Nuclear waste packaging facility

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. The outputs of these detectors are connected to a central computer, which generates a signal indicating how much of the contact or non-contact handled waste may be loaded into a particular module container before the surface radiation of the completed module will exceed a certain, preselected limit. Additionally, the computer actuates an alarm circuit when either of the ultrasonic detectors generates a signal indicating that any of the waste is in liquid form. Finally, a common grouting station having an extendable trough may be used to grout modules loaded from either the contact or remote handled waste sections of the facility. The facility is preferably close to a land burial site to minimize the distance the completed modules must be transported before they are permanently buried.
