ORCADE-DV D&D Project in La Hague Reprocessing Plant, France Scope: • In La Hague Reprocessing Plant, UP2-400 unit was operating between 1967 and 1998, and re-processing gas- graphite, natural uranium and PWR fuel. • Several buildings and workshops (tanks, ponds, large areas...) needed to be investigated and characterized prior to dismantling for radioactive hold-up. • Lack of knowledge about position, identification and radiological characteristics of residual radioactivity. • In 2007, the customer required a complete engineering solution supporting the different missions of the global ORCADE project including: – Definition of dismantling scenarios – Excellent waste categorization – Radioactive discharge optimization – Safety analysis (dose rate, criticality
