Content:
the reactor coolant pressure boundary inside containment and the resulting discharging fluid provide adequate assurance that design basis loss-of-coolant accidents will not be aggravated by sequential failures of safety-related piping, and emergency core cooling system performance will not be degraded by these dynamic effects. 3. The proposed piping and restraint arrangement and applicable design considerations for high- and moderate-energy fluid systems inside and outside of containment, including the reactor coolant pressure boundary, will provide adequate assurance that the 3.6.2-8 Rev. 1 - July 1981 structures, systems and components important to safety that are in close proximity to the postulated pipe rupture will be pro- tected. The design will be of a nature to mitigate the conse- quences of pipe ruptures so that the reactor can be safely shut down and maintained in a safe shutdown condition in the event of a postulated rupture of a high or moderate energy piping system inside or outside of containment. V. IMPLEMENTATION The following is intended to provide guidance to applicants and licensees regarding the NRC staff's plans for using this SRP section. Except in those cases in which the applicant proposes an acceptable alternative method for complying with specified portions of the Commission's regulations, the method described herein will be used by the staff in its evaluation of conformance with Commission regulations. For protection against postulated pipe ruptures outside containment, Reference 2 includes the area.of concern in this position and has been used for those plants for which construction permit applications were tendered before July 1, 1973. Reference 3 specifically emphasizes protection via plant arrangement and layouts utilizing the concept of physical separation to the extent practical and has been used for those plants for which construction permit applications were tendered after July 1, 1973 and before July 1, 1975 as specified in
