NUCLEAR STEEL FABRICATORS

Industry-Leading Nuclear Fabrication Capabilities

WEC Fabrication brings decades of specialised experience to the manufacture of complex components for the nuclear sector. From containment and pressure vessels to lifting frames, fluorine cells, and structural steelwork, our capabilities cover the full spectrum of nuclear metal fabrication.

Our collaborative approach ensures each project is delivered to the highest specification, backed by detailed design, LTQR (Lifetime Quality Records), and Non-Destructive Testing (NDT) methods. We also operate a dedicated clean welding room for nuclear stainless steel, ensuring no carbon steel is ever present and maintaining the highest standards of contamination control. We are a trusted partner to major clients across the UK nuclear supply chain, supporting critical infrastructure and waste management operations.

Recent Projects

West Fence

Designed to aid the safe working at heights on a nuclear material handler, we worked with the customer to design and fabricate this protective fence.

Fabricated from quality Grade 3 steel the full build to print project took 6 months, including undergoing an extensive FAT procedure before being dispatched to site.

Duplex Waste Handling Table

Fabricated to enable robot sorting of hazardous nuclear waste, this Duplex Waste Handling Table was fully manufactured at our WEC Group site in Darwen, using a mix of 304, 316 quality grade 2 & Duplex steel.

Working closely with the customer, the build to print fabrication process took 2.5 years to deliver a qualilty finish, with the finished product delivered to the customer ahead of schedule.

LLTP Platform Project

Designed to traverse a hazardous container from rolling stock to the processing facility and made from 100% quality Grade 2 steel, we recently completed this barrier gate for one of our valued customers.

The build to print process took 2 years with full traceability of material used. Including welding, NDT and paint reports.

Case Studies

Demineralised Water Pump Skid

The Demineralised Water Pump Skid was designed and manufactured for a valued customer in the nuclear sector to safely supply demineralised water for the decontamination of robotic equipment, with built-in protection to prevent contaminated water from flowing back into the mains supply. Developed in line with an agreed inspection and test plan, the system underwent rigorous quality controls including certified materials, approved procedures, dimensional checks, non-destructive testing, chemical cleaning, and full factory acceptance testing to ensure fitness for purpose.

Fabricated primarily from 304L and 316L stainless steel, the skid was produced using a combination of in-house capabilities and trusted specialist suppliers for machining, electrical works, testing, and cleaning. From accepted inspection plan to completion, the project took just over a year and forms part of an ongoing programme of BEP packages supporting complex nuclear handling and recovery systems.
