Gas cooling system, UK (Deadline: none given)

14 February 2011

The UK Atomic Energy Authority is a non departmental government body carrying out research into the potential of nuclear fusion as a future source of energy. The Authority operates MAST, which forms part of the UK & European Fusion Programme with the aim of magnetically confining and studying the behaviour of a plasma in conditions and dimensions approaching those required in a fusion reactor. MAST upgrade is a programme designed to update the machine and push the limits of operations even closer. The upgrade to the machine is to include a new helium cryogenic plant for which the Authority requires:

the design, manufacture and supply of a liquid nitrogen subcooler, including all necessary cryogenic valves.

vacuum insulated coaxial cryogenic transfer lines capable of transporting liquid helium and liquid nitrogen.

the design, manufacture and supply of liquid nitrogen transfer lines including all necessary cryogenic valves.

The scope of the Contractor's work may also include (assistance with) installation and/or commissioning. This PIN has been published to enable market research to commence to asses the reaction of the market to the proposed requirement and review available technologies. The Authority will conduct a dialogue with the marketplace. This may result in a call for competition based on the content of the requirement achieved through the dialogue.
