33rd European Fusion Programme Workshop

3 Feb 2026, 08:30 → 5 Feb 2026, 14:00 Europe/Berlin

2026 EFPW Workshop on Heat and Particle Exhaust in a Fusion Power Plant

 

The 33rd European Fusion Programme Workshop (EFPW33) will take place in Zagreb, Croatia, at the Hotel Sheraton, from 3-5 February 2026 with the possibility of Video Conference.

The title of the workshop is “Heat and particle exhaust in a fusion power plant”.

The STAC has agreed on the following session topics:

• Exhaust requirements for a fusion power plant

• Exhaust and SOL-transport modelling

• Exhaust in different operational regimes

• Divertor designs and configurations

• Power exhaust technology
