The Nuclear Regulatory Commission (NRC) receives reports about potential safety problems from plant workers, the public, members of the news media, and elected officials. The NRC calls these potential safety problems allegations, making the sources allegators. In the five years between 2012 and 2016, the NRC received 450 to 600 allegations each year. The majority of the allegations involve the nuclear power reactors licensed by the NRC.
While the allegations received by the NRC about nuclear power reactors cover a wide range of issues, nearly half involve chilled work environments where workers don’t feel free to raise concerns and discrimination by management for having raised concerns.
In 2016, the NRC received more allegations about conditions at the Watts Bar nuclear plant in Tennessee than about any other facility in America. Watts Bar’s 31 allegations exceeded the allegations from the second highest site (the Sequoyah nuclear plant, also in Tennessee, at 17) and third highest site (the Palo Verde nuclear plant in Arizona, at 12) combined. The Browns Ferry nuclear plant in Alabama and the Pilgrim nuclear plant in Massachusetts tied for fourth place with 10 allegations each. In other words, Watts Bar tops the list with a very comfortable margin.
In 2016, the NRC received double-digit numbers of allegations about five nuclear plants. Watts Bar, Sequoyah and Browns Ferry are owned and operated by the Tennessee Valley Authority (TVA). Why did three TVA nuclear plants place among the top five sources of allegations to the NRC?
Because TVA only operates three nuclear plants.
The NRC received zero allegations about ten nuclear plants during 2016. In the five year period between 2012 and 2016, the NRC only received a total of three allegations each about the Clinton nuclear plant in Illinois and the Three Mile Island Unit 1 reactor in Pennsylvania (the unit that didn’t melt down). By comparison, the NRC received 110 allegations about Watts Bar, 55 allegations about Sequoyah, and 58 allegations about Browns Ferry.
TVA President Bill Johnson told Chattanooga Time Free Press Business Editor Dave Flessner that TVA is working on its safety culture problems and “there should be no public concern about the safety of our nuclear plants.” The NRC received 30 of the 31 allegations last year from workers at Watts Bar, all 17 allegations last year from workers at Sequoyah, and all 10 allegations last year from workers at Browns Ferry.
So President Johnson is somewhat right— the public has no concerns about the safety of TVA’s nuclear plants. But when so many TVA nuclear plant workers have so many nuclear safety concerns, the public has every reason to be very, very concerned.
Nuclear plant workers are somewhat like canaries in coal mines. Each is likely to be the first to sense danger. And when nuclear canaries morph into nuclear allegators in such large numbers, that sense of ominous danger cannot be downplayed.
