... of which decrease over time). The expected amount of residual water (about 0.43 gram-mole) was also considered to be retained inside the cask/canister during fuel loading operations. The aging mechanisms considered for zirconium-based cladding include hydride reorientation and hydride-induced embrittlement...

..., pitting, intergranular attack, high corrosion rate and hydriding, may occur. Yet, there is no report in the public domain on the crevice corrosion of zirconium or any passive alloys in water-deficient organic environments. Zirconium's vulnerability in water-deficient organics results from its need...

... determination of hydrogen and hydride content in steels, stainless steels, and advanced materials. The non-destructive sensors operate at the electronic level making them even more sensitive than existing destructive analytical techniques at very low hydrogen concentrations. The sensors assess the electronic...

.... The role of temperature, scale, surface coatings and surface condition will also be considered. The paper should provide useful reference material for those interested in field and laboratory measurements of hydrogen flux, and the relation between the two. Certain non-metal hydrides are known...

... species called "nascent hydrogen" (H°) and tunnels interstitially through tubules of crystal lattices forming associative interactions with electrons. Nascent hydrogen is a short-lived, non-ionized, monatomic species at equilibrium with other atomic hydrogen species, such as hydrons (H + ) and hydrides (H...

... ABSTRACT Titanium heat exchanger tubes used in a wastewater environment at about 150 C for about seven years have been investigated. As can be predicted, no corrosion was observed on the inner surface of the tubes, but titanium hydrides were locally formed on the wastewater side (i.e., outer...

... demand. The most important basic technology is the Multi Stage Flash, where titanium is connected to copper and carbon steel components. To avoid galvanic coupling a cathodic protection system is used. One of the problems related to this technology is the formation of titanium hydrides...

... of hydrides. Hydrogen uptake can occur when the adherent surface oxide film is ruptured and allows the diffusion of atomic hydrogen. The loss of oxide film can occur due to mechanical abrasion, chemical reduction, or surface contamination. Several possible corrosion mechanisms will be discussed. Surface...

... INTRODUCTION ABSTRACT A new approach was developed for achieving a low electrochemical corrosion potential (ECP) on structural materials exposed to high temperature water, even without the addition of pure hydrogen. This approach uses metal hydride or alcohol acting as an alternate...
