fication reports, and their locations. Functional specifica- tions for active valve assemblies should confirm to the Regulatory Position of Regulatory Guide 1.148. e. Description of the required loads and their intensities for which the equipment must be qualified. f. If qualification by test, identification of the test methods and procedures, important test parameters and a summary of the test results. g. If qualification by analysis, identification of the analysis methods and assumptions and comparisons between the calculated and allowable stresses and deflections for critical elements. h. The natural frequency (or frequencies) of the equipment. i. Identification of whether the equipment may be affected by vibration fatigue cycle effects and a description of the methods and criteria used to qualify the equipment for such loading conditions. J. Indicate whether the equipment has met the qualification requirements. k. Availability for inspection, i.e., identify whether the equipment is already installed. 1. A compilation of the required response spectra (or time history) and corresponding damping for each seismic and dynamic load specified for the equipment together with all other loads considered in the qualification and the method of combining all loads. 4. General Design Criterion 14 of Appendix A to 10 CFR 50 requires, in part, that the reactor coolant pressure boundary shall be designed, fabricated, erected, and tested so as to have an extremely low probability of abnormal leakage. General Design Criterion 30 further requires, in part, that 3.10-9 Rev, 2 - July 1981 components which are part of the reactor coolant pressure boundary shall be designed , fabricated, erected, and tested to the highest quality standards practical. In order to satisfy these requirements, the qualification program for valves that are part of the reactor coolant pressure boundary should include testing or testing and analyses that demonstrate these valves will not experience any
