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.

Our Services

  • Implementation of operational controls at NPP Dukovany and NPP Temelín sites (VT, PT, MT, UT, PAUT, RT)
  • Operational diagnostics of electric and pneumatic actuators
  • Qualification of new inspection methods and procedures (eg RTG inspections on flooded pipelines)
  • Design and production of test bodies with spark-machining and real defects for qualifying tests
  • Transfer of know-how and current knowledge from the field of non-destructive controls from the world (Russia, USA)
  • Supply of spare parts with special quality requirement according to bill 132/2008 Coll. and bill 309/2005 Coll.
  • Improving the performance of energy sources
