Fusion’s Neutron Hammer: Engineering for the Future of Energy

As fusion energy nears commercial reality, engineers face a powerful adversary: neutron flux. First-gen reactors like SPARC may require annual replacement of critical components due to intense bombardment. But next-gen designs like ARC are rewriting the playbook.
ARC introduces FLiBe liquid blankets — a game-changer that:
• Shields reactor materials from neutron damage
• Breeds tritium for fuel
• Transfers heat efficiently at high temps

Yet FLiBe brings its own challenges: corrosion, tritium management, and material compatibility at ~850°C. Solutions like HELICOFLEX® TEXEAL® seals and SiC composites are pushing the boundaries of reactor design.

With ARC, Xcimer Energy, and MoltexFLEX exploring FLiBe, the fusion industry is pivoting toward durable, liquid-blanket architectures. The question now: can we engineer reactor cores to withstand their own power?
