The Joint European Torus (JET) is an experimental fusion tokamak, capable of operating with deuterium-tritium (D-T) plasmas, located at the Culham Centre for Fusion Energy in Oxfordshire. After 40 years of record-breaking fusion research the JET machine will cease to operate in December 2023 after which the tokamak and its associated facilities will be decommissioned or repurposed. The capability to achieve this will require a full spectrum of nuclear decommissioning capabilities including dismantling and size reduction of the JET machine, processing the associated waste streams (including ILW and LLW), consignment of waste material from site and repurposing existing facilities. 


The purpose of the JET Decommissioning and Repurposing (JDR) programme is to deliver the safe decommissioning and repurposing of the JET facilities in an ethical, innovative manner, demonstrating maximum value for money. JDR is organised into a variety of projects, each delivering an agreed part of the overall technical scope required to deliver the programme.  
JET has historically used ISO containers for the transfer of RH equipment and activated components / assemblies between the JET vessel and other facilities. These containers have been modified with specific features to provide additional radiation shielding, ventilation, and have locating features to enable accurate, repeatable positioning on stillages. The containers are capable of being lifted as shown in the picture below and are attached to facilities through a double lidded door docking system that allows transfer of material between areas under controlled and contained conditions. 

This requirement is for the supply of engineering and manufacturing services as specified . The scope of supply is separated into parts A) and B): 

A)    To prepare the requirements, engineering analysis, calculations, and design of en-hancements to ISO containers so they can be used for an increased scope of activi-ties during JET decommissioning and provide 1 off subject to design approval.


B)    To prepare the requirements, engineering analysis, calculations, and design of the boom addition transport stillage and provide 1 off subject to design approval.
