Destructive and non-destructive tests for radioactive waste packages
Quality control of radioactive waste has to be performed prior to interim storage or final disposal. It can be achieved either by random tests on conditioned radioactive waste packages or by process qualification of the conditioning processes. One of the most important criteria is the activity of the radioactive waste product or packages. To obtain preliminary information on the waste package, gamma-spectrometric measurements are performed as a non-destructive test. Besides the gamma-emitting nuclides, the alpha- and beta-emitting nuclides can be estimated by calculation if the waste was generated in nuclear power plants and the nuclide relations are known. If the non-destructive determination of nuclides is not sufficient or the non-radioactive content of the waste packages has to be identified, sampling from the waste packages has to be performed. This can best be done by core drilling. To obtain greater knowledge about process qualification for super-compaction, instrumentation of the super-compaction process was investigated and tested. The variation of pressure versus time or distance were plotted during supercompaction of about 100 drums with different contents of simulated waste, as was the spring-back effect of the pellets.
