Abstract: Liquid-containing radioactive wastes are bound into thermoplastic material by introducing particles of thermoplastic material at a non-sticking temperature into a kneading machine, heating the thermoplastic material in the absence of radioactive wastes to at least 100.degree. C., adding the liquid-containing wastes to the heated thermoplastic material, mixing and concurrently increasing the temperature of the mixture to a temperature of about 200.degree. C. or more to vaporize liquid in the mixture, maintaining the mixture at a vaporization temperature to dry to the mixture, releasing evolved vapors and discharging the dried mixture from the kneading machine. Difficulties due to clogging of the kneading machine and fluctuations in the consistency of the dried end product are minimized.

Abstract: An apparatus admits gas into the primary coolant of a pressurized water nuclear reactor having a coolant loop for a liquid coolant, in particular water, to which hydrogen is to be added. The coolant loop preferably includes a volume control tank for the coolant as well as at least one high-pressure pump which admits coolant that has been extracted from the coolant loop back into the coolant loop again. An admission point for the hydrogen is located in a suction line on the suction side of the high-pressure pump. A measurement line on the pressure side of the high-pressure pump communicates with the volume control tank or with a dewatering system. A device for measuring the hydrogen content in the coolant is incorporated into the measurement line. The measuring device is connected through a control device to a control valve, with which the delivery of hydrogen to the admission point can be controlled. The gas admission apparatus assures a definite, precisely maintained hydrogen content in the coolant.

Abstract: Mixing devices such as worm machines used for embedding radioactive wastes in hot bitumen are cleaned to remove residual bitumen and salt incrustations in three successive operations: (a) Washing with a solvent for bitumen in a volume amount equal to about the free space of the device. (b) Rinsing with a water-soluble rinsing medium miscible with the solvent in a volume amount the same as (a). (c) Rinsing with demineralized water in a volume amount twice (b). Pumice gravel is used to absorb the solvent and rinsing medium and the resultant pumice embedded in bitumen and sent to ultimate storage.
