PREDIS WP5 Objectives © CEA © KIPT © NNL/USFD © SOGIN
§ Study of innovative geopolymers and their interactions with RLOW.
§ Development of direct conditioning solutions for RLOW from TRL3 to
TRL6 including validation tests (real waste) and feasibility scale-up tests.
§ Optimization of geopolymers and formulations for RLOW encapsulation,
especially waste loading and matrix performance.
§ Process robustness regarding waste, raw materials and process variability
including study of the stability and durability of the final waste form.
§ Disposability assessment related to Waste Acceptance Criteria and
scientific approaches for deeper physico-chemical understanding.

PREDIS WP5 Relevance
§ Societal issue. Contribution to a sustainable management of radioactive
waste, limiting the burden to future generations.
§ Environmental and nuclear safety issues. Long-time storage of large
volumes of RLOW awaiting treatment raises questions about nuclear safety
and their potential environmental impact (flammability, toxicity, radiolysis…)
§ Technical issues. Development of flexible and versatile innovative
solutions that can cover a large part of RLOW without management route.
§ Industrial and economic issues. Solutions must be acceptable from
technical and economic points of view for all actors including Waste
Management Organisations and RLOW owners.
