Researchers at Argonne National Laboratory have developed a multiphysics simulation modeling tool to predict how feedwater heater (FWH) tubes in a nuclear power plant break down over time. The model, which has the potential to improve maintenance schedules and save operating costs at nuclear facilities, is described in a paper titled “Numerical Analysis with Experimental Validation of Tube Fatigue Failure in Feedwater Heaters,” published in a recent issue of Engineering Failure Analysis.

Advanced nuclear technology firm TerraPower announced today the selection of four suppliers to support its Natrium reactor demonstration project, in development near a retiring coal plant in Kemmerer, Wyo.
