Report on Administrative Work at Radiation Safety Center in fiscal year 2002

Date of publication:

Feb. 2004

Key words:

safety management, magnetic fusion plasma experiment, radiation protection, radiation measurement and monitoring


National Institute for Fusion Science constructed Large Helical Device (LHD) which is the largest magnetic confinement plasma experimental device using super conductive magnet coils sys tem. It took eight years to construct and the first plasma shot had been carried out on March 1998. Since then high temperature plasma and improved plasma confinement experiment have been achieved. This is the report of administrative work at the radiation safety center considering radiation protection for workers at the LHD and related devices, and radiation measurement and monitoring in the site. Major scope is as follows. (1) Radiation measurement and dose monitoring in the radiation controlled area and in the site using particularly developed monitoring system named as Radiation Monitoring System Applicable to Fusion Experiments (RMSAFE). (2) Establishment of education and registration system for radiation workers and accessing control system for the LHD controlled area. As same as the published reports from fiscal year 1999 and 2001, this report is expected to be helpful for the future radiation safety management in the research institute.
