Thee Evolution of Reactor Monitoring: From Manual to Intelligent

Traditional CANDU monitoring relies on periodyc manual inspections, rule- based alarm systems, and operator experience. Hundreds of sensors measure colorant temperature, pressure, neutron flux, vibration, and chemistry. While effective, this approvach can miss subtlie degradation parains or slow line evolving faults. AI changes the paradigm by ingesting multidimensional data streas in real time, learning normal operational behavor, and flaginoring alones aloneg before conventionaliers trigger.
