Nuclear Power

Nuclear Power

There are many different reactor designs, utilizing different fuels and coolants and incorporating different control schemes. Some of these designs have been engineered to meet a specific need. Reactors for and large naval ships, for example, commonly use as a fuel. This fuel choice increases the reactor's power density and extends the usable life of the nuclear fuel load, but is more expensive and a greater risk to nuclear proliferation than some of the other nuclear fuels.

 This can be controlled by using nd to change the portion of neutrons that will go on to cause more fissions. Nuclear reactors generally have automatic and manual systems to shut the fission reaction down if unsafe conditions are detected

 A cooling system removes heat from the reactor core and transports it to another area of the plant, where the thermal energy can be harnessed to produce electricity or to do other useful work.

 Typically the hot coolant will be used as a heat source for a and the pressurized steam from that boiler will power one or more driven Just as many conventional generate electricity by harnessing the released from burning nuclear power plants convert the energy released from the nucleus of an atom, typically via

A number of new designs for nuclear power generation, collectively known as the are the subject of active research and may be used for practical power generation in the future. Many of these new designs specifically attempt to make fission reactors cleaner, safer and/or less of a risk to the proliferation of nuclear weapons. plants (such as are available to be builtand other designs that are believed to be nearly fool-proof are being pursued., which may be viable in the future, diminish or eliminate many of the risks associated with nuclear fission.^.
One of the first organizations to develop nuclear power was the, for the purpose of propelling an. It has an unblemished record in nuclear safety, perhaps because of the stringent demands of Admiral, who was the driving force behind nuclear marine propulsion as well as the Shippingport Reactor was chief scientist at the U.S. Navy nuclear propulsion division, and was involved with the latter). The U.S. Navy has operated more nuclear reactors than any other entity, including the^] with no publicly known major incidents. The first nuclear-powered submarine,
