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 transport equation which describes the thermal neutron population in and around a neutron detector is converted to an iterative integral equation. This integral equation is then solved for a wide range of specific cases using a digital computer. Using this method of calculation, the effects upon neutron density of nonisotropic scatter in the surrounding medium, of finite detector dimensions and of scatter by the detector are calculated to an accuracy of better than 1%. Detailed maps of the scalar neutron density in and around finite detectors are available from the calculations. The problem of nonisotropic, non-uniform initial neutron density is formulated using the integral method.
