CFR Part: 
CFR Title: 

Content:
c Category I design requirements to the first seismic restraint beyond the defined boundaries.(i.e., the piping from the safety and relief valves to the first downstream restraint). 2. The applicant's design meets the requirements of General Design Cri- terion 4 as it relates to protection of safety-related equipment from adverse environmental affects and from missiles generated by rupture disc failure. This criterion is met since the system is designed to prevent steam or water release to containment under any normal operat- ing conditions or anticipated abnormal occurrences and the tank is orientated in such a manner that the rupture discs do not become a missile hazard to safety-related equipment. V. IMPLEMENTATION The following is intended to provide guidance to applicants and licensees regarding the 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 on its evaluation of conformance with Commission regulations. Implementation schedules for conformance to parts of the method discussed herein are contained in the referenced regulatory guide. VI.
