Embedment, penetration, hole closure, and related geotechnical tests associated with subseafloor nuclear waste disposal

Abstract

This report examines some of the factors involved with disposal of both high-level and low-level radioactive waste beneath the seafloor. Topics covered include: (1) seafloor sediment properties, which relate to free-fall emphasized methods of disposal; (2) techniques for predicting embedment or penetration from free-fall of low-level and high-level waste; (3) hole closure behind a penetrating cannister; and (4) geotechnical testing required to predict free-fall penetration depths.
