Nuclear Regulators Tighten Security Guidance for Nonpower Facilities
Published Date: 6/12/2026

Summary
The Nuclear Regulatory Commission just rolled out new security rules for folks running or applying to run non-power nuclear facilities. Starting June 12, 2026, these places must have clear, detailed security plans to keep things safe and sound. If you’re involved, expect to update your security game soon—this could mean some extra work and costs, but it’s all about keeping everyone secure!

Clarifies security plan contents for NPUFs
The NRC issued Interim Staff Guidance DANU-ISG-2026-01 that clarifies what must be included in a physical security plan for a non-power production or utilization facility (NPUF). Physical security plans are a required part of an operating license application under 10 CFR part 50, and NRC staff will use this guidance when reviewing new NPUF applications and changes to licensed NPUF security programs. The guidance is effective June 12, 2026.
Security-related guidance withheld; access rules
The NRC is withholding the full DANU-ISG-2026-01 from public release because it contains security-related information. Persons with a need to know, including NPUF licensees and applicants, can access the full document through the NRC project manager, and a publicly available redacted version is in ADAMS (ML26140A323).
