Electrical engineering for safe processes in the nuclear industry

Electronic systems are the brains of nuclear power plants and electrical energy is what they need to keep these high risk processes under control. TÜV SÜD supports clients in the nuclear sector to gain confidence that electrical and electronic systems have been correctly designed and implemented and are operated safely and reliabily.

Our services cover the application domains:

  • Reliable electrical power supplies
  • Process instrumentation and control (I&C)
  • Process computing and communication

We begin by evaluating the risk associated with a new design or a retrofitting measure for our customers. During assessment of the proposed system structure and implementation, we determine important safety properties and evaluate the robustness against sporadic or even systematic failure. With ever increasing complexity of electrical systems, we assist customers in alleviate critical common-cause failures and develop new intelligent monitoring strategies for system integrity.

We provide the whole range of monitoring services for safety critical systems and components – from pressure transmitters to power diesel engines – through repetitive testing. With digital equipment or embedded systems in traditional actuators, more sophisticated supervision is necessary that is part of our service portfolio.

TÜV SÜD develops implementation concepts for electromagnetic compatibility and IT security implementation and protection against cyber terrorism. In addition, we provide engineering consulting during all project phases supported by sophisticated measurement equipment and our own trust center.
