ICONE(原子力工学国際会議)は、米国、日本、欧州の間で開催される原子力化学工学全般に渡る国際会議であり、今回は第8回目として、米国、ボルチモアで開催された。報告者らは、本学会の以下のセッションにおいて、再処理技術に関する最新の報告を行うと共に、パネル討論や乾式再処理技術等の技術報告の聴講を行った。・Track-5:"Non-reactor Safety and Reliability"のセッションにおける「Investigation of Safety Evaluation Method and Application to Tokai Reprocessing Plant (TRP)」(報告者:中村)・Track-9:"Spent Nuclear Fuel and Waste Processing" のセッションにおける「Structural Improvement on the continuous rotary dissolver」(報告者:鷲谷)・Track-2:"Aging and Modeling of Component Aging, Including Corrosion of Metals and Welds.. Passivation, passive films"のセッションにおける「Development of Evaporators Made of Ti-5% Ta Alloy and Zr ? Endurance Test By Mock-Up Unit」(報告者:高田)今回の学会では、米国、日本、フランス、カナダ他から総勢約650人が参加し、約700件の研究発表、7件の基調講演、8件の招待パネル討論が行われ、大変盛況であった。また、今回は2000年ということもあって、20世紀の原子力の評価と次世代の21世紀の原子力はどうあるべきかについて討議がなされた。また、アルゴンヌ国立研究所(ANL-E、ANL-W)を訪問し、乾式プロセスの研究者らと乾式プロセスに関する情報交換を行うとともに施設見学を行った。今回の訪問で、ANL法の乾式プロセスの情報を入手に加え、装置規模、開発環境、等を具体的に体感できたこと、また、直接、技術者と情報交換することで技術資料のみでは得られない現場サイドの技術情報を入手することができたことは非常に有意義であった。

ICONE(International Conference on Nuclear Engineering) is an international conference on nuclear chemical engineering held among the United States, Japan and Europe, and ICONE8 (the 8th time of the conference) was held at Baltimore, USA on April 2 to 6, 2000. The authors of this paper reported the latest information on the reprocessing technology in the following session of the conference and audited the panel discussion and the technical report of the dry reprocessing technology etc. in the conference. (1)Investigation of Safety Evaluation Method and Application to Tokai Reprocessing Plant (TRP) in session of Track-5 "Non-reactor Safety and Reliability" (Nakamura) (2)Structural Improvement on the continuous rotary dissolver in session of Track-9 "Spent Nuclear Fuel and Waste Processing" (Washiya) (3)Development of Evaporators Made of Ti-5% Ta Alloy and Zr - Endurance Test By Mock-Up unit" in session of Track-2 "Aging and Modeling of Component Aging, Including corrosion of Metals and Welds.. passivation, and passive films" (Takata) At the conference, about 650 people participated from the United States, Japan, France, Canada and others, about700 research announcements, 7 keynote lecture and 8 panel discussion were done, flourishing with many participants. Moreover, as the conference was held in the year of 2000, the evaluation of this century and the direction of the next century of nuclear energy were discussed. After the conference, authors visited Argonne National Laboratory (ANL-E, ANL-W) and exchanged information concerning dry process with researchers of ANL-E and ANL-W, visiting ANL facilities. It was very significant to be able to acquire the information on the dry process developed in ANL and realize the device scale and the development environment, etc. and acquire technical information in detail which would not be able to obtain by engineering data, exchanging information with ANL engineers directly. It is suggested to be very valuable that the ...
