mer) with respect to impairment of the required functions of auxiliary cooling systems during normal plant operations, and under upset or accident conditions. Acceptance will be based on the following commitments by the applicant: a. Vents shall be provided for venting components and piping at high points in liquid filled systems which is normally idle and in which voids could occur. These vents should be located for ease of operation and testing on a periodic basis. b. Operating and maintenance procedures shall be reviewed by the applicant to assure 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 design features which permit inservice inspection of safety-related components and equipment. 9.2.2-10 Rev. 2 - April 1984 - - . 6. The applicant has met the requirements of
