2. Influence of erosion-corrosion on plant operation and potentially affected components

2.1 Influence of corrosion erosion

Corrosion-erosion can lead to significant thinning of the most sensitive components in the most affected areas, and this can result in the risk of fluid pressure no longer being controlled if the residual thickness is less than the minimum thickness required to withstand pressure loading, or even additional loads.

In certain situations, this has led to dramatic accidents , some of which are detailed below. This type of accident is not exclusive to the nuclear industry (as in the case of the Iatan-...
