what is the difference between nuclear power plant and nuclear reactor?
436821
Nuclear reactors are machines that contain and control nuclear chain reactions while releasing heat at a controlled rate. A nuclear power plant uses the heat that a nuclear reactor produces to turn water into steam, which then drives turbine generators that generate electricity.

Cooling towers are constructed for plant cooling and to protect aquatic environments. The nuclear reactor is located inside a containment building, not the cooling tower. The cloud at the top of cooling tower is not radioactive.

One main difference between the two is that the fission events in a reactor are monitored and controlled closely. An atom bomb is an uncontrolled fission chain reaction, that releases exorbitant amounts of energy quickly. The design of a nuclear reactor includes control rods.

As such, nuclear has a capacity factor of close to 100 percent because it typically produces as much generation as possible during every hour of the year. Solar power, on the other hand, can only produce electricity when the sun is out.

Nuclear energy now provides about 10% of the world's electricity from about 440 power reactors. Nuclear is the world's second largest source of low-carbon power (29% of the total in 2017). Over 50 countries utilise nuclear energy in about 220 research reactors.

National security. Nuclear power plants are a potential target for terrorist operations. An attack could cause major explosions, putting population centers at risk, as well as ejecting dangerous radioactive material into the atmosphere and surrounding region.

Nuclear and fossil fuel-burning power plants differ mainly in where their energy comes from; a nuclear reactor produces heat from radioactive metals, and a fossil-fuel plant burns coal, oil or natural gas.

Difference Between a Radiological and Nuclear Emergency. Nuclear incidents involve detonation of a nuclear device whereas radiological incidents produce radiation without detonation of a nuclear device.

Nuclear energy is cleaner while generating electricity. Nuclear fission provides energy without releasing greenhouse gases such as carbon dioxide. However, nuclear power plants generate radioactive waste, a critical factor when doing a fossil fuel to nuclear power pollution comparison.

Nuclear power reactors do not produce direct carbon dioxide emissions. Unlike fossil fuel-fired power plants, nuclear reactors do not produce air pollution or carbon dioxide while operating. However, the processes for mining and refining uranium ore and making reactor fuel all require large amounts of energy.

This is to say that in a conventional power plant, 2/5 of the fuel is turned into useful power, while in a nuclear power plant, 1/3 of the fuel is turned into useful energy. This occurs because conventional power plants can generate steam at a higher temperature [4], therefore providing more force to the turbines.

Nuclear power releases less radiation into the environment than any other major energy source. Second, nuclear power plants operate at much higher capacity factors than renewable energy sources or fossil fuels. ... Nuclear is a clear winner on reliability.

Nuclear power plays a major role. The USA has 98 operating nuclear power reactors in 30 states, operated by 30 different power companies. Since 2001 these plants have achieved an average capacity factor of over 90%, generating up to 807 TWh per year and accounting for about 20% of the total electricity generated.

The evidence over six decades shows that nuclear power is a safe means of generating electricity. The risk of accidents in nuclear power plants is low and declining. The consequences of an accident or terrorist attack are minimal compared with other commonly accepted risks.
