ent of the emergency preparedness cornerstone of the ROP, a group of emergency preparedness subject matter experts, including NRC staff and industry stakeholders, with input from the public, developed the emergency preparedness significance determination process, Inspection Manual Chapter 0609, “Significance Determination Process,” Appendix B, “Emergency Preparedness Significance Determination Process,” (Ref. 14). During the development, the group determined that the planning standard language would not be sufficiently clear for use as a basis for significance determination and instead developed a series of planning standard functions. These planning standard functions are paraphrases of the planning standards in terms of the significant functions that need to be accomplished, or the capabilities that need to be in place, to maintain the effectiveness of the emergency plan and the emergency response capability. Within the emergency preparedness cornerstone, the significance of findings depends on whether the planning standards cannot be accomplished (i.e., loss of planning standard function) or can be accomplished only in a degraded manner (i.e., degraded planning standard function) with greater significance accorded to findings associated with certain planning standards deemed to have greater public safety significance.2 Any degradation, or loss, of a planning standard function, renamed as an “emergency planning function,” corresponds to a reduction in effectiveness (defined below). 3.3 Program Element a. “Program element” means the items that comprise the implementation aspects of an emergency planning function. These items correspond to the evaluation criteria in NUREG-0654 (or other alternative methods for which the licensee obtained approval) that identify specific acceptable methods for complying with an emergency planning function. 2 These standards are 10 CFR 50.47(b)(4) for classification, 10 CFR 50.47(b)(5) for notification, 10 CFR
