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 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 Posi- tion C.1 of Regulatory Guide 1.115 as related to the protection of structures, systems, and components important to safety from the 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. c. NUREG/CR-0660, "Enhancement of Onsite Emergency Diesel Generator Reliability." 9.5.7-3 Rev. 2 - July 1981 d. IEEE Standard 387, as related to the design of the diesel engine lubri- cation system. e. Diesel Engine Manufacturers Association (DEMA) Standard, as related to the design of the diesel lubrication system. f. The operating pressure, temperature differentials, flow rate, and heat removal rate of the system external to the engine are in accord- ance with recommendations of tfie engine manufacturer. g. The system has been provided with sufficient protective measures to maintain the required quality of the oil during engine operation. h. Protective measures (such as relief ports) have been taken to prevent unacceptable crankcase explosions and to mitigate the consequences of such an
