The density of uranium is 19 grams/cc, so 1000 grams will be 52.6 cc which is about 10 teaspoons.
If 1 teaspoon has a volume of 3,7 cm3 and the density of uranium is ca. 19,05 g/cm3 a teaspoon may contain ca. 70,5 g of uranium.
1 kg of uranium-235 is equivalent to 24.10ex.6 kWh.
Approx. 125 US $ for 1 kg of unrefined uranium oxide U3O8.
Probably approx. 40 kg of enriched uranium.
A nuclear bomb typically contains less than 100 pounds of highly-enriched uranium. However, even a small amount of uranium can cause a powerful explosion when properly assembled.
Uranium dioxide, nuclear grade, not enriched has a value greater 100 US $/kg.
Depending very much on the chemical or physical form, purity, enrichment, etc. For nuclear grade powder of natural uranium dioxide: ca. 100 $/kg.
Approx. 90 000 US $ for 1 000 kg of unrefined uranium octaoxide (U3O8).
Approx. 70 US $ for 1 kg of nuclear reactor grade uranium doxide (with natural uranium); the enriched uranium is more expensive, depending on enrichment.
approx. 120 US $ for 1 kg of unrefined uranium (exprimed as U3O8)
The price of 1 kg uranium octaoxide (U3O8) is approx. 90 US $/kg.
abundance of uranium in the earth crust; 2,5-3 ppm (mg/kg) abundance of uranium in the sea water: ca. 3 ppb (?g/kg)
