本勉強会は、福島第一原子力発電所の燃料デブリ取出しとそれに関連した水化学及び材料の課題を分野横断的に検討するため、「燃料-材料-海水の相互反応」をテーマとして、日本原子力学会の核燃料部会、水化学部会、材料部会が合同で開催するものである。本講演では、燃料デブリの基礎性状に関するこれまでの研究成果のうち、特に燃料デブリと海水塩の高温反応生成物と、燃料とB$$_{4}$$C制御棒の溶融固化物中の生成相に関する知見を紹介する。

This joint meeting is held by Division of Nuclear Fuel, Division of Water Chemistry, and Materials Science and Technology Division of Atomic Energy Society of Japan. The key topic is "Interaction among fuel, reactor materials and seawater" in order to discuss the problems within the fuel debris removal operation from the view points of materials and water chemistry. This presentation introduces the recent results of characteristic studies on simulated fuel debris, especially on the high temperature reaction products between simulated corium debris and sea salt deposit, and on the solidified melt among materials of UO$$_{2}$$ fuel and B$$_{4}$$C control blade.
