A fast-neutron reactor ( FNR) 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 0.5 MeV or greater, on average), as opposed to thermal neutrons used in thermal-neutron reactors.

Fast-neutron reactors. Fast-neutron reactor (FNR) is a nuclear reactor with a neutron spectrum in its core zone containing mainly neutrons with kinetic energies of the order of 5 MeV. For FNR, there is no need for a neutron moderator, but it requires fuel rich in fissile material.

In fast breeder reactors neutron shielding is provided by using boron, light water, oil or graphite. Gamma-ray shielding is accomplished by lead, concrete with added magnetite or barium etc. The core of a fast reactor needs high enrichment (above 10% of fissile material). To reduce the fuel cost effect, it is imperative to employ high ratings.

Progress Milestones for BREST OD 300 fast-neutron reactor translation in English-Danish dictionary. en They will therefore have to be replaced by reactors incorporating new designs: high-temperature reactors, new pressurised water reactors and new fast neutron reactors.

In order to ensure a safe and efficient reactor operation, fast-neutron induced data They are vital for delayed neutron calculations, reactor poisoning and waste

Based on what little public information there is available about the plans for this facility, it would be a fast reactor of at least 300 thermal megawatts (or about 120 MW of electricity if it is also used for power generation). This power level is the minimum necessary to achieve the desired rate of neutron production. Interest in fast‑neutron reactors persists in the OECD countries for a new reason, political difficulties with storing or disposing of spent fuel. “Reprocessing” spent fuel does not eliminate the problem of siting a geological repository but a reprocessing plant does provide an interim destination that has proved a path A 65 MWt fast neutron reactor - the Chinese Experimental Fast Reactor (CEFR) - was designed by 2003 and built near Beijing by Russia's OKBM Afrikantov in collaboration with OKB Gidropress, NIKIET and the Kurchatov Institute. It achieved first criticality in July 2010, can generate 20 MWe and was grid connected in July 2011. In fast breeder reactors neutron shielding is provided by using boron, light water, oil or graphite.

To reduce the fuel cost effect, it is imperative to employ high ratings. The China Experimental Fast Reactor (CEFR) is China's first fast nuclear reactor, and is located outside Beijing at the China Institute of Atomic Energy.It aims to provide China with fast-reactor design, construction, and operational experience, and will be a key facility for testing and researching components and materials to be used in subsequent fast reactors.

This power level is the minimum necessary to achieve the desired rate of neutron production. This would make the reactor about five times larger than the last experimental fast reactor operated in the United States, the EBR-II, which shut down in 1994.

HISTORY OF FAILURE The history of fast neutron reactors throughout the world has been marked by both safety and economic failure. Thermal neutrons are used to maintain a nuclear chain reaction in a nuclear reactor, and as a research tool in neutron scattering experiments and other applications of neutron science (see below).
