Why are we not using molten salt reactors?
Another basic problem with MSRs is that the materials used to manufacture the various reactor components will be exposed to hot salts that are chemically corrosive, while being bombarded by radioactive particles. So far, there is no material that can perform satisfactorily in such an environment.
When were molten salt reactors invented?
The MSRE control room. The Molten Salt Reactor Experiment achieved its first self-sustaining nuclear reaction on June 1, 1965. Three years later, on Oct. 8, 1968, it became the first reactor ever to run on uranium-233.
Does China have a molten salt reactor?
China launched its molten-salt reactor programme in 2011, investing some 3 billion yuan (US$500 million), according to Ritsuo Yoshioka, former president of the International Thorium Molten-Salt Forum in Oiso, Japan, who has worked closely with Chinese researchers.
Are molten salt reactors the future of energy?
Molten salt reactors are nothing new. They’ve been around since the 1960s and date back to the days of the Molten Salt Reactor Experiment at Oak Ridge National Laboratory. Now, almost 60 years later, several companies are starting to develop them as energy systems of the future—including TerraPower, backed by Bill Gates.
What was the purpose of the molten salt experiment?
The early Aircraft Reactor Experiment was primarily motivated by the small size that the technique offered, while the Molten-Salt Reactor Experiment was a prototype for a thorium fuel cycle breeder nuclear power plant. The increased research into Generation IV reactor designs renewed interest in the technology.
What are the design challenges of MSR nuclear reactors?
Relevant design challenges include the corrosivity of hot salts and the changing chemical composition of the salt as it is transmuted by reactor radiation. MSR cost estimations are uncertain but comparable to or cheaper than LWRs.
When was the last time salt was tested in a nuclear test?
The salt was loaded in 1964 and nuclear operation ended in December 1969, and all the objectives of the experiment were achieved during this period. Checkout and prenuclear tests included 1,000 hours of circulation of flush salt and fuel carrier salt. Nuclear testing of the MSRE began in June 1965]
