Weathertight! Major milestone hit for SRP

Weathertight milestone - final roof pour on SRP

The final concrete pour on the roof slab of our Sellafield Product and Residue Store Retreatment Plant (SRP) process building has been completed. The latest achievement, for one of the site’s largest and most complex infrastructure projects, means the main building is now fully weathertight.

John Leslie, SRP project director, said: “I’m delighted we’ve reached another pivotal moment in the delivery of SRP, and I want to congratulate the team on their latest achievement.

“This is an extremely complex major project to deliver, and through our PPP delivery model we have collaborated with our supply chain partners Kier, Severfield and Mammoet to achieve another significant step forward.

“Delivering projects of this scale and keeping them on track, while keeping everyone safe, is no mean feat and is thanks to the collaboration and professionalism demonstrated everyday by hundreds of people across our supply chain all striving for excellence.”

Facts and figures

To complete this latest milestone, over 2,700 cubic metres of concrete from Sellafield’s new on-site batching plant was poured, pumped up to a height of 30 metres, over a 12-week period to complete the roof slab. Now the process building is weathertight, the facility’s internal and mechanical fit-out will progress, pushing the project closer to its active commissioning and operations in support of the government’s plutonium disposition strategy announced earlier this year.

Louis Twentyman, a graduate of PPP’s internship scheme and now a site engineering apprentice on the project, said: “It’s amazing to be part of a project the scale of SRP, and one with such an important role in the site’s decommissioning.

“Not everyone gets to work on projects of this stature and where there’s something interesting and exciting happening every day. It’s amazing seeing it progress and to be part of it all – I can’t wait to say I helped to build that.”

Confidence

The project is one of only a handful of the country’s major infrastructure projects to hold a ‘green’ delivery confidence rating from the Infrastructure and Projects Authority (IPA), the government’s centre of expertise for infrastructure and major projects.

Once commissioned, SRP will safely receive special nuclear material packages from existing storage locations across the Sellafield site before retreating them into new 100-year packages for safe storage. The SRP facility will enable all special nuclear material to remain safe and secure in its store into the next century and beyond and, therefore, plays a key role in delivering Sellafield’s purpose to create a clean and safe environment for future generations.

Congratulations to everyone involved.

SRP’s roof slab concrete pour gets underway

The first of seven concrete pours on the roof slab of SRP's process building got underway

The first of seven concrete pours on the roof slab of SRP’s process building got underway last week as it progresses towards being fully weathertight, a project wide objective the team is expected to achieve in the coming months.

Around 350 cubic metres of concrete was poured at a rate of 35 cubic metres per hour, pumped up to a height of 30 metres after being delivered using five concrete wagons, in rotation, from our on-site batching plant.

The placing, compacting, and screeding of the concrete was led by a team of 11 people with support from engineers, marshals and technicians.

Construction Manager Gerry Coan said:  “The start of the roof slab concrete pour would not have been possible without the efforts of a whole team of people, which includes our steel-fixers, joiners, marshals, plant and crane operatives, and all the engineering, safety and quality support teams. Well done to all involved.

“If all goes to plan, and weather permitting, the final roof pour will happen at the end of April.”
