Method of protecting a zirconium-alloy cladding tube of a nuclear-reactor fuel rod against attack by radioactive fission products, such as iodine especially, which includes applying an internal pressure to the cladding tube at a temperature of from 300 DEG to 500 DEG C. so as to deform the cladding tube, depending upon the geometric dimensioning thereof, in the elastic range and up to nearly the yield point thereof and, while this condition exists, reacting a medium previously introduced into the interior of the cladding tube, with the inner surface of the cladding tube to form a protective layer.
