WP2: Decommissioning, the Historic Legacy and Site Termination

Aim To provide new techniques and new technologies ion support of legacy waste management, decommissioning and the monitoring of site end points.

Objectives

To develop innovative approaches to characterisation, retrieval, dewatering, volume reduction and treatment of heterogeneous particulate wastes;

• To investigate the transfer of relevant engineering knowledge from, for example, aerospace and medical technologies into nuclear decommissioning;
• To develop methods for treatment of low level aqueous waste streams, particularly those containing anionic contaminants;
• To develop rapid, selective and sensitive methods for the quantitative measurement of key radionuclides in decommissioning wastes;
• To develop a treatment process for halide -containing orphan wastes compatible with a wasteform suitable for storage and disposal;
• To develop a predictive understanding of preferential contaminant transport via engineered drainage systems;
• To develop approaches for the long term passive monitoring of contamination.
