uction in the capability of the ECCS to perform its safety function. Acceptability is based on meeting position C2 of Regulatory Guide 1.29. B. General Design Criterion 4 as related to dynamic effects associated with flow instabilities and loads (e.g., water hammer). C. General Design Criterion 5 as it relates to structures, systems, and com- ponents 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 pres- sure boundary are not exceeded and that the core is cooled during antici- pated operational occurrences and accident conditions. 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 6.3-3 Rev. 2 - April 1984 continued effective core cooling, to permit appropriate periodic inspec- tion of important components, and to permit appropriate periodic pressure and functional testing. G. 10 CFR Part 50, §50.46, and Appendix K to 10 CFR Part 50 as it relates to the ECCS being designed so that its cooling performance is in accordance with an acceptable evaluation model. Specific acceptance criteria, Regulatory Guides, and Task Action Plan items that provide information, recommendations, and guidance and in general describe a basis acceptable to the staff that may be used to implement the requirements of the Commission regulations identified above are as
