This prevents the fission reaction from continuing and acts as the primary shutdown system in case of emergency. c/o Department of Engineering Physics, Bldg. The first is from aqueous corrosion of the inside surface of the main body of the pressure tube. The reason that a steam generator is used is due to the fact that the heavy water coolant is radioactive from being in direct contact with the reactor core. 0000066395 00000 n Even though CANDU-type reactors look promising in future, light water reactors all over the world proved more efficient than heavy water and in fact only 36 out of 529 power reactors in the world are based on heavy water. 2015.12.03 - Released Chapter 19 - Storage and Disposal of Irradiated Fuel. xref 0000004998 00000 n This has contributed to ease of plant maintenance which, in turn, has contributed to operating reliability and lower operating costs.

Reproduction or translation of any part of this work beyond that permitted by The Canadian It is estimated that power plants using the CANDU design generate more than 23,000 megawatts, about 21% of the electricity produced by nuclear energy. ,��U�@�!������L֙. It combines features of the existing CANDU pressurised heavy water reactors (PHWR) with features of light-water cooled pressurized water reactors (PWR). CANDU is a pressurized heavy water reactor (PHWR) that uses heavy water (deuterium oxide – D2O) as a moderator and coolant, and natural uranium as its fuel. The NPD reactor has no adequate containment system at all, the Douglas Point reactor has one of doubtful effectiveness, and the standard CANDU-600 reactor (versions of which are being built in Argentina, New Brunswick, Quebec and South Korea), has no vacuum building to "suck up" the radioactive steam and gases that are produced in quantity during a LOCA. In some types of reactors, most notably CANDU reactors, the control rods are held up by electromagnets. 2.3.1 India: PHWR-220 design. CANDU reactors use heavy water as the moderator and primary coolant, whereas the first 2 designs use ordinary water as heat transfer medium and neutron moderator, so that they are also called light-water reactors (LWRs). I… None were ever built. %%EOF 2014.11.21 - Revised Chapter 5 to insert missing equation 2. CANDU reactors produce electricity through a process known as fission. D.T. About 4% of the reactor thermal power appears in the moderator, due to gamma radiation, the slowing down of fast neutrons, and heat transferred from the fuel channels. Ingersoll, in Handbook of Small Modular Nuclear Reactors, 2015.
