ABSTRACT
Nuclear power is economically feasible and meets > 20% of the world demand for electricity, generated by some 440 nuclear power reactors in 32 countries. The extraordinary high energy density of nuclear fuel relative to fossil fuels is an advantageous physical characteristic ([1]). Some countries have successfully utilized nuclear power for power generation. A typical example is France where nuclear power plants produce almost 80% or 45 of its total electricity! In Korea, about 36% of the share of electricity generation is from nuclear sources, with 12 operating nuclear power plants (10 PWRs and 2 pressurized heavy water reactors). Japan has 53 operating nuclear power units with an installed capacity of 42 400 MW(e), supplying 34% of total electricity.
