s have been characterized appropriately so that there is sufficient information to conclude that the sensitivity studies performed to test the robustness of the conclusions are reasonable with respect to what is seen in current PRA practice. IV. EVALUATION OF FINDINGS The reviewer should provide documentation to conclude that the elements of the PRA required to produce the results have been performed in such a way that the PRA results are fully supportable. IV.1 Assessment of PRA Against Current Good PRA Practice The PRA elements are assessed to determine that they have been performed in a technically correct manner that conforms with current good PRA practices. This can be determined by an assessment that the PRA elements are performed consistently with the standard or peer review process as endorsed in the appendices to Regulatory Guide 1.200, or that, where a discrepancy exists, the approach used is equivalent to, or is superior to that referenced in the standard or peer review process document. Alternatively, the reviewer may rely on a demonstration that the impact on the results used in the application is not significant. IV.2 Significant Assumptions and Approximations Assessed 9 The reviewer should be satisfied that the assumptions and approximations made to address the sources of uncertainty identified as having the potential to significantly impact the particular PRA results have been characterized in an acceptable manner given the current state of knowledge, and that the characterization has taken into account the results of the peer review. V. IMPLEMENTATION This SRP is intended to be used in conjunction with, and in support of, an application-specific SRP. 1 Copies may be obtained from the General Accounting Office, 441 G Street, NW., Washington, DC 20548; phone (202)512-6000. 2 Copies may be obtained from the American Society of Mechanical Engineers, Three Park Avenue, New York, NY 10016-5990; phone (212)591-8500. 3Copies may be obtained from the
