The heat energy of the fission fragments is harnessed as nuclear power and turned into electricity.

The atoms are the smallest constituents of ordinary matter, which can be divided without the release of electrically charged particles. Pdf introduction to the nuclear power industry researchgate. Nuclear power plants generate electricity in much the same way that other thermal power plants generate electricity. Nuclear power will continue to be a key component of a portfolio of technologies that. Nuclear energy research and development roadmap executive summary to achieve energy security and greenhouse gas ghg emission reduction objectives, the united states must develop and deploy clean, affordable, domestic energy sources as quickly as possible. Nuclear binding energy curve the binding energy curve is obtained by dividing the total nuclear binding energy by the number of nucleons. The fact that there is a peak in the binding energy curve in the region of stability near iron means that either the breakup of heavier nuclei fission or.
