CFD simulations of separate effects in an HTGR lower plenum under air ingress condition

Popis výsledku v původním jazyce

The local heat transfer in an HTGR lower plenum is investigated at the Czech Technical University (CTU) in Prague with collaboration with the U.S. Nuclear Regulatory Commission (NRC). NRC has initiated efforts to build a technical infrastructure necessary to support licensing activities for HTGR's. These efforts include the development and evaluation of computational fluid dynamics (CFD) tools to analyze the system during various conditions. In this case air ingress condition is investigated. The localheat transfer under air ingress condition is strongly affected by the physical phenomena such as molecular diffusion and natural circulation. These separate effects are not yet well understood. Therefore, in the first phase of research it is necessary toperform separate-effects simulations. The CFD solver is exercised and the results are compared with experimental data. The separate-effect benchmarking of the CFD code includes simulations of two separate phases of the JAERI experiments:
