The NRC and Nuclear Safety Culture: Do As I Say, Not As I Do

, director, Nuclear Safety Project

Many times over the past 20 years the Nuclear Regulatory Commission (NRC) has intervened when evidence strongly suggested a nuclear power plant had nuclear safety culture problems. The evidence used by the NRC to trigger its interventions was readily available to the plant owners, but the owners had downplayed or rationalized away the evidence until the NRC forced them to face reality.

The evidence used by the NRC to detect these nuclear safety culture problems included work force surveys indicating a sizeable portion of workers reluctant to raise safety concerns and allegations received by NRC from workers about reprisals and harassment they experienced after raising safety concerns.

Ample evidence strongly suggests that the NRC itself has nuclear safety culture problems. The NRC’s Office of the Inspector General (OIG) has surveyed the safety culture and climate within the NRC every three years for the past two decades. The latest survey was conducted during 2015 and released in March 2016. Figure 1 from the OIG’s 2015 survey along with data from the annual Federal Employee Viewpoint Surveys and other sources show safety culture problems as bad as—it not considerably worse—than the worst safety culture problems identified at Millstone, Davis-Besse, and yes, even the TVA reactors.

Kudos to NRC for Lessons-Learned Review at Columbia Fuel Fabrication Facility

Disaster by Design/Safety by Intent #63

Safety by Intent

Westinghouse Electric Corporation notified the Nuclear Regulatory Commission (NRC) on July 14, 2016, that workers at its Columbia Fuel Fabrication Facility (CFFF) in South Carolina found significant accumulation of uranium in a ventilation system. The amount of enriched uranium exceeded limits established at the facility as protection against inadvertent criticality.

Nuclear Safety Performance at Pilgrim

, director, Nuclear Safety Project

The Nuclear Regulatory Commission (NRC) held a public meeting on Tuesday, January 31, 2017, in Plymouth, Massachusetts. A large crowd of over 300 individuals (perhaps thousands more by White House math) attended, including me. Elected officials in Massachusetts—the attorney general, the governor, the entire US Congressional delegation, and state senators and representatives—had requested the meeting. Many of these officials, or their representatives, attended the meeting.

The elected officials asked the NRC to conduct a public meeting to discuss the contents of an email from the leader of an NRC inspection team at Pilgrim to others within the agency regarding the results from the first week’s efforts. An NRC staffer forwarded this email to others within the agency, and inadvertently to Diane Turco of the Cape Downwinders, a local organization. The contents of the leaked email generated considerable attention.

Nuclear Regulatory Crusader

To many, the acronym NRC stands for Nuclear Regulatory Commission. At times, NRC has been said to stand for Nobody Really Cares, Nuclear Rubberstamp Committee, and Nielsen Ratings Commission.

In regard to Larry Criscione, it may stand for Nuclear Regulatory Crusader. Read more >

Not-so-Fabulous Five

, director, Nuclear Safety Project

To some, “Fabulous Five “ brings back memories of the 1991 recruits for the University of Michigan’s basketball team—Chris Webber, Jalen Rose, Juwan Howard, Jimmy King, and Ray Jackson. The five powered Michigan to the NCAA Division I championship games in 1992 and 1993.

Others may recall the “Fab Five,” a made-for-TV movie about a 2006 cheerleader scandal at a high school in Texas.

No one hearing “Fabulous Five” thinks about the performance of the nuclear reactors owned and operated by Entergy between 2011 and 2015. The performance during those five years was anything but fabulous, unless fabulously bad counts. Read more >
