WASHINGTON, D.C. – Continuing its efforts to reduce the size
of the U.S. nuclear weapons stockpile, the Department of
Energy’s National Nuclear Security Administration (NNSA)
announced that uranium components from two major nuclear weapons
systems formerly deployed on U.S. Air Force missiles and aircraft
have been dismantled at the Y-12 National Security Complex in Oak
Ridge, TN.
Y-12 workers successfully dismantled the last remaining piece of
the W56, a nuclear warhead associated with the Minuteman II
Intercontinental Ballistic Missile, and also completed the
dismantling of two modifications of the B61, a strategic nuclear
bomb.
The dismantlement process includes four steps: retiring a weapon
from active or inactive service; returning and storing it; taking
it apart by physically separating the high explosives from the
special nuclear material; and processing the resulting material and
components, which includes demilitarization, reuse,
declassification, recycling, and ultimate disposal.
