No, it is not possible to fill 1 kg of uranium in a one teaspoon volume because uranium is a dense material and would require a much larger volume than a teaspoon to accommodate its mass.
1 kg of uranium-235 is equivalent to 24.10ex.6 kWh.
Approx. 125 US $ for 1 kg of unrefined uranium oxide U3O8.
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.
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)
0.005 kg of water in a teaspoon.
Approx. 120 USD for 1 kg of unrefined oxide U3O8.
About 33 kilograms of highly enriched uranium (HEU) is typically used in a 10 kiloton fission bomb.
Depending very much on the chemical or physical form, purity, enrichment, etc.For nuclear grade powder of natural uranium dioxide: ca. 100 $/kg.
