In 2016, the Nuclear Energy Agency (NEA) Committee on Safety of Nuclear Installations (CSNI) established a permanent Working Group on Electrical Power Systems (WGELEC) as a follow up to the activities DIDELSYS (Defence in Depth of Electrical Systems and Grid Interaction) and ROBELSYS (Robustness of Electrical Systems of Nuclear Power Plants in Light of the Fukushima Daiichi Accident). The working group’s objectives are to improve international understanding on the issues that can lead to a degraded power supply challenging the functionality of equipment relying on electrical power systems, and sharing good practice techniques to prevent, detect and mitigate such events.
As part of their initial tasks, the WGELEC selected several activity items including management of direct current power systems (activity 4), and application of new power electronic and digital devices in safety electrical power systems (activity 5). Since any potential benefit may be gained by promoting knowledge in these two areas (activities 4 and 5) and thereby enhancing nuclear safety, the WGELEC decided to hold a technical meeting, which was jointly organised by the NEA and the IAEA. This technical meeting was designed to be a part of the implementation of activities 4 and 5 by widening participation beyond NEA member countries.
