n an integrated response capability that includes strategies and guidelines to mitigate a BDBEE. Related Guidance • JLD-ISG-2012-01, “Compliance with Order EA-12-049, Order Modifying Licenses with Regard to Requirements for Mitigation Strategies for Beyond-Design-Basis External Events,” Rev. 0, was issued August 29, 2012 (Ref. 4). This interim staff guidance (ISG) endorses, with clarifications, the methodologies described in NEI 12-06, Rev. 0 (Ref. 5) as one acceptable method of demonstrating compliance with NRC Order EA-12-049. JLD-ISG-2012-01 is superseded and replaced by this RG. Purpose of Regulatory Guides The NRC issues RGs to describe to the public methods that the NRC considers acceptable for use in implementing specific parts of the agency’s regulations, to explain techniques that the NRC uses in evaluating specific problems or postulated accidents, and to provide guidance to applicants. Regulatory guides are not substitutes for regulations and compliance with them is not required. Methods and solutions that differ from those set forth in RGs will be deemed acceptable if they provide a basis for the findings required for the issuance or continuance of a permit or license by the Commission. Paperwork Reduction Act This RG contains information collection requirements covered by 10 CFR 50 and 10 CFR Part 52, “Licenses, Certifications, and Approvals for Nuclear Power Plants,” (Ref. 6) that the Office of Management and Budget (OMB) approved under OMB control numbers 3150-0011 and 3150-151 respectively. The NRC may neither conduct nor sponsor, and a person is not required to respond to, an information collection request or requirement unless the requesting document displays a currently valid OMB control number.
