[en] Irradiation characteristics examination technology development of irradiated nuclear materials and high burn-up fuels will support not only technical bases of high performance nuclaer fuels and structural materials, which are developed by domestic technologies in the future, but also research of new conceptual design research reactor and fuels. Main objective of this project is to maintain chemical hot cell facility and essential instruments for chemical examination and analysis KAERI has and is to support other nuclear R and D groups and nuclear industries with producing examination data for the specimens requested using these facility and instruments. The objective of the project is to collect, treat and store those radioactive wastes safely for the preservation of the environment from being contaminated by the radioactive wastes generated at KAERI. Therefore, radwastes are disposed of in a disposal site as solidified waste forms for its complete isolation from the human environment. The physicochemical properties of waste forms and the radionuclide concentration in waste forms should be evaluated for the radiological and structural safety of a disposal site, radionuclide type and solidification matrix, and it is difficult to carry out tests(for example, compressive strength, leaching rate, etc)with a full-scale waste forms. The waste classification and acceptance criteria is the result of technology development for characterization of waste and solidified waste forms. This treatment is carry out to low-cost and low-absorbed dose
