TheDepartment of Research Reactors and Tandem Accelerator is in charge of theoperation, utilization and technical development of JRR-3(Japan Research Reactor-3),
JRR-4(Japan Research Reactor-4), NSRR(Nuclear Safety Research Reactor) and Tandem
Accelerator.
This annual report describes a summary of activities of services and technicaldevelopments carried out in the period between April 1, 2007 and March 31, 2008. The
activities were categorized into five service/development fields:(1) Operation and maintenance of research reactors and tandem accelerator(2) Utilization of research reactors and tandem accelerator(3) Upgrading of utilization techniques of research reactors and tandem accelerator(4) Safety administration for research reactors and tandem accelerator(5) International cooperation.
Also contained are lists of publications, meetings, granted permissions on lows andregulations concerning atomic energy, commendation, plans and outcomes in service andtechnical developments and so on.
Keywords: Research Reactor, Annual Report, Reactor Operation, JRR-3, JRR-4, NSRR
