solation of interconnected trains in the event of unusual conditions such as low pressures in the reactor auxiliary cooling water system or drawing low current for safety-related pumps. The review for Fire Protection, Techni- cal Specifications, and Quality Assurance are coordinated and performed by the Plant Systems Branch, Technical Specification Coordination Branch and the Facility Operations Branch as part of their primary review responsibility for I SRP Sections 9.5.1, 16.0, and 17.0, respectively. For those areas of review identified above as being reviewed as part of the primary review responsibility of other branches, the acceptance criteria neces- sary for the review and their methods of application are contained in the referenced SRP section of the corresponding primary branch. II. ACCEPTANCE CRITERIA Acceptability of the designs of cooling water systems as described in the applicant's Safety Analysis Report (SAR), including related sections of Chapters 2 and 3 of the SAR, is based on specific general design criteria and regulatory guides, and on independent calculations and staff judgments with respect to system functions and component selection. The design of a CWS is acceptable if the integrated system design is in accordance with the following requirements and recommendations: 1. General Design Criterion 2, as related to structures housing the system and the system itself being capable of withstanding the effects of 9.2.2-3 Rev. 3 - June 1986 earthquakes. Acceptance is based on meeting the guidance of Regulatory Guide 1.29, Position C.1 for safety-related portions and Position C.2 for nonsafety-related portions. 2. General Design Criterion 4, as related to effects of missiles inside and outside of containment, effects of pipe whip, jets and environmental con- ditions resulting from high and moderate energy line breaks and dynamic effects associated with flow instabilities and attendant loads (i.e., water hammer) during normal plant operation as well as
