  • 238U which is the bulk of natural uranium is also fissionable with fast neutrons. (wikipedia.org)
  • And so using ordinary water as a moderator will easily absorb so many neutrons that too few are left to sustain a chain reaction with the small isolated 235U nuclei in the fuel, thus precluding criticality in natural uranium. (wikipedia.org)

(publicintegrity.org)
  • Officials from the Office of Naval Reactors - a part of the Energy Department - said in a report to Congress in January 2014, that substituting low-enriched for highly-enriched uranium would raise operating costs, cause more radiation exposure for crews and maintenance workers and generate more radioactive waste.

(belfercenter.org)
  • Because of this, a light-water reactor will require that the 235U isotope be concentrated in its uranium fuel, as enriched uranium, generally between 3% and 5% 235U by weight (the by-product from this process enrichment process is known as depleted uranium, and so consisting mainly of 238U, chemically pure).

  • While heavy water is very expensive to isolate from ordinary water (often referred to as light water in contrast to heavy water), its low absorption of neutrons greatly increases the neutron economy of the reactor, avoiding the need for enriched fuel. (wikipedia.org)
  • The key to maintaining a nuclear chain reaction within a nuclear reactor is to use, on average, exactly one of the neutrons released from each nuclear fission event to stimulate another nuclear fission event (in another fissionable nucleus). (wikipedia.org)
  • The trick to achieving criticality using only natural or low enriched uranium, for which there is no "bare" critical mass, is to slow down the emitted neutrons (without absorbing them) to the point where enough of them may cause further nuclear fission in the small amount of 235U which is available. (wikipedia.org)
  • It has been found beneficial to the neutron economy to physically separate the neutron energy moderation process from the uranium fuel itself, as 238U has a high probability of absorbing neutrons with intermediate kinetic energy levels, a reaction known as "resonance" absorption. (wikipedia.org)
  • The newly released neutrons then go on to bombard other U-235 atoms, setting off a chain reaction that continues until the uranium fuel is used up. (cbc.ca)
