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.

The boost and damping of the level of potential fluctuations are reproduced in imitation experiments with an electron beam driven discharge in the linear open system. The most pronounced instability of the sheath potential drop is observed in hydrogen plasmas in the presence of small admixtures of oxygen for materials which form oxides with enhanced emissivity of secondary electrons. Measurements of the plasma fluctuations level are in a qualitative agreement with analytical analysis of temporal evolution of plasma -surface interaction as function of internal and external electric circuit parameters.
The surface currents which appear between zones with different emissivity and are closed by the bulk of the incident plasma flow have been studied with the use of the two-plate collector. It is shown that these currents can crucially influence the plasma turbulence.
