WebZirconium Carbonate It is mainly used as cosmetic additives and waterproofing agents, flame retardants, sunscreens, and surface additives for fibers and paper. It is an important raw material for the textile, paper, coating, and cosmetics industries. 3. … 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

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.
