Shepley is the sole appointed contractor on the hazard reduction deal within the First Generation Magnox Storage Ponds.
The latest win comes after Shepley secured a place on the existing Multi Discipline Site Wide framework and the Decommissioning and Demolition framework at Sellafield.
Shepley is the largest mechanical and electrical contractor at the site.
Brian May, Chief Executive, said: “These new framework appointments reinforce our already strong Engineering Services forward order position.
“The recently announced Government commitment to infrastructure funding confirms the Board’s confidence that Renew’s position as an Engineering Services Group supporting UK infrastructure will provide sustainable, profitable growth in 2012 and beyond.”
