The ultimate goal of this work is the investigation of dynamics of the radionuclide activity in CPC of the WWR-M reactor for the development of safe operation criteria of the reactor core composed by new FA with the enrichment of 19.7% for U-235 isotope. The project will be implemented by means the high-resolution gamma-spectrometry methods as well as alpha- and mass-spectrometry methods. The following works will be performed at the second stage of project: it will be formulated the requirements for the measuring tools, which are capable to implement the procedure of input control of new fuel assemblies (FA) of the WWR-M2 type with the enrichment of 19.7% for U-235 isotope before the loading into reactor core; it will be developed the methods and selected the hard-ware and soft-ware for the practical implementation of the new fuel assemblies input control; it will be carried out the enrichment measurements in the FA fuel elements with the declared mass portion of Uranium (19.7 0.25)% and the measurements of the uniform distribution of U-235 along the core of hexahedral fuel element; it will be carried out the measurements of the surface contamination caused by U-235 radionuclides by means of the alpha-spectrometry for the determination of the Uranium isotopic composition.
