Operation, Maintenance and Decontamination of the JET Torus Access Facilities

Further enhancements to the JET Facilities' Torus will necessitate breaching highly tritiated environments. This may involve on-site work and/or work in a number of support facilities either by remote handling or manual means. This paper gives a brief in-sight concerning these arrangements and the techniques used to control and contain tritium in it's various forms. Details of enclosures, their ventilation, decontamination techniques and operational experiences from three major engineering shutdowns are discussed in detail.
