Development and assessment of a nearly autonomous management and control system for advanced reactors

This paper develops a Nearly Autonomous Management and Control (NAMAC) system for advanced reactors. The development process of NAMAC is characterized by three layer-layer architecture: knowledge base, the Digital Twin (DT) developmental layer, operational layer. DT described as acquisition from base intended uses in system. A set DTs with different functions developed acceptable performance assembled according to workflow furnish recommendations operators. To demonstrate capability system, case study designed, where baseline implemented operating simulator Experimental Breeder Reactor II during single loss flow accident. When operated training domain, it can provide reasonable that prevent peak fuel centerline temperature exceeding safety criterion.
