The technical papers presented here cover nuclear material safety topics on the storage and disposal of excess plutonium and highly enriched uranium fissile materials, including vitrification, mixed oxide fuel fabrication, plutonium ceramics, reprocessing, geological disposal, transportation, and the Russian regulatory process. The book, and the meeting from which it is derived, help to provide a sound basis for maintaining and developing a continuing dialogue between Russian, European, and US experts, improving the safety of future nuclear materials operations in all countries involved. The common objective must be the safe and secure storage and disposal of excess fissile nuclear materials.
