of the rationale for the original structure of the affected program element. (3) Identify the emergency planning functions affected by each proposed change. Use the information in Regulatory Position 4 and the evaluation criteria in NUREG-0654 to inform this evaluation. Recognize that a proposed change can affect more than one emergency planning function. (4) Evaluate whether each proposed change would reduce the capability to perform emergency planning functions (i.e., reduce the effectiveness of the emergency plan). Refer to Regulatory Positions 1 - 4 in making these determinations. (5) Compare the NRC-approved emergency plan with the changes being considered to evaluate the reduction in effectiveness. In other words, compare the licensee’s commitment in the current NRC-approved emergency plan with what would be the commitment after the plan is modified. Plant reconfigurations enabled by other change processes (e.g., 10 CFR 50.59, 10 CFR 50.48(f), 10 CFR 50.82, 10 CFR 52.110, etc.) do not factor into this comparison. This is a yes-no decision: the change would reduce the effectiveness of the emergency plan or it would not. There are no degrees of reduction (e.g., “minor” reduction). It is inappropriate for a licensee to conclude that certain commitments made in the NRC-approved plan are no longer required and to then compare the emergency plan as modified to this conclusion, rather than the NRC-approved plan. DG-1324, Page 39 (6) Maintain the level of rigor and thoroughness in licensees’ 10 CFR 50.54(q) evaluations consistent with the scope of the proposed changes with particular emphasis placed on the risk-significant planning standards (10 CFR 50.47(b)(4), (5), (9), and (10)). The NRC would consider enforcement action for any 10 CFR 50.54(q) evaluations that are of inadequate scope and extent to reasonably assess the effect of the proposed change on the effectiveness of the emergency plan. (7) Arrange a preapplication call with NRC headquarters staff to
