Abstract: A ground-disposable module for encapsulating radioactive waste contained within shipping containers is disclosed herein. Generally, the modules comprise a rigid outer container for providing a first radiation and water barrier for the waste, an inner container formed from the shipping container for providing a second radiation and water barrier, and a central layer of grout which forms still another radiation and water barrier and which provides the rigid outer container with a substantially solid interior which reinforces the compressive strength of the module. The rigid outer container may hold a plurality of shipping containers which have been compacted. Such compaction maximizes the number of containers which may be encapsulated into a particular module, and increases the overall compressive strength of the module by increasing the integrity and strength of the shipping containers and wastes grouted therein.

Abstract: A land disposal site for the disposal of nuclear waste is disclosed which generally comprises a trench, a non-rigid, water-shedding cap formed from alluvium and silt which overlies this depression, and a solid array of waste-containing modules disposed in the trench for both encapsulating the waste and for supporting the non-rigid cap over the depression. The floor of the trench preferably includes a capillary barrier formed from a layer of gravel so that ground water will not seep up into the modules buried within the disposal site. The top surfaces of the modules are covered with a sloped layer of alluvium, which in turn is covered with another capillary barrier of gravel. This capillary barrier of gravel carries a sloped layer of silt which sheds running surface water and directs it into a pair of drains disposed on either side of the trench.

Abstract: A nuclear waste packaging facility for receiving both contact and remote handled nuclear waste in portable shipping containers and encapsulating this waste into ground-disposable modules is disclosed herein. The facility generally comprises a separately shielded section for processing remote handled waste including various remotely-controlled winches and conveyors, as well as a second, separately shielded section for processing contact handled waste. A module transportation and loading section is disposed between the remote and contact handled waste sections of the facility, and places empty module containers in a loading position adjacent each of the two, separately shielded sections of the facility. Both the contact and remote handled waste sections include radiation and ultrasonic detectors for determining the radioactive level of the waste, and whether or not any of this waste is in liquid form.
