Automation of radionuclide analysis in nuclear industry

The development results for the automated precise HPGe spectrometers and systems for radionuclide analyses in nuclear industry and environmental monitoring are presented. Automated HPGe spectrometer for radionuclide monitoring of coolant in primary circuit of NPPs is intended for technological monitoring of the radionuclide specific activity in liquid and gaseous flows in the on-line mode. The automated spectrometer based on flowing HPGe detector with the through channel is intended for control of the uniformity of distribution of uranium and/or plutonium in fresh fuel elements, transferred through the detector, as well as for on-line control of the fluids and gases flows with low activity. Automated monitoring system for radionuclide volumetric activity in outlet channels of NPPs is intended for radionuclide monitoring of water reservoirs in the regions of nuclear weapons testing, near nuclear storage, nuclear power plants and other objects of nuclear energetic. Autonomous HPGe spectrometer for deep water radionuclide monitoring is applicable for registration of gamma radionuclides, distributed in water depth up to 3000 m (radioactive wastes storage, wreck of atomic ships, lost nuclear charges, atomic industry technological waste release etc.).(authors)
