Partitioning and Transmutation - Technical Feasibility, Proliferation Resistance and safeguardability
Over the past few years, partitioning and transmutation (P&T) scenarios have been studied worldwide in connection with alternative waste management strategies. In the so-called double strata concept the industrial PUREX process is combined with the advanced partitioning of MA for subsequent transmutation in a dedicated irradiation facility. For this scenario the technical feasibility, the proliferation resistance and the safeguarding potential are investigated and discussed. In the first stratum commercially well-established processes with mature safeguards measures have been established. The second stratum is at present in a development stage; partitioning processes are investigated on a laboratory scale or at best in a scale-up phase in the case of aqueous methods. Alternative pyre-techniques are even less advanced; transmutation experiments are carried out as irradiation test of small targets in experimental reactors. Demonstrators of so-called accelerator driven systems (ADSÆs) are only in the conceptual phase. It is evident that in parallel proliferation and safeguards issues are also far less defined and investigated.
