NUCLEAR SAFETY CONTROL SYSTEMS

ISO Ingénierie has been assisting the major players in the nuclear sector (EDF, CEA, DCNS, ITER, ILL,…) for more than 20 years throughout the safety life cycle of their nuclear safety control systems, from the initial design phases to the qualification with the Nuclear Safety Authority (ASN), in accordance with the standards of the SC45a subcommittee: IEC 61513, IEC 61226, IEC 62671, IEC 60880, IEC 62138, IEC 60780…

Assistance to designers and operators of INB

  • Classification of nuclear safety functions (category A, B or C) according to IEC 61226
  • Elaboration of the requirement framework to be qualified (normative, environmental, functional and operational)
  • Definition of global architectures (IEC 61513)
  • Requirement specification of the nuclear safety control systems
  • Redaction of the Preliminary Safety Report (PRSR) for the control system part
  • Assistance in the monitoring of the Safety Systems qualification
  • Safety and cybersecurity coordination (IEC 62859)
  • Writing a cybersecurity program (IEC 62645)
  • Assistance for answers to the ASN
  • Assistance in the Operational Condition Maintenance (OCM) Strategy

Assistance to system and component suppliers/manufacturers

  • Definition of the qualification strategy and redaction of the Qualification Plan
  • Redaction of the System Quality Assurance Plan
  • Requirement engineering and requirement monitoring with Reqtify or DOORS
  • Third party reviewer of the safety life cycle
  • Qualification of pre-existing equipment (COTS): PLCs (IEC 62138) – Smart Devices / ANFL (IEC 62671) – FPGA (IEC 62566)
  • Analysis/Definition of Instrumentation & Control architectures (IEC 60709 / IEC 62340)
  • Assistance in the qualification of application software (IEC 62138)
  • Writing a cybersecurity program (IEC 62645)
  • Environmental qualification (IEC 60780 / IEC 60980 / IEC 61000) and K1 / K2 / K3 according to RCC-E
  • Structuring of the system qualification files
  • Impact and non-regression analysis

Our training service in the nuclear sector

ISO Ingénierie has developed a 2-day training course on the theme “IEC 61513 standard and qualification process“. This training has been provided to many actors in the nuclear sector in France. The objective of this training is to provide applicants with the knowledge and methods to establish the requirements for instrumentation and control systems and equipment (I&C systems) used to carry out functions important to safety in nuclear power plants, classified as Category A, B or C.
