Blades-in turbine inspections at Quad Cities set new benchmark for Constellation
When Constellation decided to install replacement Alstom low-pressure turbines at three of its boiling water reactor plants more than 15 years ago, one benefit was knowing the new turbines should operate reliably—and without major inspections—for several years.

The Versatile Test Reactor (VTR) that is being designed today is heavily reliant upon the Argonne Reactor Codes (ARC) modeling software for predicting the operational performance of the VTR. Given its usage in the VTR, a set of validation cases appropriate for the VTR must be assembled. The measurements taken in ZPPR-15, Experimental Breeder Reactor II (EBR-II), and Fast Flux Test Facility were chosen and analyzed with the ARC software as part of creating the necessary validation basis. The results of the ARC software on the measured data are discussed here, and they demonstrate the accuracy of the ARC software on fast spectrum reactors.
