The nuclear fuel cycle employs a full actinide recycle with two major options: One is an intermediate-size (150–600 MWe) sodium-cooled reactor with uranium-plutonium-minor-actinide-zirconium metal alloy fuel, supported by a fuel cycle based on pyrometallurgical reprocessing in facilities integrated with the reactor. The second is a medium to ...
It was designed to retain gases at about atmospheric pressure and reduce diffusion leakage from potentially contaminated gas. [7] The Sodium Reactor Experiment included a complex of buildings, workshops and support systems. The reactor was housed in the main reactor building, which consisted of a high bay area and a hot cell facility. Three ...
Stewart Brand at a 2010 debate, "Does the world need nuclear energy?" [31]At the 1963 ground-breaking for what would become the world's largest nuclear power plant, President John F. Kennedy declared that nuclear power was a "step on the long road to peace," and that by using "science and technology to achieve significant breakthroughs" that we could "conserve the resources" to leave the world ...
The BN-350 fast-neutron reactor at Aktau, Kazakhstan.It operated between 1973 and 1994. A fast-neutron reactor (FNR) or fast-spectrum reactor or simply a fast reactor is a category of nuclear reactor in which the fission chain reaction is sustained by fast neutrons (carrying energies above 1 MeV, on average), as opposed to slow thermal neutrons used in thermal-neutron reactors.
It is a sodium-cooled fast breeder reactor, based on the Experimental Breeder Reactor II (EBR-II) design, scaled up by a factor of ten. [ 3 ] The design utilizes reactor modules, each having a power output of 311 MWe , to enable factory fabrication at low cost.

The advanced reprocessing of spent nuclear fuel is a potential key to achieve a sustainable nuclear fuel cycle and to tackle the heavy burden of nuclear waste management. In particular, the development of such advanced reprocessing systems may save natural resources, reduce waste inventory and enhance the public acceptance of nuclear energy.
For some countries, nuclear power affords energy independence. In the words of the French, "We have no coal, we have no oil, we have no gas, we have no choice." [19] Japan—similarly lacking in indigenous natural resources for power supply—relied on nuclear power for 1/3 of its energy mix prior to the Fukushima nuclear disaster; since March 2011, Japan has sought to offset the loss of ...
