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.

Since unenriched uranium fuel accumulates a lower density of fission products than enriched uranium fuel, however, it generates less heat, allowing more compact storage. [4] While deuterium has a lower neutron capture cross section than protium , this value isn't zero and thus part of the heavy water moderator will inevitably be converted to ...
Uranium(III) chloride is a green crystalline solid at room temperature. UCl 3 melts at 837 °C and boils at 1657 °C. Uranium(III) chloride has a density of 5500 kg/m 3 or 5.500 g/cm 3. Its composition by weight: Chlorine: 30.84% Uranium: 69.16%. Its formal oxidative states: Chlorine: −1 Uranium: +3
Depleted uranium consists mainly of 238 U which decays by alpha decay with a half-life of 4.468(3) × 10 9 years. Even if the uranium contained 235 U which decays with a similar half-life of about 7.038 × 10 8 years , both of them would still be regarded as weak alpha emitters and their radioactivity is only hazardous with direct contact or ...
In general, uranium salts exhibit nephrotoxicity. Normal commercial stocks from depleted uranium have typical specific activity 0.37–0.51 microcuries per gram (14–19 kBq/g), too weak to harm from outside the body. [8] However, uranyl acetate is very toxic if ingested, inhaled as dust, or absorbed through cut or abraded skin. [citation needed]
MOX fuel is an alternative to the low-enriched uranium fuel used in the light-water reactors that predominate nuclear power generation. For example, a mixture of 7% plutonium and 93% natural uranium reacts similarly, although not identically, to low-enriched uranium fuel (3 to 5% uranium-235).
