“uranium enriched in the isotopes 235 or 233” means uranium containing the isotopes 235 or 233, or both, in an amount such that the abundance ratio of the sum of these isotopes to the isotope 238 is more than the ratio of the isotope 235 to the isotope 238 occurring in nature (isotopic ratio 0.72 per cent);

“other fissile materials” means previously separated americium-242m, curium-245 and -247, californium-249 and -251, neptunium-237, isotopes of plutonium other than -239 and any material containing the foregoing;

  • “effective gramme” of special or other fissile material means

  • (a) for plutonium isotopes and uranium-233, the isotope weight in grammes;

  • (b) for uranium enriched 1 per cent or greater in the isotope U-235, the element weight in grammes multiplied by the square of its enrichment expressed as a decimal weight fraction;

  • (c) for uranium enriched below 1 per cent in the isotope U-235, the element weight in grammes multiplied by 0.0001;

  • (d) for americium-242m, curium-245 and -247, californium-249 and -251 and neptunium-237, the isotope weight in grammes multiplied by 10;
