m, supplemented by inleakage from the control rod drive system. If the feedwater system is inoperable, the RCIC turbine pump unit starts automatically, or the operator starts it from the control room. The water supply for the RCIC system comes from the condensate storage tank (CST), with a secondary supply from the suppression pool. The review of the RCIC system includes the system design bases, design criteria, description, and points noted below. The Reactor Systems organization is responsible for performing the technical review of the RCIC system. The specific areas of review are as follows: 1. The review of the piping and instrumentation diagrams confirms that the system is capable of performing its intended function and undergoing preoperational and operational testing. 2. The review of the degree of separation of the RCIC system from the high-pressure core spray (HPCS) system, the high-pressure coolant injection (HPCI) system, or the HPCF system addresses protection against common mode failure of redundant systems. 3. The process flow diagram review confirms that the RCIC system design parameters are consistent with expected pressures, temperatures, and flow rates. 4. The review of the complete sequence of operation confirms that the system can function as intended and that the system is capable of manual operation. 5. The system review assesses compliance with the applicable guidance of NUREG-0737. 6. Inspections, Tests, Analyses, and Acceptance Criteria (ITAAC). For design certification (DC) and combined license (COL) reviews, the staff reviews the applicant's proposed ITAAC associated with the structures, systems, and components (SSCs) related to this SRP section in accordance with SRP Section 14.3, "Inspections, Tests, Analyses, and Acceptance Criteria." The staff recognizes that the review of ITAAC cannot be completed until after the rest of this portion of the application has been reviewed against acceptance criteria contained in this SRP section.
