The use of nuclear energy
The use of nuclear power
In nuclear reactors used to generate electricity, and in many nuclear warheads.
Fabrication of nuclear fuels to generate electricity in nuclear power reactors.
A nuclear reactor uses either nuclear fission or nuclear fusion to generate electricity, while bio-reactors use the excretions of many animals to generate electricity.
Absolutely. All commercial and military nuclear reactors, which are used to generate electricity, use fission.
Primarily, nuclear reactors are used to generate heat, which is used to flash water to steam, which is used to spin turbines, which are used to generate electricity. It is also possible to use reactors for research, as well as for weapons development, such as in the generation of weapons grade Plutonium-239.
To produce electricity
Nuclear fissions in nuclear fuels generate heat and electricity.
In nuclear reactors, to produce electricity
Japan has few natural resources. They have to generate their electricity from imported fuels, primarily fossil (petrochemical) fuels. The nuclear reactor is an option to the use of fossil fuels to generate heat to generate electric power, and for Japan, an island nation, it was one that came with acceptable risks.
Scientists are having difficulty converting the heat into electricity.
It is mostly used to generate electricity, that is all large power reactors can do. There are some small reactors designed to enable samples to be irradiated and removed quickly, to provide radioisotopes for medical and industrial use.
