Deformation Analysis Of A 900 MW Reactor Pressure Vessel Head By Comparison Of Holographic Interferograms And Computer Generated Interferograms

During pressure build-up in a 900 MW reactor pressure vessel, the head of the vessel was holographed. It will be shown how a maximum of information can be extracted from the hologram using computer generated interferograms. Based on a trial and error method the deformation assumption for the head is altered until a best correlation is reached between computer generation and experiment.
