The international standardisation organisation IEC, subcommittee 45A, held its working group meeting at HUN-REN SZTAKI

The international standardisation organisation IEC held its working group meeting at HUN-REN SZTAKI. The Swiss-based IEC (International Electrotechnical Commission) is one of the three major international standardisation organisations (ISO, IEC and ITU). It owns more than 10 thousand international standards. The IEC SC45A subcommittee covers instrumentation, control and power systems for nuclear installations, with the WGA9 working group covering the performance and robustness of systems against external factors.

The two-and-a-half day working group meeting between 14-16 May 2024 was attended by 26 international experts from around the world, including the United States, Japan, Korea, China, Germany and France. The meeting was chaired by Edward Quinn, IEC SC45A WGA9 member and former chairman, with the support of Alexander Wigg, secretary of the IEC SC45A subcommittee.

The working group focused on reviewing selected nuclear control standards and initiating the development of new standards and technical reports. The technical areas discussed covered a wide range of topics, including vulnerabilities of system software and the management of end-of-life system software, the use of artificial intelligence to enhance cyber security in nuclear instrumentation, the safe use of "smart" wireless devices in nuclear systems, and uncertainty assessment in calibration testing and sensor measurement.
