Fast reactors Research on “tank type” different from the one developed in Japan is also under progress at 18:26 on September 1
Regarding the special nuclear power plant called fast reactor, which Japan is researching in collaboration with France, the Japan Atomic Energy Agency has called a "tank-type" fast reactor of a type different from the ones that were previously developed in Japan. We also announced that we will continue research.
A fast reactor is a special nuclear power plant that uses plutonium as a fuel, and it is planned to be put into practical use by the nuclear fuel cycle policy being promoted by the government.
The Japan Atomic Energy Agency, a research institute in the developing country, is conducting research in collaboration with France, which is also developing fast reactors, and announced the results on the way on the 1st.
According to that, it was confirmed that a technique called "tank type" developed by France was confirmed to be technically approved even in Japan where there are many earthquakes, as it was confirmed that a method for improving earthquake resistance was confirmed.
The "tank type" has the merit that the construction cost can be suppressed because the main equipment is housed in the container that covers the reactor and the entire structure can be made compact, but it is said to be vulnerable to earthquakes, and Japan is We have been developing another fast reactor called “loop type” with long piping.
The JAEA will proceed with research on "tank type" as well as "loop type".
However, regarding the development of fast reactors, the Monju, which was constructed in Fukui prefecture for the purpose of commercialization, has been decommissioned four years ago due to cost reasons and development in Japan has stagnated.
Japan Atomic Energy Agency will continue to study design issues such as accident countermeasures, but it is said that the specific construction is undecided at this time.
The country is expected to make full-scale use of fast reactors in the latter half of this century.
