FAQ

Q. How are Nuclear Power Plants regulated in Japan?

A. To control the legal and safety framework governing nuclear power plants in Japan, the Nuclear Regulation Authority was founded in 2012. They are in charge of issuing the Construction Permits and conducting safety inspections of all nuclear sites. Security rules, radiation monitoring, and inspections all contribute to the nuclear power plant’s overall safety.

Q. What Nuclear Reactors have been used in Japan?

A. Pressurized water reactors and boiling water reactors, both built by General Electric, have been the two principal types of nuclear reactors utilized in nuclear power facilities in Japan. Additionally, there have been experimental reactors like Spreckels-1 and Edgu-2 or Edgu-3. Only pressurized water reactors are in use right now.

Q. How is waste from Nuclear Power Plants handled in Japan?

A. Japan’s nuclear power reactors create spent fuel waste, which is treated to minimize its bulk before being stored in a secure location. Depending on the quantities, it either goes to a storage facility or a recycling factory. Intermediate-level waste and low-level waste are the two categories used to describe radioactive waste. The latter comprises the majority of all nuclear waste kinds. Japan has set up the Radioactive Waste Management Center of Japan to manage and control the waste.

Q. What is the purpose of the Diet in Japan regarding Nuclear Power Plants?

A. The Diet, which is Japan’s legislative body, is in charge of passing regulations governing nuclear power plants there. The Japanese Diet is assisted in developing nuclear safety rules and regulations by the Nuclear Safety Commission of Japan. To regulate nuclear power plant safety, the commission is in charge of creating safety regulations and other control measures.

Q. How is Nuclear Power generated in Japan?

A. Nuclear fission is used to produce nuclear electricity in Japan. In a nuclear power plant, neutrons are used to split (fission) uranium or plutonium atoms in order to liberate energy. By heating water to the point where it becomes steam, this energy is used to generate thermal energy, which in turn powers turbines. Electricity is then produced by these turbines.
