In nuclear power technology, burnup is a measure of the neutron irradiation of the fuel. It is normally quoted in megawatt days per ton (MWd/MTU), where ton refers to a metric ton of uranium metal or its equivalent
A measure of nuclear reactor fuel consumption expressed either as the percentage of fuel atoms that have undergone fission or as the amount of energy produced per unit weight of fuel
the amount of fuel used up (as in a nuclear reactor) a high-speed motorcycle race on a public road
The reduced reactivity of spent fuel that occurs from the net depletion of fissile [see fissile definition] nuclides [see nuclides definition] and the net increase in fission and activation product neutron [see neutron definition] absorbers (poisons) is considered (Sandia National Laboratories Overview of Burnup Credit Issues SAND91-2841C, 1992 ) Back to Top
Measure of thermal energy released by nuclear fuel relative to its mass, typically Gigawatt days per tonne (GWd/tU)
A measure of energy obtained from fuel in a reactor Typically, expressed as the amount of energy produced per unit weight of fuel irradiated or "burned " Burnup levels are generally measured in megawattdays thermal per metric ton of initial heavy metal (MWDT/MTIHM)
