The special feature of this year’s map is that the total fissile material inventory, which decreased last year, has once again increased due to an increase in the amount of separated plutonium. The total inventory of HEU was 1,260 tons, equivalent to 19,680 warheads (an increase of 6 tons or about 80 warheads from last year), but this is due to a difference in the way the figures for “Other Non-nuclear Weapon Countries” are treated, and is not a substantial increase. However, the overall rising trend in separated plutonium continues, with an increase in plutonium for civilian use (mainly in France), bringing the total inventory to 552 tons, equivalent to 92,000 warheads (an increase of 8 tons or about 1,400 warheads from last year). As a result, the total inventory amount increased to equivalent to 111,680 warheads, an increase of around 1,480 warheads from last year (110,200 warheads).
