MSCM has been granted Fit For Nuclear (F4N) status, awarded on 19 October 2026 by NucCol. The certificate is available to download.

F4N measures manufacturers against the standards the civil nuclear supply chain demands — quality management, safety culture and process control — and it is not a paper exercise. It benchmarks a business against the expectations of nuclear customers and sets out what has to be true before a supplier is ready to bid for that work.

What it means for customers

For more than 25 years, MSCM has built hydraulic distribution equipment that spends 25 to 30 years on the seabed, where recovery is expensive and failure is not an option. Every component is traceable to its material certificate, and every delivery is accompanied by a manufacturing record book. That discipline was built for subsea; F4N confirms it transfers.

Our certified scope reflects the same thing. The quality and environmental management systems BSI certifies — ISO 9001:2015 (FS 629596) and ISO 14001:2015 (EMS 682640) — cover the design, development and manufacture of products for the energy industry, not one sector of it.

The capability behind it

Everything happens under one roof in High Wycombe, which is what keeps quality, schedule and traceability under our own control:

  • Precision CNC machining, including 5-axis milling and turning
  • CNC tube bending and precision pipework
  • Manual and automatic coded welding
  • High-pressure testing up to 1,725 bar
  • In-house NDT: PMI, dye penetrant, radiography, CMM verification and ferrite scope
  • Material certification to EN 10204 3.1 / 3.2
  • Manufacturing record books as standard

Working with us on nuclear projects

F4N status means MSCM is ready to quote nuclear work now — from precision components and subcontract machining through to fabricated assemblies, across new build, operations and decommissioning.
