ortant to safe .control of post-accident operations. d. SPLB reviews the effects of piping failures in systems not designed to seismic Category I standards on essential systems and components. e. SPLB reviews the environmental effects of pipe rupture, such as temperature, humidity, and spray-wetting with respect to the functional performance of essential electrical equipment and instrumentation as part of its primary review responsibility for SRP Section 3.11. In addition, the SPLB will coordinate other branches evaluations that interface with the overall review of the system as follows: The Materials Engineering Branch (EMTB) reviews inservice inspection aspects of piping within protective structures or guard pipes, between containment isolation valves, as part of its primary review responsibility for SRP Section 6.6. 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 plant design for protection against postulated piping breaks outside containment, as described in the applicant's safety analysis report (SAR), will be based on General Design Criterion 4, as it relates to structures, systems and components important to safety being designed to accommodate the dynamic effects of postulated pipe rupture, including the effects of pipe whipping and discharging fluids. Acceptance is based on conformance to Branch Technical Position SPLB 3-1, attached to this SRP section. III. REVIEW PROCEDURES All the systems of concern in this section have been reviewed under other SRP sections with respect to design functions for normal operation and for the pre- vention or mitigation of accidents. The review under this SRP section does not deal with individual system design requirements necessary to assure
