Application of beryllium fluoride in molten salt reactor core
Beryllium fluoride is a chemical substance with the molecular formula BeF2 and the molecular weight of 47.01. White powder or crystal, atomic crystal, covalent compound (this differs from aluminum fluoride), melting point 552℃, boiling point 1175℃, relative density (water =1) 1.9860.
Beryllium fluoride is commonly used as a component of molten salt fuel and secondary heat carrier in molten salt reactors.
World’s first thorium nuclear reactor to start trial operation
Scientists are excited about an experimental nuclear reactor powered by thorium, according to Nature News. Although the radioactive element has been tested in reactors, experts say China is the first country to try to commercialize the technology.
The reactor is unusual in that molten salt is circulated inside, rather than water. It has the potential to produce relatively safe and cheap nuclear power while producing far less long-lived radioactive waste than conventional reactors.
The experimental thorium reactor in China will begin trial operations in late September. According to a previous announcement on the government’s official website, the thorium molten salt reactor system project started construction on September 30, 2018, and the main project was basically completed in May 2021. The electromechanical installation project will start construction in May 2018, be completed by the end of August, and commissioning will start in September.
Thorium based molten salt reactor nuclear power system (TMSR) is one of the six potential technologies for advanced fourth generation nuclear power systems. China is the first country to try to commercialize the new reactor.
Thorium is a relatively weak radioactive silver metal that occurs naturally in rock and currently has almost no industrial use. Scientists say it is waste from China’s booming rare-earth mining industry, making it an attractive alternative to imported uranium.
“Thorium is much more abundant than uranium,” says Lyndon Edwards, a nuclear engineer at the Australian Nuclear Science and Technology Organisation in Sydney. So in 50 or 100 years, when uranium stocks start to decline, this track will have huge potential.”
