Nuclear Cluster
Three partners, one operation: certification & accreditation, codes & standards and training for the nuclear sector, under a single commercial agreement.
×


A dedicated space for the nuclear collaboration
The Nuclear Cluster brings together under a single agreement the three capabilities a nuclear project needs at once: ASME certification and accreditation, access to codes and standards, qualified team training.
For companies in the supply chain it is a single point of contact for the entire regulatory path: from quality system qualification to component stamping, with technical updates and people development already in scope.
Fewer suppliers to coordinate, a more direct route into international nuclear supply chains.
Three partners, three mandates
Each partner owns one area of the ASME path. Together they cover the full cycle, from technical documentation to certification to skills.
