t, in part, by providing in the CVCS appropriately designed venting and draining closed systems to confine the radioactivity associated with the effluents. 7. 10 CFR 52.47(a)(1)(vi) specifies that the application of a design certification should contain proposed ITAAC necessary and sufficient to assure the plant is built and will operate in accordance with the design certification. 10 CFR 52.97(b)(1) specifies that the COL identifies the ITAAC necessary and sufficient to assure that the facility has been constructed and will be operated in conformity with the license. SRP 14.3 provides guidance for reviewing the ITAAC. The requirements of 10 CFR 52.47(a)(1)(vi) and 10 CFR 52.97(b)(1) will be met, in part, by identifying inspections, tests, analyses, and acceptance criteria of the top-level design features of the CVCS in the design certification application and the combined license, respectively. Technical Rationale: The technical rationale for application of these acceptance criteria to the areas of review addressed by this SRP section is discussed in the following paragraphs: 1. GDC 1 requires that structures, systems, and components (SSCs) important to safety be designed, fabricated, erected and tested to quality standards commensurate with the importance of the safety functions to be performed. The CVCS may be important to safety in that: 1) the CVCS may be capable of emergency boration with boron concentration that exceeds the requirements for safe shutdown during a safety injection to a RCS; 2) the CVCS may provide a means of makeup for the RCS coolant inventory in the event of small leaks; 3) portions of the CVCS may provide seal water to the reactor coolant pump (RCP) components important to safety; 4) the CVCS may be capable of borating the RCS to a safe cold shutdown condition; 5) the CVCS is relied upon to control RCS water chemistry to maintain the integrity of the RCS pressure boundary; 6) through connections to the RCS a CVCS failure could adversely
