Content:
e 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. 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. Considering that a passive containment cooling system may be used or that the containment may have an additional safety function other than radionuclide retention, additional wording for maintaining safety-functions is added. The GDC reference to electric power was removed. Refer to ARDC 17 concerning those systems that require electric power. 42 Inspection of containment atmosphere cleanup systems. Same as GDC 43 Testing of containment atmosphere cleanup systems. The containment atmosphere cleanup systems shall be designed to permit appropriate periodic functional testing to ensure (1) the structural and leaktight integrity of its components, (2) the operability and performance of the system components, 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 sequence that brings the systems into operation, including the operation of associated systems. “Active” has been deleted in item (2), as appropriate operability and performance testing of system components is required regardless of an active or passive nature, as are cited examples of active system components. Examples of active systems under item (2) have been deleted, both to conform to similar wording in ARDC 37 and 40 and ensure that passive as well as active system components are considered.
