Nuclear fusion gets major push to manage rare tritium for commercial reactors

SMRTR summary

The UK Atomic Energy Authority and Italian energy firm Eni have launched RH3OVA, a joint company tackling one of fusion energy's biggest obstacles — managing tritium, an extremely rare hydrogen isotope used as reactor fuel. RH3OVA will offer engineering services across the entire tritium fuel cycle, using digital modeling tools built from real operational data to optimize fuel handling before physical systems are built, helping accelerate fusion energy's path to commercial power generation.
