Content:
that this criterion applies to designs employing containment structures. The term “ferritic” was removed to avoid limiting the scope of the criterion to ferritic materials. With this revision, the staff believes that this criterion is more broadly applicable to all non-LWR designs. The word “pressure” was left in the title to reflect that, while a design might not have a high-pressure containment like a traditional LWR, the containment still serves a pressure-retaining function. 52 Capability for containment leakage rate testing. Same as ARDC The reactor containment structure and other equipment that may be subjected to containment test conditions shall be SFR-DC 51–57 support SFR-DC 50, which specifically applies to non-LWR designs that use a fixed containment structure. Therefore, the word “structure” is added to each of these SFR-DC APPENDIX B. SODIUM-COOLED FAST REACTOR DESIGN CRITERIA Appendix B to DG-1330, Page B-24 V. Reactor Containment Criterion SFR-DC Title and Content NRC Rationale for Adaption to GDC designed so that periodic integrated leakage rate testing can be conducted at containment design pressure. to clearly convey the understanding that this criterion applies to designs employing containment structures. 53 Provisions for containment testing and inspection. Same as ARDC The reactor containment structure shall be designed to permit (1) appropriate periodic inspection of all important areas, such as penetrations, (2) an appropriate surveillance program, and (3) periodic testing at containment design pressure of the leak- tightness of penetrations that have resilient seals and expansion bellows. SFR-DC 51–57 support SFR-DC 50, which specifically applies to non-LWR designs that use a fixed containment structure. Therefore, the word “structure” is added to each of these SFR-DC to clearly convey the understanding that this criterion only applies to designs employing containment structures. 54 Piping systems penetrating containment.
