Industry:Energy
An increase in the rate of fission (and heat production) in a reactor (usually by the removal of control rods from the core).
Industry:Energy
Nuclear reactor fuel that has been used to the extent that it can no longer effectively sustain a chain reaction.
Industry:Energy
An isotope that does not undergo radioactive decay.
Industry:Energy
Plutonium, uranium-233, or uranium enriched in the isotopes uranium-233 or uranium-235.
Industry:Energy
An underwater storage and cooling facility for spent (depleted) fuel assemblies that have been removed from a reactor.
Industry:Energy
A decrease in the rate of fission (and heat/energy production) in a reactor (usually by the insertion of control rods into the core).
Industry:Energy
An unstable isotope of an element that decays or disintegrates spontaneously, thereby emitting radiation. Approximately 5,000 natural and artificial radioisotopes have been identified.
Industry:Energy
The instantaneous amount of reactivity by which the reactor is subcritical or would be subcritical from its present condition assuming all full-length rod cluster assemblies (shutdown and control) are fully inserted except for the single rod cluster assembly of highest reactivity worth that is assumed to be fully withdrawn.
Industry:Energy
Types and amounts of radioactive or hazardous material released to the environment following an accident.
