Qualification of Materials

Codes and Standards

Research and Development of materials

Irradiation experimental design and execution

Supply chain analysis

Investment technical Diligence

Example Stories:

Nuclear Energy

We provide materials engineering and design services for advanced fission systems, including Gen IV reactors, SMRs, and high-temperature gas-cooled reactors. Our capabilities include radiation-resistant materials development, component qualification, and support for licensing and regulatory compliance in nuclear-grade environments.
