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.

For members: DOE investigating fuel element performance after elevated radiation found at HFIR

The U.S. Department of Energy is investigating fuel element performance in the High Flux Isotope Reactor, which is used for research and isotope production at Oak Ridge National Laboratory, after elevated radiation levels were found in the cooling system last year, possibly due to a pinhole leak.

The investigation of potential noncompliances with DOE nuclear safety program requirements was announced this month by the DOE Office of Enterprise Assessments’ Office of Enforcement. The office notified UT-Battelle LLC, ORNL’s managing and operating contractor, and BWXT Nuclear Operations Group Inc. of Lynchburg, Virginia, on December 5. BWXT manufactured components that were involved.

ORNL has said the slightly elevated reading in the primary cooling system was well below alarm levels, and there was no impact to the public, the environment, or workers, and the reactor was not damaged or compromised.

Y-12 criticality alarms function properly in tests

  Alarms designed to detect a nuclear criticality accident at the Y-12 National Security Complex have been tested, and the systems functioned appropriately and as required, the plant said in November. Y-12 has had a criticality accident alarm system since 1945. A criticality accident would occur if there were an uncontrolled nuclear chain reaction. It could result in the release of radiation and significant exposures to nearby workers if the area were not immediately evacuated. It’s something that the plant takes steps to avoid. The alarms are designed to alert workers if there is an accident. A nuclear criticality alarm at the 811-acre plant, which works on nuclear weapons components and stores highly enriched uranium, has been given credit for helping to save lives in a nuclear criticality accident in 1958. In that case, which was the first process criticality accident in the United States, Y-12 employees immediately evacuated when they heard the alarm. A report published by Consolidated Nuclear Security, a federal contractor, said the basic design and electronic configuration of the older criticality alarm system installed in Y-12’s existing facilities, with the exception of the Highly Enriched Uranium Materials Facility, date back to 1957. The legacy system has received many upgrades since installation, and detector stations have been removed and relocated as enriched uranium operations have evolved, said the report, titled “Qualification of Y-12 Legacy Criticality Accident Alarm System Detectors.” [Read more…]

UT-Battelle has to take corrective action, pay $120,000 after unauthorized disclosure of classified information

UT-Battelle, which manages and operates Oak Ridge National Laboratory, has to take corrective actions and pay $120,000 for the unauthorized disclosure of classified information and the introduction of classified information into unapproved information systems at the lab, according to a settlement agreement with the U.S. Department of Energy that was approved in August.

The settlement agreement was for a security event discovered March 28, 2016. On that date, UT-Battelle discovered that presentations containing classified information had been processed on unapproved information systems during a roughly five-year period. The classified presentations were stored on unapproved servers, information systems, and removable electronic media, and transmitted by unauthorized means, according to the DOE Office of Enterprise Assessments’ Office of Enforcement.

In addition, classified information was visually presented to uncleared students on a specific program, including three foreign nationals from non-sensitive countries, DOE said.

The highest classification level and category of information contained in the presentations is Secret/Restricted Data, including No Foreign, said Steven C. Simonson, director of the Office of Enforcement. [Read more…]
