Rusatom Automated Control Systems (RASU JSC) has tested the In-Core Instrumentation System (ICIS) and System for Integrated Analysis (SIA) for Kudankulam Nuclear Power Plant Unit 3 in India. The subsystems ensure the acquisition, analysis, and transmission of information on the reactor state to the Main Control Room. The equipment will be shipped to the Kudankulam site before the end of 2023. The ICIS is an important part of the Instrumentation and Control System, monitoring nuclear fuel and reactor safety parameters. The Humidity Leak Monitoring System and Acoustic Leak Monitoring System are used to detect potential leaks.
