nonnuclear safety and Quality Group D (see Regulatory Guide 1.26) requirements because the system is not necessary for safe shutdown, accident prevention, or accident mitigation. 1. The applicant’s design meets the requirements of GDC 4 as it relates to protection against the effects of earthquakes through conformance with Positions C.2 and C.3 of Regulatory Guide 1.29. Position C.2 indicates that the failure of nonsafety-related systems should not have an adverse effects on safety-related systems. Position C.3 indicates that seismic Category 1 design requirements should extend 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 GDC 4 as it relates to the protection of safety-related equipment from adverse environmental effects and from missiles generated by rupture disc failure. This criterion is met because the system design prevents steam or water release to containment under any normal operating conditions or anticipated abnormal occurrences and because the tank is orientated such that the rupture discs do not pose a missile hazard to safety-related equipment. For DC and COL reviews, the findings will also summarize the staff’s evaluation of requirements and restrictions (e.g., interface requirements and site parameters) and COL action items relevant to this SRP section. In addition, to the extent that the review is not discussed in other SER sections, the findings will summarize the staff's evaluation of the ITAAC, including design acceptance criteria, as applicable. 5.4.11-8 Revision 3 - March 2007 V. IMPLEMENTATION The staff will use this SRP section in performing safety evaluations of DC applications and license applications submitted by applicants pursuant to 10 CFR Part 50 or 10 CFR Part 52. Except when the applicant proposes an acceptable alternative method for complying with specified portions of the
