Overview
This transparency notice is issued to advise the market that the United Kingdom Atomic Energy Authority (UKAEA) intends to award a framework contract to Kinectrics Inc. for the design, manufacture, factory acceptance testing, delivery, installation support and commissioning support of the glovebox assemblies forming part of the Isotope Separation System (ISS) of the H3AT Tritium Loop Facility at Culham Campus, Oxfordshire, together with the associated professional design services. H3AT is constructing a tritium fuel cycle facility providing a closed-loop simulation plant and experimental laboratory.
The ISS is a critical subsystem responsible for isotope separation using cryogenic and glovebox technologies. The gloveboxes provide the contained working environment necessary for tritium handling within the separation process and are a prerequisite to introducing active materials into the facility. The framework will be established under the NEC4 suite, with call-off contracts placed under the NEC4 Engineering and Construction Contract for manufacture and build scope and the NEC4 Professional Services Contract for design and advisory scope, as the design matures.
