Project FORTE Phase 2

Phase 2 focuses on the industrial application and commercialisation of the UK predictive capability for passive safety arguments. This project covers single phase heat transfer and natural convection for all advanced nuclear technologies (water, high temperature gas, liquid metal and molten salt).
