ABSTRACT:
A protective coating to reduce stress corrosion cracking of zirconium alloy sheathing in nuclear reactors. The coating is graphite based and includes ZrO.sub.2 and ethyl cellulose and acts as a sacrificial layer to immobilize fission products by formation of Zr.sub.x I.sub.y C type compounds which do not cause stress corrosion cracking.
