Amid raising the stricter dose control toward personnel working in nuclear power plant, on dose control and radiation monitoring system for Kyusyu Power Electric Co., Inc, Sendai Nuclear Power Plant, Fuji Electric had manufactured and provided an access control system mounting functions to achieve preventing entering with dosemeter for anyone else or without a dosemeter; reducing exposure by making the exposure level from every work stricter; and reducing burden on personnel, under instruction and cooperation of Kyusyu Power Electric.

Fuji Electric has manufactured large special shape (flat umbrella type) coils in full-scale, which can be downsized, for 500kW class superconducting rotating machines by using YBCO high-temperature superconducting wire along with Industrial Superconductivity Technology Research and Association and Kyushu University for the first time in the world. We confirmed that a magnetic field of 3T (tesla) is generated and the coil withstood the electromagnetic stress of 150 MPa generated at that time. Accordingly, we have a prospect that it can be applied to YBCO superconducting motor. Here we introduce the outline of the retrofit type YBCO superconducting motor, which will replace normal conduction motor, and the developed field coils.

The releases of radioactive materials at the Fukushima Daiichi Nuclear
Power Plant, following the Tohoku earthquake and tsunami on 11 March
2011, are cause of environmental radioactive contamination. It is very
important to resolve health problem and reduce influences living circumstances
as soon as practicable.
KEYWORDSFcesium, decontamination, soil, classification
