Development of The Alcohol Waste Processing Equipment
FAPIG No. 168 pp.3〜8 (2004)

In the experimental fast Reactor JOYO, gripper of Fuel Handling Machine and Ex-Vessel Transfer Machine that the sodium adhered is being washed with alcohol. This radioactive alcohol waste that was used to the washing is stored to the tank.
If it is able to separate the alcohol and sodium in the alcohol waste it becomes possible to dispose of the alcohol waste. Japan Nuclear Cycle Institute and Fuji Electric Systems CO., LTD. Developed the device that adds carbonic acid gas to the alcohol waste and cause the sodium in the alcohol waste separated as carbonate and remove this carbonate by using the thin film evaporator.

KEYWORDS:radioactive alcohol waste, carbonic acid gas, carbonate, thin film evaporator

Fusion Neutron Skyshine Experiment at FNS
FAPIG No. 168 pp.9〜13 (2004)

Fusion neutron skyshine experiment have been carried out at the FNS (Fusion Neutronics Source) facility of Japan Atomic Energy Research and Institute.
In this experiment, the skyshine port located just above the tritium target from which fusion neutron produced was open and the radiation dose rate of skyshine neutron that went out through the skyshine port was measured as far as about 550m away from the tritium target with a spherical rem-counter. The measured neutron dose rate was compared with the calculation value by Monte Carlo simulation code MCNP-4B and a simple line source model.

KEYWORDS:FNS facility, skyshine, fusion neutron, MCNP-4B code, rem counter

The 12th WIN Global Annual Meeting in Tokyo
FAPIG No. 168 pp.14〜22 (2004)

WIN (Women in Nuclear) is the network of the woman engaged in the business and research on the nuclear power generation and the radiation which were born in Europe in 1993 for the purpose of deepening an understanding to the general public to atomic power. Now, 57 nations and 2000 members or more are working under WIN-Global which is a world organization. This paper describes the report and results of 12th WIN-Global annual meetingモ which was held at first time in Japan. We participated in this meeting as a pant of PA (Public Acceptance) activity in order to realize the public relation on nuclear power through woman's original viewpoint.

Development of a Plant Dynamics Simulation Code for Helium Gas Cooled Reactors
FAPIG No. 168 pp.23〜26 (2004)

A plant dynamics simulation code has been developed for helium gas cooled reactor plants. The code is equipped with point reactor kinetics, multi-dimensional reactor vessel thermal-hydraulics and volume junction gas turbine system dynamics models. This analysis code enables more realistic evaluation of the plant dynamics under the events such as a depressurization accident

KEYWORDS:the Generation IV International Forum (GIF), helium gas cooled reactor, plant dynamics simulation code, point reactor kinetics, multi-dimensional thermal-hydraulics, volume junction model, gas turbine system dynamics

Research Status and Some Results of Numerical System
to Study Regional Environment: SPEEDI-MP
FAPIG No. 168 pp.27〜32 (2004)

Research status and some results of "Numerical system to study regional environment: SPEEDI-MP", which reproduces circulations of materials in the atmospheric, oceanic and terrestrial environments, are introduced. The purposes of this system are the development of various environmental models, the connection of atmospheric, oceanic and terrestrial models and the construction of research bases for numerical environmental studies. In addition to the accurate prediction of environmental behavior of radionuclides, the system has been applied to the non-nuclear fields, e.g., numerical analysis of environmental effects to volcanic gases from Miyake Jima, real-time prediction of the migration of rice planthoppers from Eastern Asia.

KEYWORDS:environment, prediction, numerical system, computer, radionuclide, volcanic gas, planthoppers

Introduction of Fuel Cell System
FAPIG No. 168 pp.33〜37 (2004)

Fuel Cells are attracting the attention not only for its high efficiency but also for its environmentally-friendliness with less emissions of CO2 or NOX.
Especially, polymer electrolyte fuel cell (PEFC) is recently applied to various fields including stationary fuel cell system as residential cogeneration system, automobiles and mobile power sources.
Ebara Corporation and EBARA BALLARD are pursuing commercialization and application development of stationary PEFC system.
In this report, we introduce overview of fuel cell system and Ebara group's latest approach for residential PEFC cogeneration system and PEFC backup power system.

KEYWORDS:fuel cell, polymer electrolyte fuel cell (PEFC), stationary fuel cell system, residential PEFC cogeneration system, PEFC backup power system
