This presentation defines high temperature hydrogen attack (HTHA) and discusses its causes, volumetric HTHA caused by growing voids, how to avoid HTHA by utilizing the Nelson curves, and how to get ahead of the curve. An MPC review of Nelson curve data and information on how to predict remaining life with volumetric and crack-like assessments are also included.
