The energy density of nuclear fuel is several million times higher than that of fossil fuels, so the fuel used in nuclear power plants is small and easy to transport and store. A 1,000-megawatt nuclear power plant requires only 30 tonnes of uranium fuel per year. The used for the airplane can be completed with one time delivery. The Nuclear power generation costs, the proportion of fuel costs is low, the cost of nuclear power generation is less affected by the international economic situation, so the cost of electricity than other power generation methods for stability. But there is some disadvantage of the nuclear power. First Nuclear power plants will produce high to low level radioactive waste, or the use of nuclear fuel, although the volume is small, but because of radiation, it must be handled carefully, and the need to face considerable political distress. (Mattew 5) Second, the Nuclear power plant's thermal efficiency is low, and thus more than the general fossil fuel power plant emissions of waste heat to the environment, so the nuclear power plant thermal pollution is more serious. And if want to build the nuclear power plant, then will have to issue with the political. The government will not let company build the …show more content…
It is very similar to fire power. Only nuclear reactors and steam generators to replace the thermal power of the boiler to nuclear fission can replace fossil fuel chemical removal, other types of power reactors are a loop of coolant through the heart heat, In the steam generator to the heat transfer to the two-loop or three-loop water, and then the formation of steam to promote the turbine generator. The boiling water reactor is a circuit of the coolant through the heart of the heart heat into 70 or so saturated steam, after the separation and drying of hot water directly to promote the turbine generator. Nuclear heat generated by the use of uranium fuel for nuclear separation reaction caused by heat, the water heated to high temperature and high pressure, nuclear reaction released by the heat than the burning of fossil fuels released by the energy much higher (about a million times), compared to the required Fuel volume is much less than fire power plant. Of the uranium 235 is only about 3% to 4% pure, and the rest are uranium that can not produce nuclei 238. For example, the nuclear plant will use 80 tons of nuclear fuel per year, as long as two standard containers can be carried.("nuclear energy"
