"small modular reactor" | "small modular reactors"

Run against the full text of the Federal Register, published by the Office of the Federal Register, National Archives. One document counts once, however many times the words appear, and a passing mention counts the same as a whole rule.

Few documents use this exact wording. Many say SMR or advanced reactor instead, and those are not counted here.
