Abstract
Abrupt collapse of vapour bubbles at high Jakob number is the leading physical phenomenon of the simulated chugging sodium boiling regime occurring during unprotected loss of flow (ULOF) accident in Sodium Fast Reactor (SFR) low-void core designs. The ESFR-SMART Horizon 2020 project aims at a better understanding and simulation of chugging conditions. Therefore, the small-scale two-phase flow facility “CHUG” for the mock-up of sodium boiling using water as sodium simulant has been designed at Paul Scherrer Institut (PSI) and built at the Laboratory of Reactor Systems behaviour at EPF Lausanne. CHUG consists of an acrylic glass test section filled with water at a...
