Radioactive wastes generated from nuclear research facilities in Japan Atomic Energy Agency are planned to be buried in the near surface disposal field as trench and pit. Therefore, it is required to establish the method to evaluate the radioactivity concentrations of radioactive wastes until the beginning of disposal. In order to contribute to this work, we collected and analyzed the samples stored at the waste storage facility L. In this report, we summarized the radioactivity concentrations of 12 radionuclides (H, C, Co, Sr, Nb, Cs, Eu, Eu, Pu, Pu, Pu, Am) which were obtained from radiochemical analysis of the samples in fiscal year 2020.

To proceed with the decommissioning of Fukushima Daiichi Nuclear Power Station Accident (1F), it is necessary to secure human resources for radionuclide analysis, which is a prerequisite for the safe treatment and disposal of treated water and waste containing radionuclides generated as a result of the decommissioning. The Nuclear Science Research Institute of JAEA, together with the Fukushima Research and Engineering Institute, has started a project to train analytical personnel who will be responsible for decommissioning in the future. In this presentation, we will introduce the training of analytical operators, managers, and engineers for young staff members and our efforts using the summer intern program.
