SRP 19-34 IV. EVALUATION FINDINGS The results of the reviewers' evaluation should reflect a consistent and scrutable integration of the probabilistic considerations and traditional engineering considerations provided by the licensee or applicant and developed independently by the reviewers. To reach a finding of acceptability, reviewers will generally need to show that in light of a small or non-existent increase in risk and a reduced level of conservatism, defense-in-depth and sufficient safety margins are maintained.
