Definition of burn-up in English English dictionary
Nuclear fuel is used up much as a tank of gas is used up in a car Burn-up is usually measured by the percent of fuel burned or in the amount of energy created as a result of burn-up in megawatt days per ton of fuel
The amount of energy produced by fission reactions in relation to the amount of fissile material originally available
The amount of energy that has been generated from a unit of nuclear fuel; usually measured in megawatt-days thermal per metric tons of initial heavy metal (MWdth/MTIHM)
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
If something burns up or if fire burns it up, it is completely destroyed by fire or strong heat. The satellite re-entered the atmosphere and burned up Fires have burned up 180,000 acres of timber
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 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
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)
