Because of the high RCS pressure throughout the entire process of degradation, HPME occurs.
In addition, the RCS maintains a low-pressure condition to prevent HPME. Only MCCI contributes to the later pressurization of the containment.
Meanwhile, although the HPME increases the amount of steam in the containment, thereby accelerating overpressure, the hydrogen is also maintained in an inert atmosphere, which prevents combustion.
As the analysis above indicates, intentional depressurization has the positive effect of preventing HPME and delaying RPV failure.
HPME is avoided by intentional depressurization, but the RPV still inevitably fails after exhausting all ACCs.
