Safety Analysis Flaws Plague Los Alamos TRU Waste Handing Facility
The Defense Nuclear Facilities Safety Board (DNFSB) believes that the Radioassay and Nondestructive Testing (RANT) Shipping Facility at Los Alamos National Laboratory must resolve safety issues prior to resuming operations. The DNFSB staff review team identified “significant flaws” in hazard and accident analyses.
The RANT Shipping Facility is used to load transuranic (TRU) waste, typically either waste drums or standard waste boxes, into TRUPACT shipping containers. This facility supports the LANL TRU program and will be used long-term. The RANT Shipping Facility is currently in standby with no TRU waste present, pending the resumption of TRU waste shipments.
In November 2013, the contractor, LANS, submitted a new safety analysis, called a Documented Safety Analysis (DSA), to DOE oversight officials at the Los Alamos Field Office (LAFO) for approval. In February 2014, WIPP was shut down due to a radiation leak in the underground. It is believed that wheat-based kitty litter was mixed with nitrate salts in a transuranic waste drum as it was processed at Los Alamos that potentially caused the reaction that breached the container. In July 2014, LAFO completed its review of the RANT DSA and noted only four actions needed.
The DNFSB staff reviewed the DSA and identified significant weaknesses in the hazard analysis (HA), accident analysis, and safety controls. The review revealed inadequate identification and implementation of safety controls to protect the public and workers.
The DNFSB report found that LANS and LAFO underestimated consequences from potential crane failure accidents, seismic events, and fires. Underestimating possible consequences like these can lead to increased radiologic releases to the environment.
