The present report describes the Proceedings of the Symposium on the Joint Research Project between JAERI and Universities - Results of the 4th Phase Joint Research Project and the Future Plan -, held at the University of Tokyo on February 18, 2003. The joint research project composed of the backend chemistry project and the advanced radiation application project was to be concluded in the end of March 2003. Hence the symposium was held in order to review the results obtained in the 4th phase project and to exchange ideas on the effective measures for the future joint collaboration in view of the past activities.

Radiation energy transfer to extraction solvent in minor actinide separation process were simulated by using a Particle and Heavy Ion Transport code System (PHITS). PHITS enabled to calculate the absorbed dose to extraction solvent in situations of intricately shaped apparatus or oil-water mixed state because the code were based on Monte-Carlo algorithm. It was found that the absorbed dose value from 
-ray depended on the size of the apparatus, while that from alpha-ray was depended on the droplet size in oil-water mixed state. It was demonstrated the degradation yields of the extractant could be evaluated by reference to the experimentally obtained G-values.

Radiation energy transfer to the extraction solvent in minor actinide separation process was simulated by using a Particle and Heavy Ion Transport code System (PHITS). PHITS enabled to calculate the absorbed dose to extraction solvent in situations of intricately shaped apparatus or oil-water mixed state because the code was based on the Monte-Carlo algorithm. Our results suggest that low LET radiation will be the dominant influence on absorbed dose. It was demonstrated the degradation yields of the extractants and the generation yields of the degradation products could be evaluated by reference to the experimentally obtained G-values.
