Effect of Elevated Temperature and Internal Pressure due to Severe Accidents on the Internal Pressure Capacity of Prestressed Concrete Containment Vessel

Table 5

Variation of internal pressures due to material uncertainty under SBO (MPa).

Limit states	Uncertainty	Pressure only	SBO
Onset of leakage	Lower level	0.975	0.1095
	Upper level		0.110
Functional failure	Lower level	1.287	0.117
	Upper level		0.120
