The document discusses the history of nuclear weapons development, arms reduction treaties between countries to limit stockpiles, and processes for dismantling nuclear weapons. It notes that the first nuclear weapons were created in the 1940s by the Manhattan Project led by Robert Oppenheimer. Later treaties like START and New START aimed to further reduce warheads and call for dismantlement. The dismantlement process involves removing the physics package, high explosives, and breaking down the core for other uses. The main reason given for disarmament is to prevent weapons from falling into the hands of terrorist or unstable groups.
2. History of the Nuclear Weapon
• The first nuclear weapons were produced in
the 1940’s by the Manhattan Project under
the direction of Robert Oppenheimer.
• The Manhattan Project created three bombs

Trinity Fat ManLittle Boy
3. History Cont’d
• Eventually the bombs became bigger and
bigger, as the sizes got bigger the explosions
also became bigger.
Trinity Test, 1945 Tsar Bomba, 1961
4. Reduction Treaties
• With the buildup of weapons also came the
talk of reducing the stockpiles.
START I
The 1st of the Strategic Arms
Reduction Treaties was signed by
the United States and the Soviet
Union in July, 1991.
This limited the number of
active warheads in the
arsenals.
New START
The newest of the Strategic Arms
Reduction Treaties was signed between
Russia and the U.S. In April, 2010
This calls for further limiting of
warheads, and calls for the
dismantlement of the stockpiled
warheads
5. Dismantlement Practices
• The weapon’s physics package is removed,
then the high explosives surrounding the core,
and finally the core is broken down for other
uses.
1: Nuclear weapon transported to
disarmament facility
2: Weapon is hauled by crane into storeroom
and dismantled
3: Physics package is removed and placed in
separate container
4: Inspectors use device to confirm
radioactive material is present in container
5: Container is then sealed in a side-room
overnight with CCTV
6: Next day physics package is transported to
a hot cell for dismantling
7: Radioactive material is removed safely and
put into storage
6. What's Next for the Nuclear Material
• The core of the bomb is broken down for use
in nuclear reactor rods.
7. Why the Need for Disarmament
• The main reason for nuclear disarmament is
so that a weapon can not fall into the hands of
a terrorist group or another unstable group
such as a third world power hungry dictator.
