The early summits concentrated on securing the "direct use" fissile materials
, HEU and separated plutonium, which terrorists or rogue states could employ to make nuclear weapons.
Department of Energy, in a (http://nnsa.energy.gov/mediaroom/pressreleases/japannss) statement released at the time, said the move was aimed at preventing "unauthorized actors, criminals, or terrorists" from acquiring fissile materials
Unmaking the Bomb is a book by renowned experts that ably summarizes the current situation with respect to fissile materials
and suggests practical steps to "unmaking" the bomb and ensuring that it stays unmade.
"Iran's program would then have to be reconfigured to make weapons-grade fissile material
, which would have to be converted to metal, be molded into the shape required for a bomb and undergo countless other complex weaponization processes.
There is already a proposed international treaty to prohibit the production of fissile material
for weapons purposes, the Fissile Material
Cut-off Treaty, but it is yet to be negotiated.
We also recognize that the Fissile Material
Cut off Treaty (FMCT) is a means to addressing the proliferation of fissile material
which amounts to nuclear weapon proliferation, and that it is imperative to begin negotiations at the Conference on Disarmament on a non-discriminatory, multilateral and effectively verifiable treaty that bans the production of fissile material
for manufacturing of nuclear weapons and other nuclear explosive devices.
The Fissile Material
Cut-off Treaty (FMCT) has remained a captivating subject for the nuclear abolitionists during the recent years.
What if the agenda changes from FMCT to FMRT (Fissile Material
"For this reason, I have determined that it is necessary to continue the national emergency declared with respect to the risk of nuclear proliferation created by the accumulation of a large volume of weapons-usable fissile material
in the territory of the Russian Federation and maintain in force these emergency authorities to respond to this threat, concluded Obama in the letter.
Rather, India's nuclear posture and decisions to join arms control treaties, such as the CTBT and a fissile material
cutoff treaty, will be influenced most by developments in the nuclear programs of its regional competitors, Pakistan and China.
3 -- Pakistan may already have not just more nuclear warheads than India but also almost as much fissile material
as its eastern neighbour to assemble an almost equal number of more nukes.
Fusion is used in the hydrogen bomb, in which fissile material
like that used in a simple nuclear warhead launches the process by which atomic nuclei fuse together to release energy.
