COMPUTATIONAL DETERMINATION OF RADIATION CHARACTERISTICS OF ACTIVATED MEDIUM- AND HIGH-LEVEL RADIOACTIVE WASTE PRODUCED DURING OPERATION OF NPPS WITH VVER
Abstract and keywords
Abstract (English):
The article describes the methodology of computational determination of specific activity of radionuclides in the radioactive waste in the form of spent neutron measurement channels (NMCs) TVS-2M of VVER-1000 reactor. The results of research on the dependence of the specific activity of radionuclides on the NMC lifetime, number of fuel elements, gadolinium amount, enrichment and initial burn-up of fuel assemblies are given. The calculations have been carried out by the Monte Carlo method using the MCU-6 computer program. To verify the results of calculations, a method based on measurements of the gamma radiation dose rate from activated radioactive waste is proposed.

Keywords:
