Preparation and Characterization of Simulated Crud

Corrosion products, in the primary-side systems of pressurized-water reactors (PWRs), can be deposited on on a fuel's surfaces. Accumulation of these corrosion products, mainly composed of nickel ferrite, nickel oxide, and iron oxides, leads to an axially un-symmetric heat flux depression, which decreases the heat efficiency of a fuel. In order to solve this problem, a formation mechanism of nickel-iron mixed oxides and then a possible mechanism for a deposition of corrosion products should be elucidated. The present work deals with the synthesis of nickel-iron oxide powders and the measurements of characteristics of the as-prepared powders
