nuclear fission reactor


  • Nuclear Fission and Nuclear Fusion - Purdue University

    The reaction that is most likely to fuel the first fusion reactor is the thermonuclear d-t, or deuterium-tritium, reaction. This reaction fuses two isotopes of hydrogen, deuterium (2 H) and tritium (3 H), to form helium and a neutron.

  • Nuclear fission - Fission chain reactions and their control

    Nuclear fission - Fission chain reactions and their control: The emission of several neutrons in the fission process leads to the possibility of a chain reaction if at least one of the fission neutrons induces fission in another fissile nucleus, which in turn fissions and emits neutrons to continue the chain.

    The Kilopower project, a joint venture between NASA and the Department of Energy, is set to be the first nuclear fission reactor to reach space since the SNAP 10A project in the 1960s. A prototype is in testing, which makes it closer to launch than any of the other projects that popped up in the intervening decades.

  • Nuclear Fission - Fission Reaction

    Nuclear fission is a nuclear reaction in which the nucleus of an atom splits into smaller parts (lighter nuclei). Neutron-induced Fission Reaction

  • BBC - GCSE Bitesize: Nuclear fission

    Nuclear power reactors use a reaction called nuclear fission. Two isotopes in common use as nuclear fuels are uranium-235 and plutonium-239. Two isotopes in common use as nuclear fuels are uranium-235 and plutonium-239.

  • Nuclear reactor - TvWiki, the free encyclopedia

    A reactor that is not moderated is called a fast' reactor because fast neutrons are used to stimulate fission for the chain reaction, whereas a reactor that requires neutron moderation is called a slow reactor or thermal reactor.

  • How Nuclear Fission Power Plants Work - nuclearinfo.net

    A nuclear fission power plant uses the heat generated by a nuclear fission process to drive a steam turbine which generates usable electricity. The underlying physical process is the same for all power plant designs, what differs is the way in which the nuclear reaction is controlled. This is an engineering problem which must take into account ...

  • NASA Just Tested A New Nuclear Fission Reactor, And …

    NASA says it has completed testing on a new nuclear fission power system for deep space missions – and the results went extremely well. The system is called Kilopower, and it involves using the heat generated by uranium to produce power. It’s a $20 million project that’s been billed as a way ...

  • Nuclear Fission Basics - dummies

    The debate over nuclear power plants has been going on for some time, with nuclear physicists and lawmakers alike throwing around terms like nuclear fission, critical mass, and chain reaction.

  • Nuclear fission - Wikipedia

    In nuclear physics and nuclear chemistry, nuclear fission is either a nuclear reaction or a radioactive decay process in which the nucleus of an …
