Verification Tests for Decommissioning Waste Processing System
Metal Recycling Technique/Dross-Filled Waste Packaging Technique
FAPIG No. 167 pp.3〜10 (2004)

The decommissioning construction of the Tokai nuclear power plant has been advanced since December, 2001. Nuclear Power Engineering Cooperation (NUPEC) has developed techniques of concrete and metal recycling for decommissioning waste for the purpose that the volume reduction of radioactive waste is advanced safely and economically. The metal dross classified as relatively height LLW is generated from thermal cutting of nuclear reactor structural materials.
In order to verify the method which the metal dross could be used for as a material of the waste packaging, tests using an actual scale device was carried out as a part for the NUPEC's verification tests. It became clear that the dross-filled waste packaging technique could contribute to the decrease of the waste volume from this waste packaging test result.

KEYWORDS：decommissioning, radioactive waste, recycling, metal dross, volume reduction, waste packaging technique, verification tests

Outlet Port Radiation Monitoring System
FAPIG No. 167 pp.11〜15 (2004)

Nuclear power plants and related facilities adopt radiation control management based on the State, laws, regulation and related standards.
Our Outlet Port Radiation Monitoring System in nuclear power plants enables to continuously count gamma ray rate in BG level, and save it as data that can be utilized for informations of radiation level in cooling water released from a nuclear power plant.
We are now developping the Outlet Port Radiation Monitoring System collaborating with Tokyo Electric Power Co., Ltd, and installing in Unit from No.1 to No.6 of the first Fukushima Nuclear Power Plant sequentially.
The summary of this system is described as below.

KEYWORDS：radiation monitoring, outlet port, nuclear power plant, NaI (Tl) scintilation detector, backgroud radiation, sampling-pipe

Development of Small-Scale Distributed Power Generation System
Utilizing Woody Biomass Gasification Technology
FAPIG No. 167 pp.16〜21 (2004)

Biomass is well known as the versatile energy resource with non-fossil fuel, and it can be utilized by direct burning, and/or be converted into gaseous or liquid fuels in response to use purpose.
Woody biomass especially features large amount in nature, less emission of NOx, SOx in combustion, and since the biomass absorbs and fixes CO2 in the atmosphere at the time of growth, it is clean energy which does not break down CO2 balance.
This paper reports an outline of technology for utilizing woody biomass energy at Northern Europe, and a development of small-scale distributed power generation system utilizing woody biomass gasification technology at Kawasaki Heavy Industries.

KEYWORDS：woody biomass, small-scale power generation system, gasification technology

Development of the New Data Transmission
and Processing Equipment for Radiation Surveillance
FAPIG No. 167 pp.22〜27 (2004)

In the Mito Atomic Energy Office, which belongs to Ministry of Education, Culture, Sports, Science and Technology, as part of an environmental safety measures of the nuclear institutions in Ibaraki area, the regular surveillance of the environmental monitoring data measured in Japan Nuclear Cycle Development Institute (JNC) and Japan Atomic Energy Research Institute (JAERI) which are main facilities in Oarai and Tokai area is performed.
For the purpose of strengthening environmental radiation surveillance in the fiscal year 2003, the data transmission and processing equipment for radiation surveillance is updated, and the new equipment is actually operated from March, 2004.
In this paper, the features and functions of the new data transmission and processing equipment are introduced.
