Scaling Analysis for the European Heavy Liquid Metal Scaled Pool Facility Escape

Abstract

The understanding of the thermal-hydraulic phenomena occurring in the reactor pool is a critical issue in the design of the MYRRHA system, the European Technology Pilot Plant for the Lead Fast Reactor. The E-SCAPE facility is a thermal-hydraulic scale model of the MYRRHA reactor using lead-bismuth as coolant. Non-dimensional analysis and CFD simulations are used to determine the scaling factors and transposition of the experimental results to the real scale situation. The joint efforts of SCK•CEN and NRG within the European project THINS in applying CFD to fix the design parameters of E-SCAPE is reported.
