hazard to occur, even when all regulatory requirements are met. In such situations, the NRC has the statutory authority to require licensee action above and beyond existing regulations to maintain the level of protection necessary to avoid undue risk to public health and safety. The use of risk information in the review of such license amendment requests is addressed in Appendix D of this SRP section. To evaluate licensee-initiated LB changes that go beyond current staff positions, the reviewers may use traditional engineering analyses as well as the risk-informed approach set forth in this SRP section. In such instances, licensees may be requested to submit supplemental risk information or traditional engineering information if such information is not already included as part of the original submittals. If risk information on the proposed LB changes is not provided, the reviewers will determine if the application can be approved on the basis of the information provided using traditional methods and will either approve or reject the application based upon this information. For those licensee-initiated LB changes that a licensee chooses (or is requested by the staff) to support with risk information, this SRP section describes the scope and content of the staff’s review by considering engineering issues and applying risk insights. 19.2-5 June 2007 Licensees submitting risk information to support changes to their LB (whether on their own initiative or at the request of the staff) should address each of the principles of risk-informed regulation discussed in Regulatory Guide 1.174. The reviewers should then determine if the licensees’ selected approaches and methods (whether quantitative or qualitative, and traditional or probabilistic), data, and criteria for considering risk are appropriate for the decision to be made. For each risk-informed application, reviewers should ensure that the proposed changes meet the following principles. (Subsections of this SRP
