Nuclear energy is the conversion of its quality by the energy released from the nucleus, consistent with Albert Einstein's equation E = mc ^ 2;, where E = energy, m = mass, c = speed of light constant. The release of nuclear energy, there are three forms:
A. nuclear fission energy. The so-called nuclear fission energy through a number of heavy nuclei (such as uranium -235, U -238, plutonium -239, etc.) of the fission energy released.
B. nuclear fusion energy. By two or more than two hydrogen nuclei (such as hydrogen isotopes - deuterium and tritium) combine to form a heavier nucleus, simultaneous mass loss reaction to the tremendous energy released is called nuclear fusion reaction, called nuclear energy released fusion energy.
C. nuclear decay. Nuclear decay much more slowly is a natural form of fission, energy release because of its slow and difficult to use them.
Use of nuclear energy are the main issues:
(1) resource utilization rate.
(2) response of nuclear waste generated from the biosphere into the potential hazards, and its final disposal technology is not yet fully resolved.
(3) reactor safety issues still need to constantly monitor and improve.
(4) non-proliferation requirements of the constraints, that is, nuclear reactors produce plutonium -239 under control.
(5) investment in nuclear power construction costs remain higher than conventional energy generation, the investment risks.
