tructures housing the system to withstand the effects of natural phenomena such as earthquakes, tornadoes, hurricanes, and floods, as established in Chapters 2 and 3 of the SAR. Acceptance is based on meeting Position 13 to the appendix to Regulatory Guide 1.117, as related to the protection of structures, systems, and components important to safety from the effects of tornado missiles. 2. General Design Criterion 4, with respect to structures housing the systems and the system itself being capable of withstanding the effects of exter- nally and internally generated missiles, pipe whip, and jet impingement 9.5.6-2 Rev. 2 - July 1981 forces associated with pipe breaks. Acceptance is based on meeting Posi- tion C.1 of Regulatory Guide 1.115 as related to the protection of struc- tures, systems, and components important to safety from the effects of turbine missiles. 3. General Design Criterion 5, as related to the capability of shared systems and components important to safety to perform required safety functions. 4. General Design Criterion 17 as related to the capability of the diesel engine air starting system to meet independence and redundancy criteria. Specific criteria and guidance necessary to meet the relevant requirements of GDC'17 are as follows: a. Regulatory Guide 1.9 as related to the design of the diesel air start- ing systems. b. Branch Technical Position ICSB-17 (PSB) as related to diesel engine air starting systems' protective interlocks during accident conditions. c. NUREG/CR-0660 "Enhancement of Onsite Emergency Diesel Generator Reliability." d. IEEE Standard 387 as related to the design of the diesel engine air starting system. e. Diesel Engine Manufacturers Association (DEMA) Standard as related to the design of the diesel air starting system. f. Each diesel engine should be provided with a dedicated air starting system consisting of an air compressor, an air dryer, one or more air receiver(s), piping, injection lines and valves, and devices to
