urbine missiles. 9.5.5-5 DRAFT Rev. 3 - April 1996 3. General Design Criterion 5, as related to the capability of 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 cooling water system to meet independence and redundancy criteria, and General Design Criterion 44, to assure: •a. The capability to transfer heat from systems and components to a heat sink under 30 transient or accident conditions. •b. Redundancy of components so that under accident conditions the safety function 31 can be performed assuming a single active component failure. •c. The capability to isolate components of the system or piping, if required to 32 maintain the system safety function. To meet the requirements of these regulations the following guidance and positions are used: a. Regulatory Guide 1.9, as related to the design of the diesel cooling water system. b. Branch Technical Position ICSB-17 (PSB) as related to engine cooling water protective interlocks during accident conditions.33 cb. NUREG/CR-0660, "Enhancement of Onsite Emergency Diesel Generator 34 Reliability." (Reference 13) 35 dc. ANSI/IEEE Stdandard 387 as related to the design of the diesel engine cooling 36 37 water system (Reference 14).38 ed. Diesel Engine Manufacturers Association (DEMA) Standard (Reference 15) , as 39 40 related to the design of the engine cooling water system. 5. General Design Criterion 45, as related to design provisions to permit periodic inspection of safety-related components and equipment of the system. 6. General Design Criterion 46, as related to design provisions to permit appropriate functional testing of safety-related systems or components to assure structural integrity and leaktightness, operability and performance of active components, and the capability of the system to function as intended under accident conditions.
