ABSTRACT
This chapter provides an interdisciplinary understanding of nuclear power generation and proposal of solutions. Nucleons basically consist of protons and neutrons, but only normal hydrogen atoms, only one proton. The type of the nucleus is determined by the number of protons and neutrons, that is, the mass number. Disintegration of radioactive isotopes follows the radioactivity law of nuclides, causing radioactive decay to nuclides of different atomic number and mass number due to alpha decay, or to nuclear species of the same mass number with different atomic number due to beta decay. Since atom is also only a group of protons and neutrons connected by nuclear force, as in molecules, atoms are not as easy as molecules, and composition may change. At the beginning of the 21st century, the mainstream technology of nuclear power generation in the world was light water reactors.
