The European Thermal Hydraulics Community (ETHC) is the first Topical Community established under the umbrella of SNETP and is now pioneering to find its position in the European nuclear landscape.

The ETHC aims to establish, stimulate, share and maintain high-level knowledge and expertise in all areas of nuclear thermal hydraulics. The initiative was been taken by Katrien van Tichelen (SCK CEN, Belgium) and Ferry Roelofs (NRG PALLAS, Netherlands). The initial ETHC council has been formed and consists apart from Katrien and Ferry of Sanjeev Gupta (Framatome, Germany), Pierre Ruyer (ASNR, France), and Stefano Lorenzi (PoliMi, Italy).

The community aims to reach its goals by:

  • Bringing together experts, students and young professionals,
  • Stimulating networking and mobility,
  • Sharing resources and setting up collaborations,
  • Facilitating knowledge management, expansion, and development
  • Connecting students and (young) professionals with SNETP and other international organizations (e.g. ANS THD)

The European Thermal Hydraulics Community (ETHC) successfully hosted its second Lunchinar on “Multiphysics simulation of advanced nuclear reactors” with over 100 participants on 29 October, featuring expert talks by

  • Dr. Antoine Gerschenfeld (Stellaria, France)
  • Prof. Stefano Lorenzi (PoliMi, Italy)
  • Prof. April Novak (University of Illinois, USA)

ETHC is Europe’s premier community advancing thermal hydraulics research for safe and innovative nuclear technology.
