Content:
) defense in depth is not impacted by system leakage. Reference to the operation of applicable portions of the protection system, structural and equipment cooling water systems, and power transfers is considered part of the more general “associated systems” for operability testing of the system as a whole. The GDC reference to electric power was removed. Refer to SFR- DC17 concerning those systems that require electric power. 41 Containment atmosphere cleanup. Same as ARDC Systems to control fission products and other substances that may be released into the reactor containment shall be provided as necessary to reduce, consistent with the functioning of other associated systems, the concentration and quality of fission products released to the environment following postulated accidents and to control the concentration of other substances in the containment atmosphere following postulated accidents to ensure that containment integrity is maintained. Advanced reactors offer potential for reaction product generation that is different from that associated with clad metal-water interactions. Therefore, the terms “hydrogen” and “oxygen” are removed while “other substances” is retained to allow for exceptions. The GDC reference to electric power was removed. Refer to SFR- DC17 concerning those systems that require electric power. APPENDIX B. SODIUM-COOLED FAST REACTOR DESIGN CRITERIA Appendix B to DG-1330, Page B-21 IV. Fluid Systems Criterion SFR-DC Title and Content NRC Rationale for Adaption to GDC Each system shall have suitable redundancy in components and features and suitable interconnections, leak detection, isolation, and containment capabilities to ensure that its safety function can be accomplished, assuming a single failure. 42 Inspection of containment atmosphere cleanup systems. Same as GDC 43 Testing of containment atmosphere cleanup systems. Same as ARDC The containment atmosphere cleanup systems shall be designed to permit appropriate
