WGAMA / Thermal-Hydraulics Specialists Meeting


13th - 17th December 2021 

CIEMAT (Madrid)

  • Cabecera

"A thermal-hydraulic Specialists Meeting organized by the Working Group of Analysis and Management of Accidents (WGAMA) of Committee on the Safety of Nuclear Installations (CSNI) - Nuclear Energy Agency (NEA) of Organization for Economic Cooperation and Development (OECD) - will be held in CIEMAT Headquarters in Madrid.

Aimed to discuss the recent achievements and the remaining needs of safety research in nuclear reactor thermalhydraulics design and safety, the Specialists Meeting is mostly focused on water cooled reactors and the capability of system codes (3D CFD modelling not excluded, though) and associated uncertainty quantification to capture the key phenomena occurring during transients and accidents: the entire spectrum of activities ranging from basic thermal-hydraulics to application of the Best Estimate Plus Uncertainty (BEPU) approach in licensing is under consideration.

Coupling of thermal-hydraulics with areas like neutron physics, nuclear fuel chemistry and thermo-mechanics, risk assessment and severe accidents (both in reactor and in spent fuel pools) is also within the Specialist Meeting scope. The key (ambitious) objective is streamlining of directions for new activities which, in the following decades, may stepwise improve fundamental understanding of thermal-hydraulics and model capabilities in applications."
