e located for ease of operation and testing on a periodic basis. b. Consideration will be given to voiding which can occur following pump shutdown, or during standby. If the system design is such that voiding could occur after pump shutdown or during standby, means should be 72 provided for a slow system fill upon pump start to avoid water hammer or the system should be designed to maintain function following an inadvertent water hammer occurrence. c. Operating and maintenance procedures shall be reviewed by the applicant to assure ensure that adequate measures are taken to avoid water hammer due to voided line conditions. 3. The applicant has met the requirements of General Design Criterion 5 with respect to sharing of structures, systems and components by demonstrating that such sharing does not significantly impair the ability of the reactor auxiliary cooling water systems to perform their safety function, including, in the event of an accident in one unit, an orderly shutdown and cooldown of the remaining units. 4. The applicant has met the requirements of General Design Criterion 44 with respect to cooling water by providing a system to transfer heat from structures, systems and components important to safety to an ultimate heat sink. The applicant has demonstrated that the reactor auxiliary cooling water systems can transfer the combined heat load of these structures, systems and components under normal operating and accident conditions assuming loss of offsite power and a single failure, and that portions of the system can be isolated so that the safety function of the system will not be compromised. 5. The applicant has met the requirements of General Design Criterion 45 with respect to inspection of cooling water systems by providing reactor auxiliary cooling water systems 9.2.2-17 DRAFT Rev. 4 - April 1996 design features which permit inservice inspection of safety-related components and equipment. 6. The applicant has met the requirements of General
