In 2018, Tokai Reprocessing Plan (TRP) shifted to the decommissioning stage. In order to proceed with steady decommissioning work, TRP effort to enhance project management function. This paper describes the establishment and role of the Decommissioning Project Management Office, effectiveness of applying the project management tool and its utilization concept, and the method of materialize the equipment dismantling plan.

The Low-radioactive Waste Treatment Facility (LWTF), which aims to provide the safe, efficient and economic treatment and disposal of Low-level Liquid Waste (LLW) generated from LWR spent fuel reprocessing, was constructed at the Tokai Reprocessing Plant (TRP), and a cold test is now being carried out. New treatment processes such as a removal process for radio-nuclides and the ROBE (BORSAURE EINENGUNG ANLAGE) solidification process are being implemented in the LWTF. In order to treat the large amount of sodium nitrate contained in the concentrated LLW with higher safety and economy, R&D work on nitrate-ion decomposition technology using a catalytic reduction method and on the solidification process by cementation is being undertaken. The results of this R&D will be adopted in the LWTF in the near future. This report describes an outline of liquid waste treatment in the LWTF and new treatment technologies for LLW to achieve safe, efficient and economic treatment and disposal.

Performance of -ray spectrum analysis softwares is significantly important because it directly affects the results of nuclide identification and radioactivity measurement. The Expert Committee on Next-generation Gamma-ray Spectrometry, Science and Engineering Committee, Japan Radioisotope Association, performed intercomparison of -ray analysis software by analyzing the same reference spectra with several softwares used in Japan, to know and to improve their performance. It was found that the number of peaks detected by the peak search analysis and deduced peak areas were different among each of the softwares. The reasons why such differences occur are investigated in detail.
