propriate periodic inspection of important components, such as heat exchangers and piping, to ensure the integrity and capability of the systems. This renamed ARDC accounts for advanced reactor system design differences to include possible cooling requirements for SSCs important to safety. 46 Testing of structural and equipment cooling systems. The structural and equipment cooling systems shall be designed to permit appropriate periodic functional testing to ensure (1) the structural and leaktight integrity of their components, (2) the operability and performance of the system components, This renamed ARDC accounts for advanced reactor system design differences to include possible cooling requirements for SSCs important to safety. Specific mention of “pressure” testing has been removed yet remains a potential requirement should it be necessary as a component of “…appropriate periodic functional APPENDIX A. ADVANCED REACTOR DESIGN CRITERIA Appendix A to DG-1330, Page A-20 IV. Fluid Systems Criterion ARDC Title and Content NRC Rationale for Adaptions to GDC and (3) the operability of the systems as a whole and, under conditions as close to design as practical, the performance of the full operational sequences that bring the systems into operation for reactor shutdown and postulated accidents, including the operation of associated systems. testing...” of cooling systems. A non-leaktight system may be acceptable for some designs provided that (1) the system leakage does not impact safety functions under all conditions, and (2) defense in depth is not impacted by system leakage. “Active” has been deleted in item (2) because appropriate operability and performance tests of system components are required regardless of their active or passive nature. The LOCA reference has been removed to provide for any postulated accident that might affect subject SSCs. The GDC reference to electric power was removed. Refer to ARDC 17 concerning those systems that require
