Content:
ation of the post-accident inerting system, if installed. The containment must be designed to withstand this additional pressure to ensure that its integrity is maintained, thus precluding the release of radioactivity to the environment. 7. 10 CFR 50, §50.34(f)(3)(v)(B)(1) requires that the containment be designed to withstand inadvertent actuation of the post-accident inerting system, if installed. 10 CFR 50.34(f) promulgates hydrogen control requirements which include the option of a post-accident inerting system. A post-accident inerting system floods containment with an inert gas, such as carbon dioxide, during a hydrogen releasing accident. If inadvertently actuated during normal operation, containment could potentially be pressurized by the inerting system. The containment must be designed to withstand this potential inadvertent pressurization to ensure that its integrity is maintained, thus precluding the release of radioactivity to the environment. III. REVIEW PROCEDURES The following procedures are for the review of PWR dry containments. The reviewer selects and emphasizes material from these procedures as may be appropriate for a particular case. Portions of the review may be carried out on a generic basis for aspects of functional design common to a class of dry containments or by adopting the results of previous reviews of plants with essentially the same containment functional design. Upon request from the primary reviewer, the coordinated review branches will provide input for the areas of review stated in subsection I of this SRP section. The primary reviewer obtains and uses such input as required to assure that this review procedure is complete. 24 The SCSB reviews the containment response analyses to determine the acceptability of the calculated containment design pressure and temperature, and in addition, the containment depressurization time. The PERBAEB must be notified if the containment depressurization 25 time does not meet the acceptance
