Development of "Seismic-Resistant Personnel Surface Contamination Monitor"
FAPIG No. 182 pp.3 to 8 (2011)

Radiation facilities such as nuclear power plant are equipped with body surface contamination monitors on a border between controlled area and uncontrolled area to prevent radioactive materialsﾕ expansion to uncontrolled area and check and monitor the radioactive surface contamination of personnel from controlled area to uncontrolled area.
Fuji Electric Systems has manufactured and delivered Body surface contamination monitors and developed ﾒSeismic-resistant personnel surface contamination monitorﾓ to confirm further safety based on the earthquake in the nuclear power plant near the seismic center of Chuetsu Offshore Earthquake in Niigata Prefecture. This "Seismic-resistant personnel surface contamination monitor" has quake resistance for about 15m/s2 (= about 1500 gal = about 1.53G) equivalent to the maximum acceleration of quake of level 7 and was confirmed that the performance and function are not changed before and after the vibration and that body surface contamination measurement can be continued by performing the vibration test equivalent to quake of level 7 with actual equipment.
Characteristics and specifications of ﾒSeismic-resistant personnel surface contamination monitorﾓ, and the evaluation items and results of development are described below.

KEYWORDS：seismic-resistant, body surface contamination monitor

Development of Equipment (2) of MOX Pellet Finishing and Inspection for FBR Fuel
FAPIG No. 182 pp.9 to 14 (2011)

Plan of plutonium use in nuclear reactors to make good use of uranium resource is making progress in Japan for FBR and LWR. Among these reactors, for FBR MOX fuel has been produced in JAEA MOX fuel plant from 1988. And the start of MOX fuel production in JNFL plant for LWR was decided and the plant construction started in 2010.
Fuji Electric has designed and manufactured the production equipment of MOX fuel for FBR from 1990s with engineering instruction by JAEA. As a recent result Fuji Electric supplied "Equipment (2) of MOX pellet finishing and Inspection for FBR fuel" to JAEA in February 2010.
In this document we introduce the summary of "Equipment (2) of MOX pellet finishing and Inspection for FBR fuel".

KEYWORDS：FBR (Fast Breeder Reactor), MOX (Mixed Oxide) pellet, dry type center-less grinding, center-less grinding, pellet size inspection, pellet density inspection, pellet surface inspection, grove box

Development of Fabrication Technology for ITER Toroidal Field Coil
FAPIG No. 182 pp.15 to 20 (2011)

The Japan Atomic Energy Agency (JAEA) is responsible for the procurement of 25% of the Toroidal Field (TF) Coil conductors, 9 TF Coils, and 19 TF Coil structures as the Japanese Domestic Agency (JADA) in the ITER project.
20% of TF Coil conductors have been manufactured and trial fabrications of TF Coil and Coil structures are in progress in collaboration with fabricators.
In this paper I would like to introduce the development of fabrication technology for ITER TF Coil and status of their progress.

KEYWORDS：ITER, fusion energy, troidal field coil, superconducting magnet, coil conductor, coil structure

Development of Gasification Power Generation System Using Woody Biomass
FAPIG No. 182 pp.21 to 25 (2011)

Unused woody biomass in Japan is currently available from various sources such as wood chips from sawmills, material left in woodland areas and builder's waste. Of these, wood chips from sawmills and material left in woodland areas are particularly plentiful, but since they are thinly distributed over extensive mountainous regions, these sources are not utilized effectively.
This study is aimed at developing a small-scale (100kW-1MW Class) distributed power generation system that can make effective use of the unused biomass in these mountainous regions more efficiently and economically than before by combining a fluidized bed gasification furnace with a gas turbine.
In this paper, we report the composition and features of the system and summary of the field test result of 150 kW prototype facility.

KEYWORDS：woody biomass, gasification, gas turbine, power generation

JAEA's New Supercomputer System
FAPIG No. 182 pp.26 to 29 (2011)

To accelerate the nuclear energy research and development by use of computational science, a new supercomputer system was deployed at JAEA in March 2010. The system is mainly composed of a large scale Linux cluster system (PRIMERGY BX900: 200TFLOPS) and a lead off system of the RIKEN's K computer (FX1: 12TFLOPS), whose purposes are to deliver a high-performance parallel computing environment and next-generation nuclear application code development environment, respectively.
In this paper, we introduce the features and functions of the system.

KEYWORDS：supercomputer, computational science, nuclear application

Improvement of Incineration Efficiency of Spent Ion Exchange Resins
on the Incinerator at Nuclear Power Plants
-Manufacturing the Solids of the Resins Mixed with Paraffin Wax and Their Incinerating Test Results on Actual Incinerator-
FAPIG No. 182 pp.30 to 35 (2011)

In nuclear power plants, ion exchange resins are used at water purification systems such as condensate demineralizers. After usage, used ion exchange resins are stored at plants as low level radioactive wastes. Ion exchange resins contain water and so, those are flame resistant materials. At present, ion exchange resins are incinerated with other inflammable materials at incinerators. Furthermore, ion exchange resins are fine particle beads and are easy to be scattered in all directions, so operators must pay attentions for treatment.
Then, we have developed the new solidification system of ion exchange resins with paraffin wax. Ion exchange resins are mixed and extruded with paraffin wax and these solids are enabled to incinerate at existing incinerators. In order to demonstrate this new method, we made the large amount of solids and incinerated them at actual incinerator. From these results, we have estimated to be able to incinerate the solids only at actual incinerator.
