CSNI Task Group on Defence in Depth of Electrical Systems and Grid Interaction (DIDELSYS) – Follow Up

The NEA Committee on the Safety of Nuclear Installations (CSNI) established a task group to examine Defence in Depth of Electrical Systems and Grid Interaction (DIDELSYS). The DIDELSYS Project, carried out in 2008-2009, made recommendations (see the final report NEA/CSNI/R(2009)10) to strengthen the robustness and defence in depth capabilities of individual NPP onsite electric systems. This was done by systematically evaluating the full range of voltage/frequency transient hazards and planting specific capabilities to cope with these hazards.

In December 2009, the CSNI agreed on a DIDELSYS follow-up activity aimed to

The task group produced a technical opinion paper and organised a workshop to discuss the progress made since the publication of the DIDELSYS report.
