Abstract (en)

[origin: JP2017096955A] PROBLEM TO BE SOLVED: To provide a method for pressure-releasing and inerting waste containers for radioactive waste, which enables inerting and pressure releasing of the waste containers in a simple, effective, and reliable manner.SOLUTION: In the method for pressure-releasing and inerting waste containers for radioactive waste, an adapter (2) with an adapter inner volume (3) is connected to a container (1), in particular to a container cover (4). Subsequently, the adapter is filled with an inert gas under an overpressure and subsequently a connection is established between a container interior (5) and the adapter inner volume (3) to produce a mixed pressure depending on the pressure difference between the pressure in the container interior (5) and the positive pressure in the adapter inner volume (3). Thereafter, the mixed pressure in the container interior (5) is reduced and then a negative pressure is produced in the container interior (5), and the gas removed from the container interior (5) is replaced by an inert gas.SELECTED DRAWING: Figure 1
