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 approximation of a heavy gaseous moderator is used as an illustrative example for the discussion of calculational methods in the thermal and epithermal energy regions. The energy distribution and migration area of neutrons in a infinite homogeneous medium are calculated numerically for 1/ν absorption. Semianalytic expressions are obtained for the case of weak absorption. Finally, an expression for the slowing-down density is given and its significance for the modification of age-diffusion theory to include the thermal motion of the moderator is discussed.
