ructures, systems, and components (SSCs) whose failure could cause an unacceptable reduction in the 44 capability of the ECCS to perform its safety function. Acceptability is based on meeting position C2 of Regulatory Guide 1.29.45 B. General Design Criterion 4 as related to dynamic effects associated with flow instabilities and loads (e.g., water hammer). DRAFT Rev. 3 - April 1996 6.3-6 C. General Design Criterion 5 as it relates to structures, systems, and components SSCs46 important to safety shall not be shared among nuclear power units unless it can be demonstrated that sharing will not impair their ability to perform their safety function. D. General Design Criterion 17 as it relates to the design of the ECCS having sufficient capacity and capability to assure that specified acceptable fuel design limits and the design conditions of the reactor coolant pressure boundary are not exceeded during anticipated operational occurrences and that the core is cooled during anticipated operational occurrences and accident conditions. 47 E. General Design Criterion 27 as it relates to the system design having the capability to assure that under postulated accident conditions and with appropriate margin for stuck rods, the capability to cool the core is maintained. F. General Design Criteria 35, 36, and 37 as they relate to the ECCS being designed to provide an abundance of core cooling to transfer heat from the core at a rate so that fuel and clad damage will not interfere with continued effective core cooling, to permit appropriate periodic inspection of important components, and to permit appropriate periodic pressure and functional testing. G. 10 CFR Part 50, §50.46, in regard to the ECCS being designed so that its cooling performance is in accordance with an acceptable evaluation model; alternatively, an ECCS evaluation model may be developed in conformance with and Appendix K to 10 CFR Part 50. as it relates to the ECCS being designed so that its cooling performance
