Packaging for ocean disposal of low-level radioactive waste material

摘要

A packaging system for storage of containers of low-level radioactive waste consisting of a concrete shell structure that houses the containers and a dry filler material that surrounds them. Void volume in the filler material is saturated with water, and during free-fall descent to the seafloor, a pressure compensation means equalizes pressures inside and outside the packaging structure and forces the filler material into intimate contact about the drums; on the seafloor, the filler material hardens to produce a highly secure barrier to any leaking of radioactive waste.
