the division directors responsible for probabilistic safety assessment, the technical issue and the regulatory requirements in question, and licensing project management, as well as the Office of the General Counsel. Review by the Risk-Informed Licensing Panel (RILP) should be considered for this purpose. The need to elevate SRP 19-D4 the issue to a higher management level or to inform the Commission should be specifically addressed by the RILP if a special circumstance is determined to exist. The RILP should ensure that the burden imposed on the licensee in responding to risk questions raised by the NRC is justified in view of the potential safety significance of the issue to be addressed in the requested information. If a licensee does not choose to address risk, the reviewers should not issue the requested amendment until they have sufficiently assessed the risk implications to determine that there is reasonable assurance that the public health and safety will be adequately protected if the amendment request is approved. A licensee’s decision not to submit requested information could impede the staff’s review and could also prevent the reviewers from reaching a finding that there is reasonable assurance of adequate protection. A licensee’s failure to submit requested information could also be a basis for rejection pursuant to 10 CFR 2.108. Evaluation Findings The numerical guidance for CDF and LERF and the safety principles provided in Regulatory Guide 1.174 are intended to provide a basis for finding that there is reasonable assurance of adequate protection. Therefore, situations that exceed these values or violate the other principles would constitute a trigger point at which questions are raised as to whether the proposed change provides reasonable assurance of adequate protection. A more in-depth assessment of the special circumstances, the safety principles, and the issues identified for management attention in Section 2.2.6 of Regulatory Guide 1.174
