Hinkley Point C
Somerset,
United Kingdom
Hinkley Point C is one of the largest infrastructure projects in Europe, involving the construction of two nuclear reactors.
PERI has been a key delivery partner at Hinkley Point C since 2017, contributing to a number of critical construction phases. One of the most technically challenging stages has been the construction of the reactor domes, which demand advanced formwork solutions and precise coordination to manage complex loading conditions.
The reactor domes present intricate geometric and structural challenges, requiring a highly engineered approach. Each dome is constructed as a double-layered structure, comprising an inner and outer shell. For Unit 1, the inner dome was completed in late 2025, with work progressing to the outer dome in early 2026.
The Project
The challenge extended well beyond geometry. The formwork had to operate approximately 45 m above ground level and support significant construction loads without relying on conventional tie systems. Dense reinforcement and post-tensioning ducts within the reactor structure meant traditional through-ties could not be used.
Initial proposals began as 2D engineering drawings before progressing into 3D CAD and digital models to better visualise the interaction between the formwork, platforms, reinforcement, and surrounding structures.
Our PERI UP scaffolding system can provide a range of solutions on these projects, from temporary integrated access to heavy-duty shoring and reinforcement applications.
