Preparing for Decontamination and Dismantlement (S. Boden, I. Verwaest, SCK•CEN)
Radiological and physical characterization as a prerequisite for decommissioning tasks. Data management. Presentation and discussion of typical organizational and procedural measures to be taken in preparing to decontaminate/dismantle (e.g., elements of work planning, document retrieval and review, practical issues to “watch out for” from experience).

Overview of Decontamination Techniques
Video + Laboratory Decontamination Demonstrations (Part I)
(K. Van den Dungen, J. Dadoumont, L. Noynaert, SCK•CEN)
Provide a description of approaches, results/experience, advantages/limitations for a range of decontamination approaches for process and structural elements of nuclear facilities as applied at Mol (and elsewhere). Decontamination pre and post-dismantlement. Discuss means and accuracy/reliability of confirming decontamination levels achieved.
Provide visual examples of the techniques in practice through a combination of video/photo examples followed by laboratory/workshop demonstrations.
