    Abstract: A method of coating a nuclear reactor component includes introducing the nuclear reactor component into a colloidal solution at a first rate to obtain an immersed component. The colloidal solution is a non-crosslinked mixture including a dispersed phase within a dispersion medium. The dispersed phase may include n-type metal oxide particles. The method additionally includes removing the immersed component from the colloidal solution at a second rate to obtain a wet component. The method also includes drying the wet component to obtain a dried component. The method further includes baking the dried component to obtain a coated component. Accordingly, the nuclear reactor component is provided with a protective layer that reduces or prevents the occurrence of corrosion.

    Abstract: Disclosed herein are zirconium-based alloys and methods of fabricating nuclear reactor components, particularly fuel cladding tubes, from such alloys that exhibit improved corrosion resistance in aggressive coolant compositions. The fabrication steps include a late-stage β-treatment on the outer region of the tubes. The zirconium-based alloys will include between about 1.30 and 1.60 wt % tin; between about 0.06 and 0.15 wt % chromium; between about 0.16 and 0.24 wt % iron, and between 0.05 and 0.08 wt % nickel, with the total content of the iron, chromium and nickel comprising above about .31 wt % of the alloy and will be characterized by second phase precipitates having an average size typically less than about 40 nm. The final finished cladding will have a surface roughness of less than about 0.50 μm Ra and preferably less then about 0.10 μm Ra.

    Abstract: An alloy according to example embodiments of the present invention may include zirconium, tin, iron, chromium, and nickel, with a majority of the alloy being zirconium. The composition of the alloy may be about 0.85-2.00% tin by weight, about 0.15-0.30% iron by weight, about 0.40-0.75% chromium by weight, and less than 0.01% nickel by weight. The alloy may further include 0.004-0.020% silicon by weight, 0.004-0.020% carbon by weight, and/or 0.05-0.20% oxygen by weight. Accordingly, the alloy exhibits reduced hydrogen absorption and improved corrosion resistance and may be used to form a fuel assembly component.
