![]() For example, about 10 MeV is released in the form of neutrinos (in fact, antineutrinos). But not all the total energy can be recovered in a reactor. The total energy released in fission can be calculated from binding energies of the initial target nucleus to be fissioned and binding energies of fission products. At first, it is important to distinguish between the total energy released and the energy that can be recovered in a reactor. To calculate the power of a reactor, it is necessary to precisely identify the individual components of this energy. The amount of energy depends strongly on the nucleus to be fissioned and also depends strongly on the kinetic energy of an incident neutron. In general, nuclear fission results in the release of enormous quantities of energy. VĮr – the average recoverable energy per fission (MeV / fission) Now, it is possible to determine the rate of energy release (power) due to the fission reaction. But we also know the amount of energy released per one fission reaction to be about 200 MeV/fission. Σ) by the total volume of the core (V) gives us the total number of reactions occurring in the reactor core per unit time. Multiplying the fission reaction rate per unit volume ( RR = Ф. In this case, the macroscopic cross-sections are independent of position. For simplicity, let assume that the fissionable material is uniformly distributed in the reactor. The fission reaction rate within a nuclear reactor is controlled by several factors. ![]() This proportionality is determined by the fission reaction rate per unit volume ( RR = Ф. ![]() There is a direct proportionality between the neutron fluxand the reactor thermal power in nuclear reactors. ![]()
