Failure Assessment Methodologies for Pressure-Retaining Components under Severe Accident Loading

Table 1

Failure assessment criteria.

Run #	Creep failure assessment	Plastic failure assessment
A	60% limit curve (see Figure 5) with variable TF	Uniform elongation/variable TF
B	100% limit curve (see Figure 5) with constant TF = 1	Uniform elongation/constant TF
