WebNuclear reactors are significant sources of radiation, especially neutron radiation. At power operation, the fission reaction is responsible for the power generated in a nuclear reactor, and the fission reaction rate is proportional to the neutron flux. Fission essentially ceases when a reactor is shut down, but decay energy is still produced. WebThe Nuclear Radiation Center at Washington State University was established in 1961 as an all-university facility to provide an on-campus nuclear reactor and to provide facilities for nuclear-related educational and research programs for the entire campus.
