Ashley Pond and LANL History


Ashley Pond - Then and Now
In March 1943, a small group of scientists came to Los Alamos for Project Y on the Manhattan Project. Their goal was to develop the world’s first nuclear weapon.
There was little thought about waste disposal or environmental contamination. The objective was to win the war and protect the United States.
The Laboratory still provides national security, which is now inseparable from protecting the environment.
LANL makes components for nuclear weapons.
LANL manufactures an average of two radioactive components or pits per year, certifies that they will work, and dismantles old pits. Current environmental decisions give LANL permission to produce up to 20 pits per year.
LANL does not make nuclear weapons.
Nuclear weapons are assembled elsewhere.
