We should abandon further use of nuclear power for electric power supply.

Nuclear power plant System Cost Safety There are three reasons why I think so. First, What kind of system does the nuclear power plant run on? Second, How much does it cost to operate the nuclear power plants? Third, Is the nuclear power plant safe?

First, System Thermal Power Nuclear Power Plant First, What kind of system does the nuclear power plant run on? Like a thermal power plant, a nuclear power plant boils water to make steam and turns a turbine connected to a generator with the power of steam to make electricity. The thermal power plant boils water by burning fuel oil, coal, natural gas with a boiler to make steam. However, nuclear power plants boil water by using the heat generated by nuclear fission of uranium in nuclear reactors. Nuclear Power Plant

Second,　　　　 Cost Second, How much does it cost to operate the nuclear power plants The cost of thermal power generation per 1 kWh is 12.3 yen when using coal, 13.7 yen when using natural gas and 30.6 to 43.4 yen when using oil. Also it can be said that thermal power plants are high in fuel costs, and CO2 countermeasure expenses. But nuclear power plant is not cost it. Also, the power generation cost of nuclear power plants seems to be 1 kWh per 10.1 yen, so it seems cheap. However, the social cost when the accident occurred was extremely high, and in Fukushima accident it cost about 20 trillion yen.

Third, Safety Third, Is the nuclear power plant safe? Nuclear power generation is very dangerous to human beings. The nuclear reactions by which electric power is generated produce radioactive substances. These substances are hazardous to health and some of them are known to be carcinogenic. Also, we can never build absolutely safe nuclear power stations that can stand against any natural disaster. Once a nuclear power station is destroyed by whatever natural disaster, the impact is enormous and long lasting, as we know through the experiences of Fukushima.

　　　　　 Conclusion For these three points I think we should abandon further use of nuclear power for electric power supply. Thank you!
