generators. Pressure and temperature are raised from vacuum and 90F to 1100 psi and 425 F.

Emergency equipment for each unit include:

• 2 Low head safety injection (Residual Heat Removal) pumps rated at 3000 gpm @ 155 psid with a shutoff head of 165 psig supplied from the 400,000 gallon Refueling Water Storage Tank.
• 2 Intermediate Head safety injection pumps rated at 425 gpm @ 2500 ft with a shutoff head of 1500 ft,
• 2 High head safety injection pumps rated at 415 gpm @ 1250 psid with a shutoff head of 1535 psid supplied first from 1 of 2 8000 gallon Boric Acid Makeup Tanks, and then from from the 400,000 gallon Refueling Water Storage Tank.

• 1 Accumulator containing 10,000 gallons and pressurized to about 750 psi is connected to each reactor coolant loop.
• 2 motor-driven (440 gpm @ 1300 psi) and 1 turbine-driven (880 gpm @ 1550 psi) Auxiliary Feedwater pumps supplied from theAuxiliary Feed Storage Tank or other sources listed below.
• 3 Diesel generators (only 2 needed) for each unit; Salem is unusual in that a 40 MWe gas turbine can act as the emergency generator in event of a station blackouT.

Emergency water sources include:

• Auxiliary Feed Storage Tank ----220,000 gals
  Demineralized Water Storage Tank---500,000 gals
  Demineralized Water Storage Tank---500,000 gals
  Fire Protection and Domestic Water Storage Tank---350,000 gals
  Fire Protection and Domestic Water Storage Tank---350,000 gals
  Service Water System (Spoolpieces must be connected for this to be a source of water)
