The major pumps used in the Rajasthan Atomic Power Plant type of stations in India are given. The primary heat transport and condenser water pumps are studied in detail. For CANDU reactors, the coolant is pressurized heavy water and the primary heat transport pump operates at a suction pressure of above 1200 psig and at a temperature of 505 deg F. The pump has to be suitable for continuous running for 8000 hrs and the material used for construction should not be impaired due to radiation damage. The pump design should also take into consideration the rate of cooling of about 30 deg C/min. Carbon steel and stainless steel are the materials used for the construction of the pumps. A shaft development program for these pumps is currently being discussed at the Bhabha Atomic Research Center, Bombay, India. The composition of materials used for ine condenser pumps at the Rajasinan and the Madras Atomic Power Plants are also given. Pump castings and impellers are discussed in detail. Problems in the manufacture of some of the pumps have been briefly reviewed. (INIS)
