This revision incorporates guidance and recommendations from Regulatory Guide (RG) 1.221, "Design-Basis Hurricane and Hurricane Missiles for Nuclear Power Plants," and Interim Staff Guidance DC/COL- ISG-024, "Implementation of Regulatory Guide 1.221 on Design-Basis Hurricane and Hurricane Missiles."

The revision also incorporates guidance on regulatory treatment of nonsafety systems.
