    Abstract

    The liquid metal-cooled reactor is a Generation IV reactor concept aiming to provide safe, economic and sustainable nuclear energy in future. Understanding the thermal-hydraulic phenomena occurring in a liquid metal reactors pool, such as convection patterns, thermal mixing and stratification in operational and accidental conditions, is of primary importance and has been one of the main topics in past and present collaborative research projects. The European Scaled Pool Experiment (E-SCAPE) is a 1/6th-scale model of the MYRRHA reactor, an accelerator-driven system cooled by lead-bismuth eutectic (LBE) and under development by SCK CEN in Belgium. The E-SCAPE experimental facility has been specially designed and constructed to get insight into the pool thermal-hydraulic behaviour, producing data for validation of computer codes and supporting the design of MYRRHA. Within the ongoing European project PASCAL, NRG will perform multi-scale simulations of asymmetric flow scenarios by coupling the system code SPECTRA to a CFD code. As a first step towards a fully coupled simulation, a model of E-SCAPE in SPECTRA and Star-CCM+ are constructed separately. In this paper, these stand-alone models are compared to each other for steady state E-SCAPE experiments at forced flow and a uniform temperature of 180 C. The codes show good agreement under these conditions, which will be beneficial for a smooth and stable coupling.
