The difference is that nuclear plants do not burn anything. Instead, they use uranium fuel, consisting of solid ceramic pellets, to produce electricity through a process called fission. Nuclear power plants obtain the heat needed to produce steam through a physical process.
How is a nuclear power plant different from this fossil fuel power plant?
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.
How is nuclear energy generation different from fossil fuel energy generation quizlet?
They both use heat to generate steam and drive turbines to produce electricity. They mainly differ in where their heat comes from; a nuclear reactor uses radioactive decay, and a fossil–fuel plant burns coal, oil or natural gas.
What do nuclear power plants and fossil fuel burning power plants have in common quizlet?
Both nuclear and fossil fuel power plants produce electricity the same way. The heat generated in these plants is used to generate steam. This steam drives a turbine, which powers a generator that converts mechanical energy to electrical energy.
How are nuclear power plants different from coal fired power plants quizlet?
Coal–fired power plants use chemical energy, whereas nuclear power plants use nuclear fission as a source of heat to produce steam.
Why nuclear energy is bad?
Nuclear energy has no place in a safe, clean, sustainable future. Nuclear energy is both expensive and dangerous, and just because nuclear pollution is invisible doesn’t mean it’s clean. … New nuclear plants are more expensive and take longer to build than renewable energy sources like wind or solar.
Is nuclear cheaper than solar?
When it comes to the cost of energy from new power plants, onshore wind and solar are now the cheapest sources—costing less than gas, geothermal, coal, or nuclear. … Utility-scale solar arrays are now the least costly option to build and operate.
What drives the turbine in a nuclear power plant?
Nuclear power plants use heat produced during nuclear fission to heat water. … The heat produced during nuclear fission in the reactor core is used to boil water into steam, which turns the blades of a steam turbine. As the turbine blades turn, they drive generators that make electricity.
Which statement explains why nuclear waste materials may pose a problem *?
This waste is highly toxic in nature. Being possessed by radio-active nuclear substance they have long half-lives which allows them to be remain radioactive for extended periods of time. Their ability to be remain radioactive for extended periods of time poses a great problem for the experts.
Which issue is associated with nuclear power is the biggest source of debate?
Nuclear waste disposal is one of the most controversial facets of the nuclear power debate. Presently, waste is mainly stored at individual reactor sites and there are over 430 locations around the world where radioactive material continues to accumulate.
What factors make nuclear power expensive?
What factors make nuclear power expensive? Safety controls, waste storage, and plant maintenance.
Which fossil fuel reserves will last the longest?
Coal and natural gas are expected to last a little longer. If we continue to use these fossil fuels at the current rate without finding additional reserves, it is expected that coal and natural gas will last until 2060.
Which is not true of radioactive half life?
“Radioactive half–life is increased by heating the isotope” is not true. Explanation: The radioactive half–life is the time required for half of any given amount of a substance (or isotope), to undergo radioactive decay.
What is the main difference between a coal fired power plant and a nuclear power plant?
Coal Energy vs Nuclear Energy
Two popular options are coal energy and nuclear energy. The main difference between coal energy and nuclear energy is the type of fuel they use. Nuclear energy uses enriched radioactive elements like uranium to produce heat in a process called nuclear fission.
What is mined to produce the fuel for nuclear power?
Uranium is the main fuel for nuclear reactors, and it can be found in many places around the world. In order to make the fuel, uranium is mined and goes through refining and enrichment before being loaded into a nuclear reactor.
What is the amount of time that it takes for the radiation in a sample of uranium 235 waste to be reduced by half quizlet?
The amount of time it takes for the radiation in a sample of uranium-235 waste to be reduced by half is __________. 700 million years. This is the half-life of uranium-235. What disabled the emergency power generators at the Fukushima Daiichi nuclear plant in Japan and led to the reactor meltdowns?
