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 ...
Aircraft Reactor Experiment during assembly showing BeO moderator blocks interlaced with circulating fuel tubes. The Aircraft Reactor Experiment (ARE) was an experimental nuclear reactor designed to test the feasibility of fluid-fuel, high-temperature, high-power-density reactors for the propulsion of supersonic aircraft.
Most commercial nuclear power plants release gaseous and liquid radiological effluents into the environment as a byproduct of the Chemical Volume Control System. These effluents are monitored in the US by the EPA and the NRC. Civilians living within 50 miles (80 km) of a nuclear power plant typically receive about 0.1 μSv per year. [25]
Economists estimate that each nuclear plant built could save more than 800,000 life years.
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 ...
The U.S. government is taking a big step toward forcing a defiant Tennessee company to recall 52 million air bag inflators that could explode, hurl shrapnel and injure or kill people. The National ...
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 ...
