In a surprise -- and, most likely welcome -- announcement on Tuesday, the timeline to decommission the Oyster Creek Nuclear Generating Station just shrunk. By at least five decades. Shutting down outdated U.S. nuclear electricity plants is usually a long-term affair because of the harmful radiation that persists. About a month ago, Oyster Creek's owners submitted a closure plan for the nation's oldest active commercial nuke plant taking an estimated 60 years. The lengthy term prompted eye-rolls from the environmental community. Now, Osyter Creek's owner, Exelon, says it has a deal to shut down the 779-acre site properly in just eight years. It hinges on an agreement for Exelon to sell the entire property to Holtec International, a South Jersey-based engineering and energy-equipment company.
