Report on Administrative Work at Radiation Safety Center in fiscal year 2001

Date of publication:

Mar. 2003

Key words:

radiation protection, radiation measurement and monitoring, safety of magnetic plasma confinement devices


National Institute for Fusion Science constructed Large Helical Device (LHD) which is the largest magnetic confinement plasma experimental device using super conductive magnet coils. It took eight years to construct and the first plasma shot had been carried out on March 1998. In the experiments high plasma temperature and improved plasma confinement 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 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 access control system for the LHD controlled area. I hope that as like the published reports of fiscal year 1999 and 2000, the present report will be helpful for management of future radiation protection in the research institute.
