FNCA 2002 Workshop on Application
of Electron Accelerator
16 - 20 December 2002,
The 2nd Workshop was held from December 16 through December
30, 2002 at the Takasaki Radiation Chemistry Research Establishment
(TRCRE), Japan Atomic Energy Research Institute (JAERI) sponsored
by the Ministry of Education, Culture, Sports, Science, and
Technology (MEXT) and was attended by experts on application
of electron accelerator from each of the participating countries,
i.e., China, Indonesia, Korea, Malaysia, the Philippines,
Thailand and Vietnam, and 40 participants from Japan.
at FNCA 2002 Workshop
on Application of Electron Accelerator
in Takasaki, Japan
The main topic of the 2nd Workshop was the EB radiation system
for the liquid samples including the demonstration test of
EB system for liquid, review of the radiation systems, and
designing and cost analysis of EB irradiation system.
The participants had the opportunity to discuss, exchange
opinions and share their experiences on issues related to
radiation processing and utilization of low energy electron
accelerators in particular for liquid samples.
Each participating country presented proposal for the cooperation
in the application of low energy electron accelerator, and
some countries have changed their plans from the previous
The major areas of interest of FNCA countries for cooperation
were identified for application of low energy electron accelerator
as liquid, thin film and granules. The gas and wastewater
treatments were added to the above major areas.
Several countries that have low energy electron accelerators,
China, Indonesia, Japan, Korea and Malaysia, have offered
their facilities to be used for the project. Iwasaki Electric
Co., Ltd., Nissin-High Voltage Co., Ltd. and EB-Tech Co.,
Ltd. will consider the possibility of offering their facilities
for the project.
The participants visited Tokyo INK Mfg. Co., Ltd. and Iwasaki
Electric Co., Ltd. They also learned about the flue gas treatment
and soft-electron through videotapes prepared by EBARA Corporation
and Nissin-High Voltage Co., Ltd.
Radiation degradation of chitosan in solution using low energy
electron accelerator was demonstrated at the radiation processing
laboratory of TRCRE and the participants visited a laboratory
for volatile organic compounds (VOC) that uses low energy
At the Round Table Discussion on the fourth day of the Workshop,
discussions were carried out to re-formulate the work plan
of the project for three years until FY 2004 as recommended
at the 3rd FNCA Coordinators Meeting in March 2002.
It was agreed that gas treatment, including flue gas and dioxins
etc., and water purification be included in this program.
The venue of next workshop on the application of electron
accelerator for thin film, including hydrogel, membrane and
packaging film etc., will be held in late August or September
2003, at Malaysian Institute of Nuclear Technology Research
(MINT), or in the city of Kuala Lumpur, Malaysia.
