New CRP: Advancement of thermo-hydraulic models and predictive tools for the design and operation of SCWR prototypes (I31034)
The IAEA is launching a new Coordinated Research Project (CRP) to support Member States in thermohydraulic modeling, tool development and experimental studies applicable to the design of water-cooled super-critical reactors (SCWRs). The CRP is part of the IAEA’s efforts to support the development of advanced water-cooled reactor (WCR) technologies by promoting information exchange and collaborative research and development (R&D) in the design, evaluation and technical analysis of reactors.
Several conceptual models of SCWR have been developed to generate more than 1000 MWe in Canada, China, the European Union, Japan and the Russian Federation. In addition, the development has been broadened to include the design of Small Super-Critical Modular Reactors (SCSMR) with a production capacity of up to 350 MWe, which can also be adopted as prototypes for benchmark SCWR designs.
SCWRs are advanced reactor concepts designed to operate in light water conditions beyond the critical point (i.e. 22.1 MPa and 374 ° C), providing improved efficiency characteristics over high, better fuel utilization, lower cost and improved safety compared to typical light water reactors.
The CRP specifically aims to advance the design tools and models (system and subchannel codes) supported by computer modeling of fluid dynamics applied to the design of SCWR prototypes based on knowledge and understanding. improved phenomena related to thermal hydraulics such as, but not limited to, heat transfer, hydraulic resistance, instabilities and corrosion effects. Achieving this scope will include the development of new predication models and performance benchmarks on specific phenomena.
The main objective of this CRP is to advance the conceptual SCWR designs towards their prototyping and to fill the existing gaps in their thermo-hydraulic design.
