Technical Working Group on Nuclear Power Plant Instrumentation and Control


24th Meeting of the Technical Working Group on Nuclear Power Plant Instrumentation and Control, IAEA, 22-24 May 2013

2013-06-10 | The Technical Working Group on Nuclear Power Plant Instrumentation and Control (TWG-NPPIC) held its 24th meeting at the IAEA in late May 2013. Thirty-five representatives from 19 Member States and 2 international organizations participated.

The TWG is comprised of a group of experts from Member States who provide advice to the IAEA concerning all activities related to nuclear power plant instrumentation and control.

“This technical working group was established in 1970, and it has a long history of actively supporting the Agency’s instrumentation and control programmes”, said Mr Alexander Bychkov, IAEA Deputy Director General for Nuclear Energy, in opening the meeting. “The field of nuclear power plant instrumentation and control is becoming increasingly important in both modernizing existing plants and developing new designs”.

Extended operation needs modernization and upgrades, in particular of instrumentation and control (I&C) systems, as I&C equipment normally becomes much faster outdated than mechanical or civil structures.

The TWG members reported on country activities, discussed current issues, commonly encountered difficulties, and shared best practices and strategies in the design and implementation of Nuclear Power Plant I&C systems.

“The meeting also addressed needs of Member States and provided recommendations for IAEA programme planning and implementation in I&C and on human-system interface (HSI) in nuclear power plants” said Mr Janos Eiler, Scientific Secretary of the TWG-NPPIC.

In the discussion sessions, the recommendations from the participating Member States were reviewed, and a final list was compiled to plan the implementation of the IAEA NENP Nuclear I&C Engineering activities for 2014-2015, and the program for 2016-2017.

As a result of the detailed discussions, the recommendations for future IAEA activities included the following technical areas:

  • Accident monitoring systems for nuclear power plants;
  • Application of Field Programmable Gate Arrays in instrumentation and control systems of NPPs;
  • Wireless technologies;
  • Instrumentation and control in advanced small modular reactors (SMRs);
  • Software evaluation and dependability assessment;
  • Aging management of electrical equipment and components;
  • Support for new plants and newcomer countries;
  • Human factors engineering;
  • Engineering and design aspects of computer security in NPP I&C systems.
