THE SELLAFIELD PRODUCT AND RESIDUE STORE RETREATMENT PLANT
The Sellafield Product and Residue Store Retreatment Plant ( SRP ) project is part of a £ 1bn- £ 1.5bn project funded by the NDA ( Nuclear Decommissioning Authority ) to provide safe storage of special nuclear material for at least 100 years . Delivered through the Programme and Project Partners ( PPP ) model , the project involves the construction of a seismically designed reinforced concrete structure which will act as an annexe to an existing facility .
Kier awarded the project to Enigma due to both organisations working together previously on significant projects at Sellafield . The project scope includes the provision of an innovative and cost-effective access solution to facilitate the formwork , reinforcement and concreting by Kier .
Enigma has been trusted to deliver complex projects on-site at Sellafield for over a decade and have taken advantage of their partnership with HAKI . Due to the system scaffolding incorporating efficiency and adaptability benefits , coupled with an unrivalled safe system of work , Enigma have been able to achieve productivity far greater than would be possible with conventional scaffolding . The HAKI scaffold structure has been designed by Enigma ’ s in-house Design & Engineering Team and requires up to 800 tonnes of equipment and will reach a height of 29 metres .
SRP is one of Sellafield ’ s biggest construction projects and is set to be ready for active commissioning in 2027 . It leverages investment from Sellafield Ltd and its delivery partners , creating long-term construction and manufacturing opportunities for the local and national economies .
The storage of degraded SNM packages in several different stores across Sellafield Ltd presents an intolerable risk position from the potential loss of containment from the failure of a single package . The SRP is required to safely and securely treat and re-package that material into new 100-year packages that will be transferred into the Sellafield Product and Residue Store for long-term storage .
SRP was originally initiated under traditional Sellafield Ltd project delivery practices and transferred to PPP in 2019 during the first year of the new contract model . Each of PPP ’ s current major projects play a vital role in ensuring colleagues can safely empty ponds and silos , manage the waste and store it safely for decades to come .
