Uranium is notable for the extremely high density of its metallic form: at 19.1 grams per cubic centimetre (0.69 lb/cu in), uranium is 68.4% more dense than lead. Depleted uranium, which has about the same density as natural uranium, is used when this high density is desirable but the higher radioactivity of natural uranium is not.
Total weight of nuclear material and bomb was 98.8 - 100.2 kg Hiroshima's "Little Boy" gravity bomb: 13–18 54–75 Gun type uranium-235 fission bomb (the first of the two nuclear weapons that have been used in warfare). 64 kg of Uranium-235, about 1.38% of the uranium fissioned Nagasaki's "Fat Man" gravity bomb 19–23 79–96
A 1 inch tall uranium fuel pellet is equivalent to about 1 ton of coal, 120 gallons of crude oil, or 17,000 cubic feet of natural gas. [15] In light-water reactors , 1 kg of natural uranium – following a corresponding enrichment and used for power generation– is equivalent to the energy content of nearly 10,000 kg of mineral oil or 14,000 ...
Natural uranium is made weapons-grade through isotopic enrichment. Initially only about 0.7% of it is fissile U-235, with the rest being almost entirely uranium-238 (U-238). They are separated by their differing masses. Highly enriched uranium is considered weapons-grade when it has been enriched to about 90% U-235. [citation needed]
kilogram per cubic decimetre (kg/dm 3) gram per cubic centimetre (g/cm 3) 1 g/cm 3 = 1000 kg/m 3; megagram (metric ton) per cubic metre (Mg/m 3) In US customary units density can be stated in: Avoirdupois ounce per cubic inch (1 g/cm 3 ≈ 0.578036672 oz/cu in) Avoirdupois ounce per fluid ounce (1 g/cm 3 ≈ 1.04317556 oz/US fl oz = 1.04317556 ...
Plants absorb some uranium from soil. Dry weight concentrations of uranium in plants range from 5 to 60 parts per billion, and ash from burnt wood can have concentrations up to 4 parts per million. [30] Dry weight concentrations of uranium in food plants are typically lower with one to two micrograms per day ingested through the food people eat ...
TNT equivalent is a convention for expressing energy, typically used to describe the energy released in an explosion.The ton of TNT is a unit of energy defined by convention to be 4.184 gigajoules (1 gigacalorie), [1] which is the approximate energy released in the detonation of a metric ton (1,000 kilograms) of TNT.
The highest grade uranium deposits are found in the Athabasca Basin in Canada, including the two largest high grade uranium deposits in the world, Cigar Lake with 217 million pounds (99,000 t) U 3 O 8 at an average grade of 18% and McArthur River with 324 million pounds (147,000 t) U 3 O 8 at an average grade of 17%. These deposits occur below ...
