Zirconium is a chemical element with the symbol Zr‚ atomic number 40 and atomic mass of 91.224. The name of zirconium is taken from the mineral zircon‚ the most important source of zirconium. It is a lustrous‚ grey-white‚ strong transition metal that resembles titanium. Zirconium is mainly used as a refractory and opacifier‚ although minor amounts are used as alloying agent for its strong resistance to corrosion. Zirconium forms a variety of inorganic and organometallic compounds such as zirconium

wind streams. The repercussions of the disaster are only now being better understood today. The reactor type at Chernobyl was a RBMK type reactor. The reactor is a vertically oriented reactor that uses graphite as an insulator which also caused problems due to the combustibility of the graphite that was used. "The reactor fuel is zirconium alloy clad uranium oxide enriched to 2.0% U-235" (Mosey). The RBMK reactor also has two 500MWt reactors which operate safely at 100% power of 1000MWt. "Reactor
