Firm is signed up for engineering, procurement and construction of major evaporator project
Costain has secured a £297m nuclear contract at Sellafield for full engineering, procurement and construction of the Evaporator D project - one of the largest nuclear projects in the UK.
The contract, which also includes inactive commissioning of the evaporator, is an extension of an original purchase order, awarded in September 2006 for front-end engineering design.
Costain has developed the design of the facilities that will be used to expand Sellafield’s ability to process nuclear waste material.
One solution employed by Costain is off-site modularised construction, where modules are shipped in by sea, and transported across the River Ehen to Carlisle rail lines.
The housed evaporator building will comprise 15 in-cell modules, over 22km of pipework bound together by over 10,000 welds, 300 tonnes of specialist steel and 400 major plant items.
The project is scheduled for completion in 2014.
