Advanced nuclear designs can now be licensed on their own terms

US nuclear regulators changed the rules for how they decide if a new reactor is for research or for commercial power. This means new reactor designs, especially smaller ones, will have an easier path to getting approved for commercial use.

For decades, any new nuclear reactor design, even a small research one, had to meet licensing standards written for large, commercial power plants from the 1960s. This made it expensive and slow to get new designs approved, effectively blocking innovation. This rule change means advanced reactor developers can now get their designs evaluated based on their actual purpose and scale, not an outdated standard.
