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 of the appendix to Regulatory Guide 1.117, as related to the protection of structures, systems, and components (SSC)28 important to safety from the effects of tornado missiles. 2. General Design Criterion 4, with respect to structures housing the system and the system itself being capable of withstanding the effects of external missiles and internally generated missiles, pipe whip, and jet impingement forces associated with pipe breaks. Acceptance is based on meeting Position C.1 of Regulatory Guide 1.115 as related to the protection of structures, systems, and components SSC important to safety from the 29 effects of turbine missiles. 3. General Design Criterion 5, as related to shared systems and components important to safety being capable of performing required safety functions. 4. General Design Criterion 17, as related to the capability of the diesel engine lubrication system to meet independence and redundancy criteria. Acceptance is based on meeting the following specific criteria: a. Regulatory Guide 1.9, as related to the design of the diesel engine systems. b. Branch Technical Position ICSB-17 (PSB), as related to diesel engine lubrication systems' protective interlocks during accident conditions.30 cb .
