Steel pressure vessel, UK (no deadline specified)

1 November 2010

The UK Atomic Energy Authority has a requirement for a large stainless steel vacuum vessel. The vessel is to be cuboid in topology and approximately 3m long 2 m wide 3,5 m high in size. It must contain an ultra-high vacuum with a very low leak rate. The top surface of the vessel will be a (bolted) removable lid, designed to withstand the internal vacuum as well as support the weight of internal components, the latter up to a total of 8 tonnes. This lid will have a number of feed-throughs to provide water and electrical services. The vacuum vessel will also feature two large penetrations on the two opposite faces 2 m by 3,5 m high. The vessel will be supported on a height-adjustable support frame.

The scope of work for the production of the vacuum vessel could include (but is not limited to): production of the manufacturing drawings, manufacture of all jigs and fixtures, manufacture of system components to final dimensions, qualification of processes, cleaning to UHV standards and inspection and testing.

This notice 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.
