Corus Process Engineering (CPE), part of Corus Northern Engineering Services (CNES) has successfully completed the manufacture and assembly of two, six-metre diameter steel lifting girdles that will be used to remove (lift and tail) the 400-tonne heat exchangers from the reactors at Calder Hall nuclear power plant in Cumbria.
Each reactor has four vertically mounted heat exchangers. These are located externally to the reactor building and were clad for insulation and weather protection. The heat exchangers weigh around 400 tonnes and measure 27m in length with a diameter of 5.5m. This will represent the largest ever lift in the UK nuclear industry. CPE delivered the lifting girdles to its customer Nuvia Limited (formerly NUKEM Limited) at the end of February 2008. Nuvia is one of several contractors chosen by Sellafield Limited to decommission the Calder Hall site.
