25% of NRC 10 CFR 73.54 you already have
NIST SP 800-171A Rev 3 already covers about 25% of NRC 10 CFR 73.54, leaving
6 of 8 controls as genuinely new work.
Already covered 2
Likely covered 0
New work 6
What is genuinely new work
Nothing in NIST SP 800-171A Rev 3 reaches these. This is the list to scope.

How this is calculated
Already covered means a mapping runs from a control in NIST SP 800-171A Rev 3 to that control. Likely
covered means no direct mapping exists but both frameworks map to the same control in a third
standard. New work means neither. We keep those separate rather than adding them into one
friendlier number, because blending them would present a two-hop inference as a verified
fact.
Coverage is not symmetric.
Run it the other way and you will get a
different number; both are correct.
From 332,959 cross-framework control
mappings across 723 frameworks, 531 of them verified against
their source documents. It does not tell you that you are compliant: a mapped control means
the two standards ask for the same thing, not that you have done it.
