A nuclear-powered aircraft is a concept for an aircraft intended to be powered by nuclear energy. The intention was to produce a jet engine that would heat compressed air with heat from fission, instead of heat from burning fuel. [1]
The air gained from the compressor section is sent to a plenum that directs the air into the nuclear reactor core. An exchange takes place where the reactor is cooled, but it then heats up the same air and sends it to another plenum. The second plenum directs the air through a turbine (powering the compressor), then out the exhaust, providing ...
Nuclear power plants do not burn fossil fuels and so do not directly emit carbon dioxide. The carbon dioxide emitted during mining, enrichment, fabrication and transport of fuel is small when compared with the carbon dioxide emitted by fossil fuels of similar energy yield, however, these plants still produce other environmentally damaging ...
Nuclear reactors power aircraft carriers by the fission of enriched uranium to boil water, causing turbines to turn and generate electricity. This process is largely the same as in land-based nuclear power stations, but with one notable difference. Naval reactors directly use turboshaft power for turning the ship's screws. Over decades of ...
Nuclear power, with a 10.6% share of world electricity production as of 2013, is the second largest low-carbon power source. [19] Nuclear power, in 2010, also provided two thirds of the twenty seven nation European Union's low-carbon energy, [20] with some EU nations sourcing a large fraction of their electricity from nuclear power; for example ...
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-powered rockets are not used to lift off the Earth. Nuclear thermal rockets can provide great performance advantages compared to chemical propulsion systems. Nuclear power sources could also be used to provide the spacecraft with electrical power for operations and scientific instrumentation. [12] Examples:
A 1965 report suggested synthesizing methanol from carbon dioxide in air using nuclear power for a mobile fuel depot. [62] Shipboard production of synthetic fuel using nuclear power was studied in 1977 and 1995. [63] [64] [65] A 1984 report studied the recovery of carbon dioxide from fossil fuel plants. [66]
