WG 9

System performance and robustness toward external stress

The Working Group WG9 produces and maintains standards and reports on all aspects related to system performance (e.g. validation, verification and calibration of instrumentation systems at the system or channel level including: electronic aspects, processing aspects, safety aspects related to critical safety functions and performance monitoring functions) as well as to system robustness toward external stress. Those stresses can be related to environmental conditions, including seismic and EMI/RFI, but also to malevolent acts. Thus WG9 produces and maintains standards and reports on qualification and on cybersecurity aspects relevant for instrumentation, control and electrical power systems used in nuclear facilities. In particular it covers the coordination of safety and security requirements for instrumentation, control and electrical power systems for nuclear facilities.
