PREDIS – PRE-DISposal management of radioactive waste – Grant Agreement number: 945098, Work Package “Innovation in metallic waste treatment and conditioning”.
Participants: IMT, VTT, NNL, CEA, SCK CEN, CTU, UJV, CNRS, ORANO, DMT, FZJ, NCSRD , SORC, Nucleco, POLIMI, FTMC, RATEN, CSIC, ENRESA, UAM, GSL, KIPT
The objectives of the Work Package “Innovation in metallic waste treatment and conditioning” are to:
Perform a gap analysis to assess the technology readiness, technology gaps, urgency and important of technology developments during the first project year;
Minimize through new and/ or optimized treatment and decontamination processes, and more efficient characterization of the amount of metallic waste to be disposed of in disposal facilities, by allowing more efficient clearance and recycling;
Contribute to the development of a new reference, stable and safe solution for the storage and final disposal of metallic wastes, including reactive metals, such as aluminum and beryllium;
Estimate of the potential scale of the opportunity to optimize the management of European metallic wastes, including quantification of the benefits in economic terms and application of the waste hierarchy.
NCSRD is leader of the Task “Optimization for metallic waste characterization and procedures for waste minimization and recycling”
Task includes:
Assessment of neutron calculations of several reactors to classify the reactors materials to highly activated zones, zone of intermediate and low activation metal constructions as well as non-activated materials for which only surface contamination is relevant. Furthermore, the DTM radionuclides will be determined at each metallic component and their behavior in decontamination can be foreseen as well as their contribution to clearance. (carried out by FTMC, NCSRD, DMT)
Development of a non-destructive technique and sampling procedure for characterization of metallic waste, to decide if decontamination is needed (clearance criteria haven’t been met and can be met after decontamination) as well as to select the most efficient decontamination process, taking into account that some countries do not allow for clearance, but may still benefit from declassification by decontamination. (carried out by NCSRD, FTMC, DMT, ENRESA, NUCLECO)
Development of robust and validated radiochemical procedures, which are lacking, for DTM radionuclides, significant for decontamination and clearance, in metallic waste. (carried out by IMT, VTT, CTU)
