Article about the molten salt reactor in Gansu in northern China
Could China's Molten Salt Nuclear Reactor Be a Clean, Safe Source of Energy?
The thorium-powered reactors do not require water as a coolant, meaning they can be built in remote deserts alongside wind and solar power plants
The technology is likely to be safer than uranium-fueled reactors and could also allay some of China's energy security concerns...

IMHO
Nuclear industry propaganda has always sounded super good.
In any case, we are already cheering in advance and in reserve, because when the first experiences with the Chinese molten salt reactor become public, i.e. around the year 2040 and provided that important findings are then published at all (greetings from Julian Assange and Edward Snowden and many more.), we will hardly have any reason to celebrate because we have already gotten so hot by then...

Molten salt reactors
(Molten salt reactor, MSR) or molten salt reactors are nuclear reactors in which the nuclear fuel is in the form of molten salt (for example uranium chloride). With this type of reactor, the nuclear fuel is evenly distributed in liquid form in the primary circuit of the reactor, a core meltdown in the traditional sense is therefore excluded - the core is always in the intentionally molten state. Liquid salt reactors can be designed with a moderator and thermal neutrons or without a moderator with fast neutrons, in both cases operation as a breeder reactor is also possible ...
In the opinion of LFTR critics, the noticeable reluctance of the nuclear industry to deal with the LFTR is based on doubts about its feasibility.
Operational and safety problems
Since fission material and fission products are constantly being diverted out of the active core, the effective proportion of delayed neutrons is low, which significantly impairs controllability.
The deposition of fission products, which are sparingly soluble in the molten salt, on the surfaces of the circuit (plate out) reaches a considerable extent and affects z. B. the maintenance options.
In contrast to most other reactor concepts, there is no modern safety assessment (probabilistic safety analysis PRA / PSA) for molten salt reactors. Overall, the accident spectrum of the LFTR differs significantly from that of other reactor types. Even the development of methods for the safety analysis of LFTR is still at a very early stage.
Stage of development
So far, no reactors have been built in the capacity now designed. Likewise, the necessary reprocessing has not yet been tested on a larger scale. The same applies to the use of and breeding with thorium in molten salt reactors. British nuclear experts estimate the overall development effort required to be so high that it will probably take 40 years for an MSR to be ready for series production.
Proliferation Risks
With thorium as fuel, 233 uranium is also produced in the course of the process. 233Uranium has a similarly small critical mass as 239plutonium, but a much smaller spontaneous fission rate than weapons plutonium, so it is considered an optimal nuclear weapon material ...
disposal
The problem of treating and disposing of slightly to moderately irradiated machine and system parts is similar to that of conventional uranium reactors; the amount is also dependent on the structure and lifespan of the plant, etc. An additional difficulty in disposal is that fission product fluorides are not considered suitable for final storage, i.e. must first be processed into a form suitable for final storage.
Critical expert studies on MSR and thorium use
The British state-owned National Nuclear Laboratories (NNL) have issued several assessments of thorium and LFTR on behalf of the British government since 2010. The main points of criticism are the immature character of these technologies, the largely lacking evidence for the alleged advantages and favorable properties, the unwillingness of the nuclear industry to provide the necessary cost-intensive evidence, and doubts about economic advantages. NNL considers many claims of the Thorium / LFTR proponents to be far exaggerated and therefore warns against euphoria ...

Generation IV International Forum (GIF)
Visions and concepts for new nuclear power plants
The "Generation IV" initiative, with which various visions and concepts for novel and improved nuclear power plants are to be developed, was started in 2000 by the US Department of Energy.
With the designation Generation IV, one would like to differentiate future nuclear power plants from the previous ones: reactor prototypes (Generation I), most of the reactors in operation today (Generation II) and further developed reactors such as the French one Evolutionary Power Reactor EPR (Generation III).
From 2030/2040, new reactors and fuels are to be developed with the aim of achieving maximum safety and economic efficiency in nuclear power plants, significantly reduced uranium requirements, less and shorter-lived radioactive waste and making it more difficult to misuse peaceful nuclear power for military purposes.
Argentina, Brazil, China, France, Great Britain, Japan, Canada, Russia, Switzerland, South Africa, South Korea, the USA and the European Atomic Energy Community EURATOM are involved as partners in the GIF ...
