Abstract

This document presents the status of the Seabed Working Group of the Nuclear Energy Agency examination of the concept of disposing of high level radioactive wastes by burial in the deep ocean floor. Included are summaries of the data and information gathered to date. Seabed burial is a multibarrier concept for the disposal of packaged high level wastes or spent fuel within stable, continuously depositional sedimentary geologic formations of the ocean floor. The objective of the Seabed Working Group is to provide a complete assessment of the feasibility of seabed burial. The determination of technical feasibility can be divided into the following three questions each of which represents a major section of this report: 1. Can sediments in selected locations of the ocean floor, which have good barrier properties, be expected to remain stable for the lengths of time necessary to contain the wastes (Sections II)? 2. Is it possible to emplace waste filled canisters in the seabed sediments in such a way that the barrier properties of the containment system are not impaired (Section III)? 3. What are the radiological consequences of seabed burial (Section IV)?
