 | Fissile material that has been removed from the military production cycle and is redundant is steadily increasing. |
| We should also consider devising arrangements to ensure that this material is in fact used for non-explosive purposes by confirming both the amount of the material intended for such use and the actual area of use. |
| The entire field of weapons usable fissile material needs to be addressed in a comprehensive manner in order to establish an international norm to define obligations and guide actions for states in dealing with weapons usable fissile material. |
| IPFM International Panel on Fissile Materials - Fissile Materials & Nuclear Weapons (1920 words) |
| The fission of one kilogram of fissile materials – the approximate amount that fissioned in both the Hiroshima and Nagasaki bombs – releases an energy equivalent to the explosion of about 18 thousand tons (18 kilotons) of chemical high explosive. |
| The minimum amount of material needed for a chain reaction to be sustained is defined as the critical mass of the fissile material. |
| When the temperature of the fissioning materials inside the pit reaches 100 million degrees, it can ignite the fusion of tritium with deuterium, which produces a burst of neutrons that "boost" the fraction of fissile materials fissioned and thereby the power of the explosion. |
