On February 17, 2016, William Ostendorff announced that he would not seek another term at the U.S. Nuclear Regulatory Commission (NRC) after his term expires on June 30, 2016. Commissioner Ostendorff, who will have served for six years in the five-member body that oversees the safety of the country’s nuclear power plants, will instead return to the United States Naval Academy to teach, according to an agency spokesman.

The departure of Commissioner Ostendorff, a former naval officer who commanded an attack submarine and later taught and led the Math and Science Division at the Naval Academy, will leave the NRC with three members—two short of its intended staffing.

Ostendorff, a Republican, was originally appointed to the Commission by President Obama in 2010 to finish the term of retiring Commissioner Dale Klein. He was sworn in to a second term on July 7, 2011. He has served at the NRC through numerous challenges including, among other things, the agency’s response to the Fukushima D’aiichi nuclear disaster in Japan in 2011. “We made a conscious decision by a unanimous commission vote, five to zero, to not require any U.S. nuclear power plant to shut down because of safety concerns,” Ostendorff told Senators last year about the Fukushima response. “We did not have those safety concerns.”

At a recent conference on nuclear energy, Ostendoff was quoted as saying, “I feel very comfortable leaving the Commission at the end of June with where we are on Fukushima.”  In a statement, NRC Chair Stephen Burns said that Commissioner Ostendorff “brought a wealth of experience to the Commission and helped guide the agency through the challenges of Fukushima, a changing industry environment and many other challenging issues.”
