issiles. 2. General Design Criterion 4, with respect to structures housing the systems and the system components 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 componentsSSC important to safety from the 26 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 air startingcombustion air intake and exhaust system to meet independence and redundancy 27 criteria. Acceptance is based on meeting the following specific criteria: a. Regulatory Guide 1.9 as related to the design of the diesel engine combustion air intake and exhaust systems. b. Branch Technical Position ICSB-17 (PSB) as related to diesel engine combustion air intake and exhaust systems' protective interlocks during accident conditions. 28 cb .
