A federal contractor violated nuclear safety requirements at the Y-12 National Security Complex, according to the National Nuclear Security Administration.

The violations are associated with the accumulations of uranium-235 in a glovebox, furnace, and casting line in Building 9212 at Y-12. The equipment is used to recover and process uranium-235, a fissile material that can be used in nuclear weapons and reactors.

A federal contractor violated nuclear safety requirements at the Y-12 National Security Complex, according to the National Nuclear Security Administration.

The violations are associated with the accumulations of uranium-235 in a glovebox, furnace, and casting line in Building 9212 at Y-12. The equipment is used to recover and process uranium-235, a fissile material that can be used in nuclear weapons and reactors.

The buildup of enriched uranium, discovered after hydraulic lines leaked in a glovebox, exceeded limits established by a safety program meant to help prevent a nuclear chain reaction.

An investigation of the uranium accumulations found weaknesses in five areas, according to the NNSA, which is part of the U.S. Department of Energy and overseas nuclear weapons work at sites like Y-12. Among the deficiencies were procedural compliances, evaluations of process changes, the analyses of causes, the establishment of roles and responsibilities, and the implementation of a program meant to prevent inadvertent accumulations.

“The National Nuclear Security Administration considers these deficiencies to be of high safety significance,” Administrator Lisa Gordon-Hagerty wrote in an April 6 letter. “Although there were no actual consequences to the public, workers, or the environment, these deficiencies eroded the barriers preventing a nuclear criticality and could, if left uncorrected, adversely impact nuclear and worker safety at the Y-12 National Security Complex.”

The letter was sent to Morgan Smith, president and chief executive officer of Consolidated Nuclear Security. CNS manages and operates Y-12, as well as the Pantex Plant near Amarillo, Texas, for the NNSA.

President Barack Obama on Tuesday nominated Elizabeth Sherwood-Randall, a presidential aide and national security official, to become deputy secretary of the U.S. Department of Energy. If confirmed by the U.S. Senate, she would replace Daniel Poneman, who is stepping down from the No. 2 job this fall after five years. Sherwood-Randall currently serves as special assistant to the president and White House coordinator for defense policy, countering weapons of mass destruction, and arms control, a position she has held since 2013. She served as special assistant to the president and senior director for European affairs at the National Security Council from 2009 to 2013. The New York Times reported that Sherwood-Randall, 54, would bring a background in nuclear weapons and nonproliferation strategy to the department, which has split responsibilities for energy strategy and the country’s weapons and counter-proliferation work. It would be her third job in the Obama administration.

The newspaper said Sherwood-Randall oversaw the effort to get chemical weapons out of Syria and the development of the administration’s policy for dealing with the nuclear arsenal. Poneman has been U.S. deputy secretary of energy since May 2009, and he also served as chief operating officer under former Energy Secretary Steven Chu. Poneman has been focused on nuclear safety and proliferation, among other issues, the Times said. He briefly served as acting secretary in 2013 before the confirmation of Energy Secretary Ernest Moniz.
