Abstract

The CEC is studying the feasibility of using deep ocean sedimentary geological formations as a final disposal medium for vitrified high-level waste and fuel elements. At present, two options are being considered for the embedding of such wastes in the sediment column, using either drilling or free fall penetrators. In the latter case, the high-level waste would be contained in specially designed drums which would be placed in torpedo-shaped projectiles. These penetrators would then be launched from a semi-submersible platform or ship and allowed to fall freely through the water column and bury themselves within the sediment column. The article presents an analysis of the existing design of a model penetrator, with emphasis on body drag, terminal velocity, path stability and hydrodynamic loads on the stabilising surfaces. It includes: - a proposal for modified design for minimum drag and fin size; - an analysis of the effects of instrumentation attached for penetration measurement, and - an analysis of the penetrator behaviour in the case of horizontal attitude drop.
