JAEA has dismantled equipment and instrument in the JAERI's Reprocessing Test Facility (JRTF) since 1996 as a part of its decommissioning. Starting in JFY 2007, in the annex building B which stored liquid waste generated in wet reprocessing tests, the liquid waste storage tank LV-1 installed in the LV-1 room of the first basement was dismantled with the in-situ dismantling method. The dismantling work is described in this report. Data on manpower, radiation control, and waste in the preparation work were collected, and its work efficiency was analyzed.

A large amount of radioactive waste has been generated in the process of research and development in Nuclear Science Research Institute. We store the equivalent of 130,604 drums (200L) of that in our storage facilities (as of March 31, 2021) and have been developing "Radioactive Waste Information Management System" to manage them for disposal. The system started designing in FY2007 and has been in operation since FY2012. After the start of operation, it has been repaired as appropriate. In this report, we summarized the development and improvement of the system.
