Nuclear power's contribution to global energy production was about 4% in 2023. This is a little more than wind power, which provided 3.5% of global energy in 2023. [167] Nuclear power's share of global electricity production has fallen from 16.5% in 1997, in large part because the economics of nuclear power have become more difficult. [168]
Nuclear power stations typically have high capital costs, but low direct fuel costs, with the costs of fuel extraction, processing, use and spent fuel storage internalized costs. [37] Therefore, comparison with other power generation methods is strongly dependent on assumptions about construction timescales and capital financing for nuclear ...
Whereas more classical thermal conversion has been considered with the use of a radiation/boiler/energy exchanger where the X-ray energy is absorbed by a working fluid at temperatures of several thousand degrees, [25] more recent research done by companies developing nuclear aneutronic fusion reactors, like Lawrenceville Plasma Physics (LPP ...
The multiplication factor, k, is defined as (see nuclear chain reaction): k = number of neutrons in one generation / number of neutrons in preceding generation . If k is greater than 1, the chain reaction is supercritical, and the neutron population will grow exponentially.

Nuclear engineering is the engineering discipline concerned with designing and applying systems that utilize the energy released by nuclear processes. [1] [2] The most prominent application of nuclear engineering is the generation of electricity.
In nuclear power technology, burnup is a measure of how much energy is extracted from a given amount of nuclear fuel. [1] It may be measured as the fraction of fuel atoms that underwent fission in %FIMA (fissions per initial heavy metal atom) [2] or %FIFA (fissions per initial fissile atom) [3] as well as the actual energy released per mass of initial fuel in gigawatt-days/metric ton of heavy ...
In nuclear physics, the Bateman equation is a mathematical model describing abundances and activities in a decay chain as a function of time, based on the decay rates and initial abundances. The model was formulated by Ernest Rutherford in 1905 [ 1 ] and the analytical solution was provided by Harry Bateman in 1910.
