THE EVALUATION OF FISSION PRODUCTS INVENTORY IN THE FUEL OF NUCLEAR POWER REACTORS

  • Jan Matuła

Abstract

The production of fission products in a nuclear power reactor core has been discussed in the present paper. The methods of calculating the changes in the concentration rate of the fission products nuclei in the feul during the nuclear reactor operation has been presented. It has been shown that in the steady state the concentration ratio of the given isotope to the initial concentration of U-235 nuclei i s directly proportional to the thermalneutron flux for the most nuclei in the fission products. The simple method of calculating the saturation concentration of the fission products in the fuel of the WWER-440 nuclear reactor has been presented. The activity of 1-131 in the nuclear reactor core of WWER—440 type in the steady state has been given.
