Nuclear CNC Machining
The nuclear sector demands complete confidence in every component. Parts must be manufactured to exact specifications, supported by robust quality systems and delivered with the reliability expected in highly regulated, safety-critical environments.
WEC Machining provides nuclear CNC machining, large machining and precision engineering services for customers across the nuclear supply chain. We support projects involving nuclear decommissioning, new nuclear infrastructure, waste handling, shielding systems, lifting equipment, flask components, specialist assemblies and heavy engineered parts.
With extensive in-house machining capacity, experienced engineers and the wider manufacturing strength of WEC Group, we are well placed to support nuclear customers requiring a dependable UK subcontract machining partner.
From one-off specialist components to large machined fabrications and repeat production, our team works closely with customers to deliver accurate, reliable and fully specification-led nuclear components.
New 60,000 sq ft Heavy Machining and Nuclear Fabrication facility
Our investment in a new 60,000 sq. ft. heavy machining and nuclear fabrication facility represents a major step forward in WEC’s capability to support large-scale, safety-critical manufacturing projects.
The facility has been developed to increase capacity for heavy machining, nuclear fabrication and high-integrity engineered components. With capability for large, complex parts and heavy-duty assemblies, it strengthens our position as a trusted UK manufacturing partner for the nuclear sector.

Commitment to Quality & Compliance
Quality is central to every nuclear machining project. WEC Machining works to controlled processes designed to support accuracy, repeatability, documentation and inspection-led manufacture. When components are destined for nuclear environments, precision and quality cannot be compromised. WEC Machining provides the machining capability, quality focus and project discipline required to support complex nuclear manufacturing.
Nuclear Materials and Grades We Machine
Nuclear precision engineered components are often produced from materials selected for corrosion resistance, strength, stability, wear resistance and long-term performance. Typical nuclear sector materials include:
304, 316, 321, 17-4PH and other stainless grades for corrosion-resistant nuclear components, housings, brackets, plates and fittings.
Duplex 2205 and Super Duplex 2507 for high-strength, corrosion-resistant components used in demanding environments.
EN8, EN19T, EN24T, S275, S355 and other structural or engineering steels for heavy-duty parts, machined frames, blocks and mechanical assemblies.
Inconel, Hastelloy, Monel and other nickel-based alloys for specialist nuclear applications requiring high corrosion resistance, heat resistance or long-term material performance.
Aluminium, bronze and other non-ferrous materials for selected nuclear tooling, fixtures, housings and support components.
PEEK, PTFE, acetal and other polymers for specialist components requiring insulation, chemical resistance or low friction.
Recent Projects

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.
