01 · The brief
Plain-English summaryWhat this bill actually does

This bill raises statutory size thresholds for small modular reactors (SMRs) from 300 to 500 electrical megawatts and aligns related definitions. It directs the NRC and DOE to update guidance, prevents DOE from excluding projects whose single-unit output falls between 50 and 500 MW from certain grid-scale funding, and creates a DOE-led working group to promote SMR commercialization, manufacturing, workforce readiness, and competitiveness, with annual reports through 2030.

Why people may split

Liberals worry about waste, cost, and diversion from renewables

Watch point

Relative to its intended legislative type, this bill is a concise substantive statutory amendment package that also establishes a focused interagency working group and reporting requirement.
