SECY-93-087, “Policy, Technical, and Licensing Issues Pertaining to Evolutionary and Advanced Light-Water Reactor Designs,” ADAMS Accession No. ML003708021, dated April 2, 1993, and the related SRM, ADAMS Accession No. ML003708056, dated July 21, 1993. 19.0-10 Draft Revision 3 – September 2012 8. SECY-93-087 and the Commission’s SRM provide guidance for meeting the deterministic containment performance goal (CPG) in the evaluation of the passive Advanced Light Water Reactors (ALWRs) as a complement to the conditional containment failure probability (CCFP) approach. The expectation in SECY-93-087 with respect to the deterministic containment performance assessment is as follows: The containment should maintain its role as a reliable, leaktight barrier (e.g., by ensuring that containment stresses do not exceed American Society of Mechanical Engineers (ASME) Service Level C limits for metal containment or factored load category
