Lithium-7 gained interest for use in nuclear reactor coolants. Tritium is a radioisotope of concern in nuclear reactor waste streams. It is made by bombarding uranium-238 with neutrons in a nuclear reactor. It is an important isotope from the viewpoint of nuclear reactor physics. Samples are exposed to neutrons in a nuclear reactor. InHour is a unit of reactivity of a nuclear reactor. Po can be manufactured by bombarding Bi with neutrons in a nuclear reactor. These delayed neutrons are important to nuclear reactor control. This explains the advantage of using neutron moderator in fission nuclear reactor. It can be created by irradiating Nickel-62 with neutrons in a nuclear reactor. A nuclear submarine is a submarine powered by a nuclear reactor. A kill switch in a nuclear reactor plant is called SCRAM. The neutron flux is a scalar quantity used in nuclear physics and nuclear reactor physics. Framatome is a French nuclear reactor business. Secondary education was provided by CANDU High School, named after a nuclear reactor.
