Safe Operation

TÜV NORD Nuclear provides all services required from the safety perspective in the operation stage. The scope of these services is adapted to the processes and issues relevant for this stage of the life cycle and is detailed below.

From the regulatory perspective, the prerequisite for operating a nuclear facility is a respective license – the license to operate – being granted. Such license requires submission and safety assessment of a Safety Case which defines the procedural and operational framework to be followed in the operation stage. The Safety Case for a license to operate has at least two objectives:

  • To demonstrate that the activities carried out in all preceding stages – planning, construction & erection, commissioning – have been concluded as required and
  • To make credible that the planned operation of the facility complies with the applicable safety requirements.
