China plans to develop a safer molten salt nuclear power plant than before

It has been reported that a Chinese research team is planning to develop a molten salt reactor (MSR), a next-generation nuclear reactor that uses liquid thorium as fuel instead of solid fuel rods such as uranium or plutonium. If the development is successful, it will be possible to operate a safer and cleaner nuclear reactor than before, even in deserts where there is little water.

The thorium molten salt reactor TMSR planned by the Chinese government is a reactor with a structure that uses both fuel and coolant in which thorium and fissile materials uranium or plutonium are mixed in fluoride salt. It is said that liquid collapsing cannot occur, and if it leaks, it is safe because it quickly cools and hardens. In addition, since the operating pressure with a high boiling point is low, there is little concern about steam explosion due to temperature rise, unlike cooling using water.

The molten salt reactor concept has been studied in many countries around the world, but no one has been able to realize it due to corrosion of metal pipes by highly corrosive molten salt. The Chinese government has long supported research on molten salt reactors, and the new reactors will use alloys that can withstand corrosion and high temperatures that have been developed through repeated research.

In the sparsely populated area of the Chinese government and the western plains or deserts, the Chinese government aims to build the first nuclear reactor by 2030. In addition, since only a small amount of plutonium is produced from thorium, it is difficult to divert nuclear weapons, so the Chinese government can consider building other countries according to the Belt and Road Initiative.

An official from the Shanghai Institute of Applied Physics, who designed the molten salt reactor, said such small-scale reactors could play an important role in the transition to efficient and economical clean energy, and that molten salt reactors are expected to be widely deployed in the next few years.

Through the monthly AHC PC and HowPC magazine era, he has watched 'technology age' in online IT media such as ZDNet, electronic newspaper Internet manager, editor of Consumer Journal Ivers, TechHolic publisher, and editor of Venture Square. I am curious about this market that is still full of vitality.
