The aim of this work is to create software and instrumentation complex and methodological basis for the study of processes of radioactivity in the primary circuit water-water nuclear reactors and establishment of laws in these processes in order to improve the radiation process control basic parameters of the reactor. Used to investigate methods gamma-spectrometry of high resolution, mathematical modeling, calculations by the Monte-Carlo and statistical methods of analysis. According to the requirements of regulations for the evaluation of radiation core of nuclear reactors is required continuous monitoring of activity of reference radionuclides in primary circuit. Developed by the ideology of gamma-spectrometric complex for continuous monitoring of radionuclides in primary circuit water-water reactors by gamma-spectrometry of high resolution, select the optimal modes of some of its units for measuring specific activity of radionuclides of iodine in the range from 10-3 Bq / kg to 10-9 Bq / kg; developed software algorithms for discrete-continuous measurement and analysis of gamma-spectrs primary circuit reactor, developed algorithms for calculating the specific activity of radionuclides of iodine (131-I - 135-I); studied the dynamics of radionuclide activity in primary circuit of 2-nd unit WWR-1000 Khmelnytsky NPP during depressurization membranes fuel rods; offered informative sets of radionuclides for monitoring process parameters water-water nuclear reactors.
