Framework overlap

Does BSI IT-Grundschutz cover US NRC 10 CFR 73.54?

You hold BSI IT-Grundschutz and have been told to do US NRC 10 CFR 73.54. Here is how much overlaps, control by control.

20% of US NRC 10 CFR 73.54 you already have

BSI IT-Grundschutz already covers about 20% of US NRC 10 CFR 73.54, leaving 4 of 5 controls as genuinely new work.

Already covered 0 Likely covered 1 New work 4

No control in BSI IT-Grundschutz maps directly to one in US NRC 10 CFR 73.54. Everything counted as covered is covered because both map to the same third standard, which is what a crosswalk is, but it is an inference rather than a lookup.

What is genuinely new work

Nothing in BSI IT-Grundschutz reaches these. This is the list to scope.

USNRCCYBER-1
High Assurance Standard and Scope
USNRCCYBER-2
Critical Digital Asset (CDA) Identification and Protection
USNRCCYBER-3
Cyber Security Plan and Programme
USNRCCYBER-5
Incident Response, Reporting, NRC Cooperation

Defense-in-Depth and Technical Controls

How this is calculated

Already covered means a mapping runs from a control in BSI IT-Grundschutz 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.
