Dismantling of nuclear facilities

Dismantling of nuclear power plants

The focus of our services when dismantling nuclear facilities is on the technical and quality-assurance level in mechanical and civil engineering. We support you in the planning phase and accompany you throughout all phases in the decommissioning and removal of nuclear units - from consulting on essential disassembly technology or approval procedures, all the way to qualified auditing. We examine nuclear facilities and all quality-assurance measures required in the dismantling process on the highest technical level. Using an interdisciplinary approach and considering realistic risk scenarios, tests as well as controlling requirements, we tailor solutions to our customers' needs.

  • Planning, project support and consulting in the decommissioning and dismantling of nuclear power plants (mechanical and civil engineering)
  • Concept planning all the way to the preparation of contract documents
  • Expert assessment with regard to dismantling techniques
