Norway’s Halden reactor takes first step toward decommissioning
The government of Norway has granted the transfer of the Halden research reactor from the Institute for Energy Technology (IFE) to the state agency Norwegian Nuclear Decommissioning (NND). The 25-MWt Halden boiling water reactor operated from 1958 to 2018 and was used in the research of nuclear fuel, reactor internals, plant procedures and monitoring, and human factors.

This article reports the importance of the correct prediction of turbulent heat transfer in liquid metal flows with the use of Reynolds-Averaged Navier-Stokes (RANS) modelling approach. The Prandtl number of liquid metals is of the order of 0.025-0.001, hence making it very challenging for “off-the-shelf” RANS models to correctly predict the heat transfer phenomena. In this regard, some peculiarities of the “off-theshelf” RANS models are highlighted in different flow regimes, i.e. natural, mixed and forced convection. Furthermore, an updated status and perspectives of the available turbulent heat flux modelling closures within the nuclear community are provided with an especial focus on the low-Prandtl fluids.
