USING PLASTIC TRACK DETECTORS TO SOLVE RADIATION SAFETY PROBLEMS AT NUCLEAR-REACTOR FACILITIES

Three options of the method to determine microconcentrations of fissil e materials in water solutions are developed. They utilize plastic tra ck detectors to measure concentrations. The options are as follows a ' 'wet'' method, ''thin-layer inorganic sorbents-plastic track detectors '', and a method of selective extraction and coprecipitation. These me thods are used to check up fuel cladding integrity at the research rea ctor IVV-2M and liquid radioactive waste contamination by uranium and plutonium at the Beloyarskaya Nuclear Power Plant (BNPP).
