TA-21 Closure ProjectTA-21 UpdateD&D: Workers at Building 21-155, Tritium Systems Test Assembly (TSTA), are removing contaminated systems and components. They will be performing asbestos and hazardous materials abatement, in order to prepare the building for demolition. MDA B: Commencing mobilization to perform direct push sampling of waste cells. We are also in the design process and procurement of our long lead time procurement items, (enclosures, ventilation, and support systems). DP Aggregate: Completing Nature and Extent field sampling activities and conducting cleanup of a PCB contaminated site. TA-21, also known as the Delta Prime (DP) Site, is on DP Mesa, situated immediately east-southeast of the Los Alamos town site at an elevation of 7140 feet. TA-21 was the site of chemical research for refining plutonium and plutonium metal production from 1945 to 1978. As a result, most waste disposal activities involved plutonium. MDAs located at TA-21 include MDAs A, B, T, U and V. These MDAs are listed as solid waste management units (SWMUs) in LANL’s Hazardous Waste Facility Permit. TA-21 Decontamination & DecommissioningDelta Prime WestThe Reconnaissance Level Characterization from the TA-21 D&D investigative effort of Delta Prime (DP) West has been completed. Delta Prime East & the Central CorridorThe Reconnaissance Level Characterization for the TA-21 D&D investigative effort of DP East and the central corridor buildings will provide an initial assessment of the contamination, hazards, and other conditions associated with the subject facilities. Such an assessment will enable project personnel to perform the following tasks:
