The contract, which is for 3 and a half years, will provide secondary weatherproofing to the building core during the Care and Maintenance phase of decommissioning.

This is the first phase of the Safestore Height Reduction, which has a total value of over £100m. This involves final deplanting of internal equipment and the demolition of the top 1/3 of the existing reinforced concrete buildings, to the Capping Roof Level and subsequently, the construction of a whole new outer envelope, of steelwork and cladding to blend in with the surrounding countryside.

Costain are one of the four partners in a framework on the site, known as TSIF – Trawsfynydd Strategic Integrated Framework who are delivering the task of decommissioning the high risk areas of the former Nuclear Power Station. This is a unique framework in the nuclear industry, due to the extent of integration between the partners. The other framework partners are AMEC Nuclear, Aker Kvaerner and VT Nuclear Services.

Regional director Huw Llywelyn said:
“This project is a further great opportunity for Costain to prove its pedigree in delivering complex schemes in testing environments. It is a testament to the efforts and excellent working relationship developed between the site team and the Client, Magnox North that the project has finally come to fruition.”
