nctions are not compromised. D. Whether a single VWS failure results in fuel damage or reactor coolant leakage in excess of normal coolant-makeup capability. Sources of single failure include, but are not limited to, operator error, spurious activation of a valve operator, and loss of a cooling water pump. E. Whether a moderate-energy leakage crack or an accident from a VWS piping failure results in excessive fuel damage or reactor coolant leakage in excess of normal coolant makeup capability. A single active failure is considered in evaluations of the consequences of this accident. Moderate leakage cracks are determined in accordance with the guidelines of Branch Technical Position (BTP) 3-3, “Protection Against Postulated Piping Failures in Fluid Systems Outside Containment.” 6. GDC 45, as to design provisions for appropriate periodic inspection of important components, such as heat exchanges and piping, to assure the integrity and capability of the system. 7. GDC 46 as to design provisions to permit appropriate periodic pressure and functional test to assure; A. The structure and leaktight integrity of VWS components. B. The operability and the performance of active components of the system. C. The operability of the system as a whole and, under conditions as close to design as practical, the performance of the full operational sequence that brings the system into operation for reactor shutdown and for loss-of-coolant accidents (LOCAs), including operation of applicable portions of the protection system and the transfer between normal and emergency power sources. 8. Title 10 of the Code of Federal Regulations (10 CFR) 52.47(b)(1), which requires that a DC application contain the proposed ITAAC that are necessary and sufficient to provide reasonable assurance that, if the inspections, tests, and analyses are performed and the acceptance criteria met, a facility that incorporates the DC has been constructed and will be operated in conformity with the DC, the
