A fast reactor is a nuclear reactor in which the fission2 chain reaction is sustained by fast neutrons4, and it is highly neutron3 economical, as there is a much larger excess of neutrons not required to sustain the chain reaction, which can be used as extra fuel or to transmute5 long-halflife waste to less troublesome isotopes6. Thus fast reactors7 will contribute a great deal to China’s sustainable development.
Many developed countries set up fast reactors many years ago. For example, one commercial fast reactor in Russia has been in operation for 26 years.
