Abstract
Methods are discussed for treating liquid and particulate radioactive waste materials for transportation and storage. The disclosed methods include the reading of an ohmmeter connected across a pair of separate and mutually insulated liquid level sensing electrical contacts arranged to contact the surface of a mixture of radioactive waste materials and a setting agent when a container is filled to a predetermined level with that mixture and determining from variations in the resistance between the sensing contacts the time when the mixture is solidified. The disclosed methods also include the flowing of a coating material such as the setting agent unmixed with the radioactive material over the surface of the solidified mixture after the resistance between the sensing contacts reaches a maximum and then causing the coating material to harden and produce a surface free of waste water.
