ABSTRACT:
A pressurized water reactor nuclear fuel element has a tubular cladding container formed from zirconium or a zirconium alloy material without a protective coating or liner therefor, the cladding material containing less than 4 percent of alloying elements, including an oxygen content of less than 600 parts per million. The cladding contains a sealed nuclear fuel and a pressurized helium atmosphere which fills the gap between the fuel material and the inner wall of the cladding, the helium pressurized to between 150 to 500 pounds per square inch.
