For the Entire Nuclear Life Cycle
From enrichment to reprocessing, from power generation to waste management, our nuclear seal solutions play a role in every step of the nuclear cycle. Our critical components are found in new and existing nuclear power plants, spent fuel casks, fission reactors, enrichment plants and national laboratories. They include nuclear reactor pressure vessel (RPV) closure heads, reactor coolant pump (RCP), quick disconnect systems (QDS), metal seals and gaskets, and much more.
Driving Innovation
Technetics Group is hard at work developing the next generation of sealing components for the nuclear industry. At maestral, the Technetics Group R&D Innovation lab located in the South of France, we’re actively developing new solutions for nuclear generation IV and fusion projects, as well as hydrogen fuel cell and electrolysis projects. We’re working to help solve the most demanding technical challenges to enhance performance and longevity.
