Workshop PREDIS - WP4

Friday 24 Nov 2023, 09:00 → 18:00 Europe/Paris

100/-1-A900 - Auditorium Joliot Curie (IJCLab)

About the PREDIS project:

The PREDIS (pre-disposal management of radioactive waste) project targets the development and implementation of activities for pre-disposal treatment of radioactive waste streams other than nuclear fuel and high-level radioactive waste.

The WP4 of PREDIS is dedicated to innovations in metallic treatment and conditioning. The workshop (organized the 24^th of November at IJCLab) will present the activities realized in the frame of this work package and especially in the three technical tasks:

Task 4.4: Development and optimization of decontamination processes

Task 4.5: Optimization of metallic waste characterization and procedures for waste minimization and recycling

Task 4.6: Encapsulation of reactive metals in magnesium phosphate cement-based matrices
