Keeping up with Kewaunee
In October 2012, Dominion Energy announced it was closing the Kewaunee nuclear power plant, a two-loop 574-MWe pressurized water reactor located about 27 miles southeast of Green Bay, Wis., on the western shore of Lake Michigan. At the time, Dominion said the plant was running well, but that low wholesale electricity prices in the region made it uneconomical to continue operation of the single-unit merchant power plant.

A theoretical approximation, which bridges the gap between NR and NRIA approximations for resonance integrals, is derived, making use of the concept of escape probability in energy space for a single line. The nature of this approach is similar to Goldstein and Cohen λ method, and may be considered a physical interpretation of it, leading to simpler, nearly equal results. The method is applied to the heterogeneous case. Numerical calculations, but neglecting interference scattering, lead to simple fitting formulae for UO2 and ThO2 rods at different temperatures; the calculations are in good agreement with experiment.
