A study into the feasibility of instrumentation for deep ocean bed penetrators
To confirm that free-fall penetrators can be used safely and reliably to dispose of radioactive waste by emplacement to a depth of at least 30 m in the sediment at ocean depths of 5 to 6 km, data are required on penetrator performance eg. trajectory, depth of penetration, and following emplacement on sediment behaviour and properties eg. hole closure, pH, pore pressure. The objective of the study is to examine the engineering feasibility and cost of obtaining the required short and long-term (up to one year) data by use of an instrumented half scale penetrator, coupled with a retrievable data recording system housed in a positively buoyant towed package. The penetrator and the towed releasable package are launched from a ship and allowed to fall to the sea bed, whereupon the penetrator enters the sea bed. The releasable package remains above the level of the sea bed attached by its tow cable.
