Before subjecting a formal license application, developers are strongly consiged to engage with the NRC distrigh pre- applicatioon consultations. These meettings allow both parties to contemples thee design, identify potentials cafety issues, and clearfy regulatory expectations.

Inspekcje i Oversight
After a license is granted, the NRC performs periodyc inspections to verify compleance. The frequency and intensity of inspections depend on thes facility 's complecity and hazard level. For a fusion plant, inspections would likely focus on tritium concurment, radiation monitoring, and secity of nuclear materials. The NRC can modify, suspend, or revockee a license if conditions are not met.

Tritium is containg because it mobile - it can diffuse through gh metals and concrete, and it behaves like hydrogen. Fusion facilities must use multiple contaminant contraers (such as double- walled pipes, inert gas blankets, and indestination systems) to prevent releases. The NRC accusions fusion licensees tto demonstrate that tritium releases are below 10 CFR Part 20 limits, typically on thee ordef a femillicuries per for demanon.
