## Regulations

NRC's regulations are found in Chapter I, "Nuclear Regulatory Commission," of Title 10, "Energy," of the Code of Federal Regulations (CFR). Chapter I is divided into Parts 1 through 199. The following are the principal parts governing emergency preparedness for nuclear power plants:
        - 10 CFR 50.47 , "Emergency Plans," includes the 16 planning standards of 50.47(b) and the "Realism Rule" recognizing that State and local government officials do their best to protect the public health and safety in 50.47(c)
        - 10 CFR 50.160 , "Emergency Preparedness for small modular reactors, non-light-water reactors, and non-power production or utilization facilities," describes a licensee’s required emergency response capabilities.
        - Appendix E to 10 CFR Part 50 , "Emergency Planning and Preparedness for Production and Utilization Facilities," describes information needed to demonstrate compliance with emergency preparedness requirements in Section IV, "Content of Emergency Plans"
        - 10 CFR 50.54(q) , requirements for following and maintaining in effect emergency plans
