摘要： The invention relates to the field of nuclear engineering and can be used in the manufacture of fuel rods and fuel assemblies for heavy liquid metal cooled reactors, and also in the manufacture of fuel rod simulators for use in irradiation devices designed to test the operability of real fuel assemblies. The present cladding 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 has an opening angle of from 22 to 40º (preferably from 30 to 40º) and the cross-section of the fin is in the shape of a trapezoid with rounded corners at the top of the trapezoid and smooth corners at the base of the trapezoid. Also disclosed are a fuel rod comprising the above cladding, 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 in the environment of a heavy liquid metal coolant such as lead or a eutectic of lead and bismuth.

摘要： A tight lattice fuel element assembly (20) for a pressurized-water cooled nuclear converter reactor includes a plurality of nuclearfuel elements (40) disposed in parallel, and forming a plurality of longitudinal flow channels (60), in a closely packed array. Axially spaced longitudinal fins (40) formed integrally on at least some of the fuel elements, at an angle with the fuel element axis, serve to divert coolant flowing longitudinally past the fuel elements between adjacent flow channels to promote mixing and even heating of the coolant. Each fin traverses the clearance between adjacent fuel elements, tangentially contacts the body of an adjacent fuel element, and is fixedly connected thereto. Sets of the axially spaced fins are fixedly connected to adjacent fuel elements, as described, in substantially the same transverse plane relative to the longitudinal axis of the fuel assembly. At the leading end of the fins, the relative flow rate diverted from adjacent flow channels alternates; and at the trailing end of the fins, the relative flow rate conveyed to adjacent flow channels also alternates; moreover, in a given flow channel the number of flow streams diverted and converged, at the leading and trailing fin edges, also alternates.
