Isotope 239 Pu is formed in a nuclear reactor from fertile isotope 238 U, constituting more than 95% of uranium fuel (e.g.,, PWRs and BWRs require 3% – 5% of 235 U). Absorption of resonance or thermal neutron by the 238 U nucleus yields 239 U.

WebZirconium is refined using the van Arkel technique. By heating metal in an evacuated vessel with iodine, oxygen and nitrogen present as impurities are eliminated. On a … One disadvantage of metallic zirconium is that in the case of a loss-of-coolant accident in a nuclear reactor. Zirconium cladding rapidly reacts with water steam above 1,500 K (1,230 °C). Oxidation of zirconium by water is accompanied by release of hydrogen gas. This oxidation is accelerated at high temperatures, e.g. inside a reactor core if the fuel assemblies are no longer completely covered by liquid water and insufficiently cooled. Metallic zirconium is then oxidized by the protons
