ADVANCED LIGHT WATER REACTORS REVIEW RESPONSIBILITIES Primary- Organization responsible for evaluating regulatory treatment of nonsafety systems in passive advanced light water reactors Secondary- Organization(s) responsible for the specific design capabilities of structures, systems, and components (SSCs) as described in the Review Interface Section of this Standard Review Plan (SRP) Organization responsible for the review of the applicants probabilistic risk assessment (PRA) Organization responsible for the review of severe accident design features Organization responsible for review of the Technical Specifications (TSs) and Short Term Availability Controls 19.3-2 Draft Rev.0 – June 2013 I. AREAS OF REVIEW This SRP pertains to the staff review of an applicant’s Regulatory Treatment of Nonsafety Systems (RTNSS) for a design certification (DC) or a combined license (COL) application. Application content guidance for DC and COL applications is provided in Section C.IV.9 of Regulatory Guide (RG) 1.206, “Combined License Applications for Nuclear Reactors,” issued June 2007. The scope of a DC review is limited to the design-specific nonsafety SSCs within the scope of the certification. For a COL application that references a DC, the staff review of RTNSS for the COL should focus on the plant-specific and site-specific nonsafety SSCs that deviate from the referenced DC. The Advanced Light Water Reactor (ALWR) Utility Requirements Document (URD) for passive plants (Volume III, Chapter 1) issued March 1999 by the Electric Power Research Institute, specifies standards concerning the design and performance of nonsafety related active systems and equipment that perform functions which support safe operation of the facility. These standards include radiation shielding to permit access after an accident, redundancy for the more probable single active failures, availability of nonsafety-related electric power, and protection against more probable hazards. The standards
