Effective Kilogram

A unit of measure applied to quantities of nuclear material defined under the Agreement as follows:

(1) for plutonium, its weight in kilograms;
(2) for uranium with an enrichment of 0.01 (1 percent) and above, its weight in kilograms multiplied by the square of its enrichment;
(3) for uranium with an enrichment below 0.01 (1 percent) and above 0.005 (0.5 percent), its weight in kilograms multiplied by 0.0001;
(4) for depleted uranium with an enrichment of 0.005 (0.5 percent) or below; and
(5) for thorium, its weight in kilograms multiplied by 0.00005.

For example, 10 kilograms of uranium with an enrichment of 0.03 (3 percent) would equal 0.009 effective kilograms (10 kilograms × 0.0009).
