Abstract | The invention relates to the field of nuclear energy and may be used in the manufacture of fuel rods (FR) and fuel assemblies. (FA) for reactors with a heavy liquid metal coolant (HLMC), as well as in the manufacture of FR simulators to be used in irradiation devices for real FR performance testing. The present cladding (1) of a fuel rod for a heavy liquid metal cooled reactor is in the form of a weldless tubular element with helically-coiled fins disposed on the outer surface of said element, which is made from a ferritic-martensitic chromium-silicon steel with a minimum ferrite grain size of 7 on the GOST 5639 scale, wherein each fin (2) has an opening angle of from 22 to 40? (preferably from 30 to 40?) and the cross-section of the fin (2) is in the shape of a trapezoid with rounded comers at the top of the trapezoid and smooth comers at the base of the trapezoid. Also disclosed are a fuel rod comprising the above cladding (1), and a fuel assembly. The technical result of the invention is an improvement in the performance characteristics of fuel rods and assemblies as a result of the long-term resistance of the cladding (1) in the environment of a heavy liquid metal coolant such as lead or a eutectic of lead and bismuth Most illustrative drawing: Figure 1. |
