### Inelastic Analysis Results and Assessment  
The maximum principal plastic strain values on the BB cap region structural components from the inelastic simulation results are plotted in Figure 10. The pattern of the stress contour is similar to the linear analysis. It can be also seen that some locations in the _first wall_ and _breader pins_ are under relatively high plastic strain. Assessment following the inelastic criteria in Section 2.5 is performed for the IPFL and ILFED damage modes and the results are presented in Table 2. Similar to the elastic assessment, safety margins for IPFL criteria are estimated by comparing the linearized strain values with the corresponding strain limit. In order to estimate the ILFED safety margin, the local strain values are multiplied by the corresponding stress triaxiality factor--TF, and then compared with the uniaxial strain limits. The distribution of the TF contour is plotted in Figure 11. Due to the \begin{table}
