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

<table>Structure mechanic assessment for a typical integration point in the surge line (eg: strain at uniform elongation concerning the respective temperature, eg/TF: strain at uniform elongation divided by stress triaxiality factor, ep: calculated accumulated plastic strain).</table>
