Decommissioning of GPM05 Harwell


The area contained floor to ceiling glove containment enclosures which were surrounded with a modular containment wall. Our responsibilities included sealing all loose contamination, decontamination, down sizing, removal of all services and finally the removal of the entire modular containment. A new reinforced concrete floor was designed and constructed across the entire floor area. The initial works were carried out in full pressurised (FROG) suits and when airborne levels were reduced, airline fed hoods with PVC over suits were adopted. On completion the surface contamination levels were < 0.4 Bq/cm2 α  &  < 4 Bq/cm2 β. Free breathing conditions were achieved with airborne levels reduced to below 0.01 Bq/m3
