TENNESSEE NUCLEAR WEAPONS FACILITY CONTINUES TO BE PLAGUED BY SAFETY PROBLEMS
SAFETY BOARD: OAK RIDGE NUCLEAR STORAGE FACILITY UNSAFE
NNSA AND CONTRACTOR CONSPIRE TO DOCTOR SAFETY RECORDS
The safest building at the Y-12 National Security Complex in Oak Ridge, Tennessee, is not safe enough. That is the conclusion of the Defense Nuclear Facilities Safety Board in an April 21, 2020, Staff Report on the storage of reactive materials at the Highly Enriched Uranium Materials Facility (HEUMF). The Staff Report was released on June 1, 2020, accompanied by a letter from Safety Board Chair Bruce Hamilton to Dan Brouillette, Secretary of Energy.
Faced with three separate discoveries of highly enriched uranium that posed an undetermined safety risk because it was pyrophoric, the contractor at Y-12, Consolidated Nuclear Services, without characterizing the materials, decided to re-categorize all the materials as not pyrophoric. NNSA agreed and took the additional step of ordering the contractor to revise the Documented Safety Analysis for the HEUMF to incorporate the material types into the facility safety basis. Neither action was justified, according to the Safety Board, and neither was sufficient to assure worker safety.
