what are the problems of nuclear energy?
46961
Nuclear energy produces radioactive waste A major environmental concern related to nuclear power is the creation of radioactive wastes such as uranium mill tailings, spent (used) reactor fuel, and other radioactive wastes. These materials can remain radioactive and dangerous to human health for thousands of years.

Nuclear power provides over 10% of the world's electricity, and 18% of electricity in OECD countries. Almost all reports on future energy supply from major organisations suggest an increasing role for nuclear power as an environmentally benign way of producing reliable electricity on a large scale.

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.

Answer. The use and cost of energy affects each of us every day of our lives. Many issues arise from the use of energy: greenhouse gas emissions, acid rain, climate change, dependency on depleting supplies of fossil fuels — especially from politically unstable regions of the world.

Generating electricity using nuclear reactors carries high risk but offers large rewards. In operation, a very small amount of nuclear fuel will consistently generate a very large amount of electricity and generate very little polluting material. ... Public perception of nuclear power is negative.

Advantages of Nuclear Energy It generates more than 800 billion kilowatt hours of electricity each year and produces more than 55% of the nation's emissions-free electricity. This avoids more than 470 million metric tons of carbon each year, which is the equivalent of removing 100 million cars off of the road.

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.

The March 2011 nuclear accident at the Fukushima Daiichi nuclear power station affected both short- and long-term energy-security in Japan, resulting in crisis-driven, ad hoc energy policy and, because of the decision to shutter all nuclear reactors, increased the country's demand for fossil fuels, primarily natural ...

Symptoms may include skin burns, nausea, vomiting, diarrhea, hair loss, general weakness and possibly death. In addition to personal health concerns, there are also environmental health concerns associated with nuclear power generation. Nuclear power plants use water from local lakes and rivers for cooling.
