Technical Support for Operation and Maintenance of NPPs

Our support for nuclear power plant operators includes a comprehensive set of services from diagnostics and risk-oriented in-service inspection programmes performed directly at power plants and the qualification of inspection methods and security analyses, to umbrella projects increasing the performance and lifetime of nuclear units. We also profile in the transfer of international know-how, especially in the field of nondestructive testing.

Programmes for in-service inspections of safety-critical components for existing NPPs and new VVER-type nuclear sources represent a systematic conceptual solution to design, make changes, consider savings options, and compare NPP operational control programmes to quantifiable objective criteria computed using PSA.

An integrated approach to risk-oriented operational controls and our participation in the exchange of methodologies on a global scale maintains our services at European leadership. To the operators of NPPs, we offer legitimate economic savings and increased return on investment in energy equipment from a safety perspective.
