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.

For decades, nuclear energy has played a role, sometimes minor and sometimes major, in humanity's exploration and research of outer space. Many space experts, scientists, astronauts, and researchers believe that nuclear energy can fundamentally change how we live and work in extraterrestrial environments and that some missions, projects, and endeavors are nearly impossible without the involvement of nuclear technologies. As federal funding is being applied to nuclear projects for various space-based applications and opportunities, an expert panel will discuss how nuclear companies and researchers are poised to capitalize.
