Chemical dissolution of radioactive wastes generated from radwastes generated from nuclear power plant

A chemical decomposition method to measure the concentration of radionuclides among radwastes from nuclear power plant is examined since it directly cannot be measured by radioactive detector. For this method, a closed-vessel microwave digestion system is installed, ion exchange resin, active charcoal, zeolite for the treatment of liquid radwastes are dissolve respectively with the application of various acid composition, temperature and time of decomposition, and the power of microwave digestion system. And in order to determine the concentration of radionuclide captured by above-mentioned 3 materials, the elements of non-radioactive sample used in the process of treating radwastes are studied with ICP-AES and AAS
