Analysis of electric power distribution system of a large nuclear power plant

Abstract

There have been a considerable number of nuclear reactor concepts proposed over the thirty years of applied nuclear power. A selected number of these have been developed to the extent that one or more plants have been built. Today, only three of these concepts are considered commercially viable. Two of these concepts are based on the use of uranium enriched in the isotope U-235 with light (or ordinary) water employed for cooling and neutron moderation. Of these two concepts, one is the pressurized water reactor or PWR developed by Westinghouse. The other is the boiling water reactor or BWR developed by General Electric. The third concept is based on the use of natural uranium with heavy-water (water enriched in the deuterium isotope) for cooling and moderation. This reactor concept has been principally developed and applied by Atomic Energy of Canada Limited.
