Nuclear Heat Workshop

ARPA-E hosted a workshop on Nuclear Heat & Power for Industrial Process Applications on May 30-June 1, 2023 in Houston, TX.

The event convened technical experts and thought leaders to discuss critical technology needs and opportunities for decarbonizing industrial processes by coupling these processes with nuclear heat and power. The workshop included technical and market focused presentations, facilitated breakout groups, and networking opportunities with the overarching goal of identifying disruptive R&D pathways to integrate nuclear heat and power with industrial processes.

Participants had the opportunity to discuss progress on advanced nuclear reactors, economic and regulatory drivers, and process co-designs and co-optimizations, identify key technical challenges, propose potential solutions, network with stakeholders, and share experiences in the field.
