t for avoidance of water hammer or that the system be designed to maintain functioning following an inadvertent water hammer occurrence. c. operating and maintenance procedures will be reviewed by the applicant to assure that sufficient measures have been taken for avoiding water hammer (e.g., rapid fill due to pump start, periodic fill and vent checks, avoidance of sudden valve movement, or realignment). 3. The applicant has met the requirements of General Design Criterion 5 with respect to sharing of structures, systems and components by 9.2.1-8 Rev. 4 - June 1986 demonstrating that such sharing does not significantly impair the ability of the service water system to perform its safety function, including in the event of an accident in one unit, an orderly shut- down 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 service water system 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 sys- tem will not be compromised. The applicant has also met task action plan items II.K.1-C.1.22 of NUREG-0694 and II.K.1.22 of NUREG 0718 in meeting General Design Criterion 4. 5. The applicant has met the requirements of General Design Criterion 45 with respect to inspection of cooling water systems by providing a service water system which permits inservice inspection of safety- related components and equipment. 6. The applicant has met the requirements of General Design Criterion 45 with respect to testing of cooling water systems by providing a ser- vice water system design which permits operational functional testing
