iewing the engineering (or other pertinent) analysis and data that identify the safety margins and plant design and/or activities conducted to preserve those margins. If exemptions from regulations or other forms of relief are needed to implement the licensee’s proposed 19.2-7 June 2007 change, reviewers should ensure that the appropriate requests accompany the licensee’s submittal. Reviewers should also verify that the licensee has identified and appropriately used available information reflecting traditional engineering concepts and principles. The non-PRA sources of information that should be examined to support the evaluation of safety significance include the safety insights developed in licensing documents such as the FSAR, as well as the bases for the plant’s Technical Specifications, which may include AOTs, limiting conditions for operation (LCOs), and surveillance requirements (SRs). Where available, plant-specific data and operational information should be factored into the definition of the proposed change. Reviewers should consider the way in which the issues at hand are reflected in operational data. Useful insights from plant-specific operating experience can also be obtained from inspections that follow incidents at the facility, including incident investigation and augmented team inspections conducted by the NRC, incident assessments documented in significant operating event reports prepared by the Institute of Nuclear Power Operations (INPO), licensee follow-up investigations, and routine inspections by NRC resident inspectors. Inspection results can provide valuable qualitative insights in such areas as human performance, management controls, adequacy of procedures, and root causes of events, which are often difficult to treat with precision in a PRA. Finally, as part of the initial review of the licensing amendment, reviewers should determine if the submittal adequately characterizes the impact of the proposed change (specifically, if the
