Nuclear Regulatory Commission in order to receive approval of an increase in the reactor's maximum allowable power level.
Reactors on nuclear-powered Navy vessels have valves that would shut off pressurized water from the reactor, but commercial firms did not install such systems.
Nuclear reactors in operation today have made significant improvements in efficiency that have increased electricity production by as much as 25 percent over the past decade.

Nuclear warheads , high level radioactive waste and reactors from discarded submarines are to be destroyed by nuclear detonations on Nova Zemlya.
Although these RBMK nuclear reactors designed in Russia are considered unsafe they are still operating because of the great need in Ukraine for electrical power.
In 1945 nuclear reactors at Hanford, in the United States, produced the first plutonium for nuclear weapons.

Nuclear reactors provide energy that can be used to directly heat a working fluid (typically hydrogen) and provide thrust through an expansion similar to other thermal rockets.
Nuclear reactors fuelled with uranium can be used to produce artificial radioactive substances called "radioisotopes" for use in industry, scientific research and medicine.
Unlike nuclear reactors or nuclear weapons, no fission process is involved in the operation of RTGs, nor is a fission process possible given the type of plutonium used and the design of the RTG.

She is longer than a Nimitz class ship because her nuclear reactors are larger than the smaller, more efficient reactors in a Nimitz class ship.
Nuclear power reactors are recognized in the aftermath of the attacks on the Twin Towers and Pentagon, as terrorist targets.
Propulsion: Two nuclear reactors, permitting the ship to steam more than one million miles before refueling.
