Criticality for fast reactor from World Nuclear News by Jeremy Gordon



China has achieved criticality at its first fast neutron reactor, a small unit near Beijing, while plans are developing for a full scale fast reactor power plant in the country.

The Chinese Experimental Fast Reactor (CEFR) achieved sustained fission for the first time yesterday, said owner the China Institute of Atomic Energy (CIEA). The reactor will go on to reach a thermal capacity of 60 MW and produce 20 MW in electrical power for the grid. The first sodium-cooled fast reactor in the country, it was built by Russia's OKBM Afrikantov in collaboration with OKB Gidropress, NIKIET and Kurchatov Institute.

Beyond this pilot plant, China onced planned a 600 MWe commercial scale version by 2020 and a 1500 MWe version in 2030 but these ambitious ideas have been overtaken by the import of ready-developed Russian designs. In October last year an agreement was signed by CIAE and China Nuclear Energy Industry Corporation (CNEIC) with AtomStroyExport to start pre-project and design works for a commercial nuclear power plant with two BN-800 reactors with construction to start in August 2011, probably at a coastal site. The project is expected to lead to bilateral cooperation of fuel cycles for fast reactors, which promise to vastly extend the fuel value of uranium as well as reduce radioactive wastes.
