assification level and the implementation of the licensee’s emergency plan. An emergency is not based on a single accident sequence but instead on the spectrum of accidents addressed in the planning basis described in NUREG-0654. As noted above, “capabilities” means the capacity to carry out the response actions identified in the emergency plan to meet the emergency planning functions 4 Reporting requirements may apply, see 10 CFR 50.72(b)(3)(xiii) DG-1324, Page 19 (e.g., the ability to augment onshift personnel in a timely manner, generate timely and accurate PARs, complete notifications within 15 minutes, and maintain a protracted response). c. The linkage between a proposed change and a possible degradation in the licensee’s capability may not always be obvious, and many such decisions would involve a significant evaluation by the reviewer. 4. Emergency Planning Functions a. Regulatory Position 3.2 defines emergency planning functions. Regulatory Position 4 provides the individual emergency planning functions along with explanatory guidance. Regulatory Position 4 provides and explains examples of changes that could require prior NRC approval and those that would generally not require prior NRC approval. Licensees should not view these examples as being all inclusive or exclusive; instead, they should use them to inform decisions involving various changes under consideration. Site-specific situations may possibly make a particular example inapplicable to that site. Even if a particular example completely encompasses the change under consideration, the licensee’s 10 CFR 50.54(q) evaluation must explain why the site-specific implementation of the change would not reduce the effectiveness of the emergency plan, as compared to the current NRC-approved plan, for that particular site. Such an analysis cannot simply cross-reference an example in this guide. b. In evaluating proposed plan changes, the licensee may need to consider the effect of the proposed
