  • Lab starts demo work at TA-54

    Los Alamos National Laboratory recently began to demolish Dome 281 — a 4,100-square- foot metal and fabric dome at the lab’s Technical Area 54.  It’s the next step in LANL’s multi-year closure plan for TA-54, which must be complete by 2015 under the Consent Order cleanup agreement with the state of New Mexico.  Removing the domes at TA-54 is also important to the San Ildefonso Pueblo, whose sacred lands are just to the north of TA-54.

  • Pipe with excess plutonium halts lab clean-up

    Discovery of a pipe with a high level of plutonium-239 at a clean-up site at Los Alamos National Laboratory has forced officials to shut down operations.
    The pipe, which was dug up by an excavator three weeks ago, had plutonium-239 that exceeded the amount lab officials had expected and that was allowed above the ground, lab spokesman Fred deSousa said Friday. The lab had estimated about 200 grams of plutonium-239 over the 6-acre clean-up site. The pipe alone had 42 grams, or about 1.6 ounces.
