Fission
A nuclear reaction in which a neutron strikes a relatively large atomic nucleus, which then splits into two or more parts, releasing additional neutrons and energy in forming of heat
1st Energy Transformation - Nuclear Power
Nuclear energy is transformed to heat energy.
Fuel rod
A cylindric tube that encloses nuclear fuel within a nuclear reactor.
Control rod
A cylinder device interred between fuel rods in a nuclear reactor to absorb excess neutrons and slow/stop the fission reactions.
Radioactive waste
Nuclear fuel that can no longer produce enough heat to be useful in a power plant but continues to emit radioactivity.
Curie
A unit measure for radiation
Nuclear fusion
A reaction that occurs when lighter nuclei are foced together to produce heavier nuclei.
2nd Energy Transformation - Nuclear Power
Heat energy is converted to mechanical energy.
3rd Energy Transformation - Nuclear Power
Mechanical energy is converted to electric energy.
Uranium-235
Most commonly used radioactive isotope used for energy production
Radioactive decay
The spontaneous transformation of an unstable atomic nucleus into a lighter one, in which radiation is released in the form of alpha particles, beta particles, gamma rays, and other particles.
half-life
The time taken for the radioactivity of a specified isotope to fall to half its original value.
