Constellation, formerly Exelon Generation, owner and operator of the nation’s largest nuclear reactor fleet, announced this morning the completion of its separation from Exelon Corporation and its launch as a stand-alone, publicly traded company. Headquartered in Baltimore, Md., the new company began trading today on the Nasdaq Global Select Market under the symbol “CEG.”

Exelon announced last February that it had begun the effort to separate its utility businesses from its competitive power generation and customer-facing energy businesses.

Throughout the history of commercial nuclear power plant operations, there have been events that changed the industry. The incidents at Three Mile Island and Fukushima brought about great advancements in how nuclear plants are operated, including additional safety measures and supplemental training on how to prevent such events. Looking forward, the commercial nuclear industry is poised for a similar transformative change: one motivated by financial viability.

In September, cable television’s Science Channel aired an episode on power plant catastrophes as part of its series Deadly Engineering, with one principal segment on the 1979 Three Mile Island accident. The episode contains several inaccuracies and distortions—perhaps the biggest mistake being that the TMI accident was featured in Deadly Engineering at all, since no deaths or long-term adverse health trends resulted from the accident.

Leaving that aside, the episode includes other errors that executives at Science Channel should have caught and corrected before airing. They also should have made sure to include knowledgeable scientific reviewers from both sides of the nuclear issue, which they did not.

The biggest falsehood in the episode comes very near the beginning, with the horribly erroneous claim that most of eastern Pennsylvania was made permanently uninhabitable by the accident. Incredibly wrong, and likely believable and very frightening to some viewers.

The Bulletin of the Atomic Scientists (BAS) is currently featuring on its website a series of five articles by young American and Russian scholars on nuclear safety, with a focus on the industry’s three major accidents: Three Mile Island, Chernobyl, and Fukushima.

In one of those articles, “Don’t let nuclear accidents scare you away from nuclear power,” the authors conclude that “even after accounting for both the immediate and long-term toll of the three accidents, nuclear power has a remarkably safe track record compared to coal, natural gas, and even hydroelectric power.”
