Post Shutdown Decay Heat Removal In Fast Reactors - 9781916706781

In a nuclear reactor, most of the nuclear fission energy appears as heat, which is generally utilized to produce steam for the generation of electricity. The final step is similar to that used in fossil-fueled power plant. Coming to the basics of nuclear energy, the mass of a nucleus is always less than the mass of the constituent nucleons. The difference is known as mass defect. The energy equivalent of the mass defect is called the binding energy of the nucleus. This is the energy required to break apart the nucleus into its constituent nucleons. The theory of relativity explains the relation between the mass defect and the binding energy as E = m ? 931.3 where E is in MeV and m is the mass in atomic mass units. The binding energy per nucleon is relatively low for nuclei of small mass number but increases, with increasing mass number to a broad maximum at about 8 MeV in the mass region of roughly 50 to 75; subsequently the binding energy per nucleon decreases steadily. The nucleus of lower binding energy per nucleon is less stable and is converted into others of higher binding energy, i.e., more stable accompanied by a release of energy. Hence, the energy can be obtained by combination (or fusion) of the light nuclei or by splitting (or fission) of heavy nuclei.
