On December 10, the NRC staff issued SECY-21-0105 seeking approval from the NRC commissioners to publish a notice of final rule that would officially replace the NRC's sensitive unclassified non-safeguards information (SUNSI) program with a Controlled Unclassified Information (CUI) program. The new rules would appear in 10 CFR Part 2, "Agency Rules of Practice and Procedure," and be consistent with the government-wide rules on CUI in 32 CFR Part 2002.

Several years ago, the US government embarked on a project to standardize federal agency programs—including the NRC’s—for managing unclassified-but-sensitive information. At the NRC, this government-wide Controlled Unclassified Information (CUI) program is intended to replace the agency’s Sensitive Unclassified Non-Safeguards Information (SUNSI) program.
