WebAbout 20 fast neutron reactors (FNR) have already been operating, some since the 1950s, and some supplying electricity commercially. Over 400 reactor-years of operating experience has been accumulated. Fast … 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 or greater, on average), as opposed to slow thermal neutrons used in thermal-neutron … See more Fast reactors operate by the fission of uranium and other heavy atoms, similar to thermal reactors. However, there are crucial differences, arising from the fact that by far most commercial nuclear reactors use a See more All nuclear reactors produce heat which must be removed from the reactor core. Water, the most common coolant in thermal reactors, is generally not feasible for a fast reactor, because it … See more Like thermal reactors, fast-neutron reactors are controlled by keeping the criticality of the reactor reliant on delayed neutrons, with gross control from neutron-absorbing control … See more Fast reactors are widely seen as an essential development because of several advantages over moderated designs. The most studied and built Fast reactor type is the See more Fast-neutron reactors can potentially reduce the radiotoxicity of nuclear waste. Each commercial scale reactor would have an annual waste output of a little more than a ton of fission products, plus trace amounts of transuranics if the most highly radioactive … See more In practice, sustaining a fission chain reaction with fast neutrons means using relatively enriched uranium or plutonium. The reason for this is that fissile reactions are favored at … See more As the perception of the reserves of uranium ore in the 1960s was rather low, and the rate that nuclear power was expected to take over See more

WebFast neutron reactor (FNR): A reactor with no moderator and hence utilising fast neutrons. It normally burns plutonium while producing fissile isotopes in fertile material such as depleted uranium (or thorium). Fertile (of an isotope):Capable of becoming fissile, by capturing neutrons, possibly followed by radioactive decay; e.g. U-238, Pu-240.

WebApr 14, 2024 · If the available neutrons are preferentially used for breeding more fissionable U-233 fuel what is left is a mountain of extremely dangerous spent fuel containing Pa-231 mixed with U-232. Possibly Pa-231 and U-232 could be fissioned in a fast neutron reactor (FNR), but that technology is somewhere in the future.
