Abstract
Official abstract text for this publication.
A zirconium alloy cladding tube for use in a water cooled nuclear reactor under normal operating conditions and under high temperature oxidation conditions is described. The cladding tube has a coating uniformly deposited thereon. The coating, which may be up to 300 microns thick, is selected from the group consisting of chromium, a chromium-based alloy, and combinations thereof.
First claim
Opening claim text (preview).
What is claimed is: 1 . A cladding tube for use in a water cooled nuclear reactor comprising: a cladding tube formed from a zirconium alloy and having a coating uniformly deposited thereon, the coating selected from the group consisting of chromium, a chromium-based alloy, and combinations thereof. 2 . The cladding tube recited in claim 1 wherein the coating is up to 300 microns thick. 3 . The cladding tube recited in claim 1 wherein the coating is a Cr-based alloy comprising at least one element selected from the group consisting of silicon, yttrium, aluminum, titanium, niobium, zirconium, and transition metal elements, at a combined content of 0.1 to 20 atomic %. 4 . The cladding tube recited in claim 1 wherein the coating is a Cr-based alloy comprises 80 to 99 atom % of chromium.
