fast neutron - Swedish translation – Linguee

In contrast to most normal nuclear reactors, however, a fast reactor uses a coolant that is not an efficient moderator, such as liquid sodium, so its neutrons remain high-energy. fast reactor[¦fast rē′ak·tər] (nucleonics) A nuclear reactor in which most of the fissions are produced by fast neutrons, with little or no moderator to slow down the Chain reaction in a nuclear reactor at a critical state. Slow neutrons strike nuclei of uranium-235, causing the nuclei to fission, or split, and release fast neutrons. The fast neutrons are absorbed or slowed by the nuclei of a graphite moderator, which allows just enough slow neutrons to continue the fission chain reaction at a constant rate. The reactor vessel has to withstand high pressures (up to 21 MPa). Part # 8.

BN-350, constructed by the Soviet Union in Shevchenko (today's Aqtau) on the Caspian Sea, 130 MWe plus 80,000 tons of fresh water per day. Thermal Reactor Fast Reactor; In thermal reactors, the fission chain reaction is sustained by the thermal neutrons that have energy of 0.025eV and velocity of 2.2km/s. In fast reactors, the chain reaction is sustained by fast neutrons that have energy of 1 – 10MeV and velocity of around 50,000km/s.

Advantages and Disadvantages. The fast neutron spectrum allows fast reactors to largely increase the energy yield from natural uranium as compared to thermal reactors. This high utilization of fuel can extend nuclear power programmes for thousands of years and provide significant improvements in nuclear waste management. Fast reactors are a class of advanced nuclear reactors that have some key advantages over traditional reactors in safety, sustainability, and waste. While traditional reactors contain moderators to slow down neutrons after they’re emitted, fast reactors keep their neutrons moving quickly (hence the name). EIS process launched for US. fast neutron reactor. 06 August 2019.

This high utilization of fuel can extend nuclear power programmes for thousands of years and provide significant improvements in nuclear waste management. Fast reactors are a class of advanced nuclear reactors that have some key advantages over traditional reactors in safety, sustainability, and waste. While traditional reactors contain moderators to slow down neutrons after they’re emitted, fast reactors keep their neutrons moving quickly (hence the name). A fast-neutron reactor is a versatile and efficient power plant. Coupled with regular recycling of its fuel to remove “ashes” of fission products, it can utilize effectively 100% of its uranium fuel. A fast-neutron reactor can manoeuvre. Fast neutron reactor systems have the potential to extract 60 times more energy from uranium compared to existing thermal reactors, and they contribute to a significant reduction in the burden of A sodium-cooled fast reactor is a fast neutron reactor cooled by liquid sodium.
