Advanced Numerical and Experimental Studies to Turbulent Buoyancy Driven Flow in the Primary Circuit of Pressurized Water Reactors


Advanced Numerical and Experimental Studies to Turbulent Buoyancy Driven Flow in the Primary Circuit of Pressurized Water Reactors

Höhne, T.

Validated and accurate advanced simulation tools, in particular advanced Computational Fluid Dynamics (CFD) simulation methods, are required to further improve the economics and safe operation of future nuclear power plants.
These methods will be beneficiary for Generation III+ and Generation IV reactors.
Buoyancy driven flows are of relevance for boron dilution transients or pressurized thermal shock scenarios.
Therefore, a combined numerical and experimental study of buoyant mixing processes is planned in the project using existing experiments of the HZDR test facility ROCOM.
A systematic determination of the advantages, disadvantages, and accuracy of these advanced CFD simulation methods for application to NRS assessments is planned.
This will contribute to the development of Generation III+ and IV nuclear reactors, and thereby to the utilization of more efficient and more economical nuclear power in the future.
