Uranium-235 ( U or U-235) is an isotope of uranium making up about 0.72% of natural uranium. Unlike the predominant isotope uranium-238, it is fissile, i.e., it can sustain a nuclear chain reaction. It is the only fissile isotope that exists in nature as a primordial nuclide. Uranium-235 has a half-life of 703.8 million years. It was discovered in 1935 by Arthur … WebWith a complete combustion or fission See 'nuclear fission'., approx. 8 kWh of heat can be generated from 1 kg of coal, approx. 12 kWh from 1 kg of mineral oil and around 24,000,000 kWh from 1 kg of uranium-235. Related to one kilogram, uranium-235 contains two to three million times the energy Ability to do work or diffuse heat. The unit of ...

It has a half-life of 704 … WebMay 4, 2015 · It's not just uranium. There are four isotopes whose half-lives are long enough that they can be primordial and whose half-lives are not so long that they don't produce much heat. These four isotopes are Uranium 235, with a half-life of 0.703 billion years, Potassium 40, with a half-life of 1.277 billion years,
WebEnrichment: Product Assay [wt-% U-235] Weight-percent of the fissile isotope uranium-235 in the uranium contained in the product stream (enriched uranium hexafluoride) of the enrichment plant. Values for use in pressurized water reactors (PWR) range between 3.6% and 4.1%, and for use in boiling water reactors (BWR) between 3.0% and 3.2%. WebThe critical mass for lower-grade uranium depends strongly on the grade: with 20% 235 U it is over 400 kg; with 15% 235 U, it is well over 600 kg. The critical mass is inversely proportional to the square of the density. If the density is 1% more and the mass 2% less, then the volume is 3% less and the diameter 1% less.

WebU-235 is the only naturally occurring isotope which is thermally fissile, and it is present in natural uranium at a concentration of 0.7%. U-238 and Th-232 are the main naturally-occurring fertile isotopes. The probability that fission or any another neutron-induced reaction will occur is described by the neutron cross-section for that reaction. the tight traductionWebOne kilogram of uranium-235 can theoretically produce about 20 terajoules of energy (2 × 10 13 joules ), assuming complete fission; as much energy as 1.5 million kilograms (1,500 tonnes) of coal.
