Abstract: A fuel element for a nuclear reactor having a zirconium-tin alloy cladding tube, with a thin coating of particles of enriched boron-containing compound burnable poison particles, such as ZrB.sub.2 deposited from a liquid suspension which includes an acrylic polymer binder material and isopropanol. Graphite lubricant particles can be included in the coating.
