Structural integrity assessment of different components of a power plant

This document analyzes the structural integrity of several tubes of material P91 [1], [2] and [3] used in a power plant. The appearance of three failures in different steps of the plant construction process requires a detailed an in-depth analysis to be performed in order to determine whether this will lead to the generalised failure of the rest of components or whether, on the other hand, the actions performed after the failures (post-weld heat treatment) are enough to ensure the correct operation of the plant.
