41.4 Hydrogen Generation and Mixing

The MAAP4.04 code, (Reference 41-8) was used to investigate the hydrogen generation rate in the core and releases from the reactor coolant system into the containment for the AP600 hydrogen analysis (Reference 41-2). The accident progression and containment response such as break location, sequence timing and rate of containment flooding can have a significant effect on hydrogen generation. The overall sequence behavior for the AP1000 is essentially the same as the AP600. The AP1000 MAAP4 04 analysis results for dominant accident classes are provided in Attachment 41A. refre the-resutts-and4nsight-s-for-eac-h-accident-c-ass-fom-the-AP-6O0qydrogen analytses-ar e-ppticable-to-the-P-I•OOO-A.

discussion of the insights for each accident class is provided
