FIELD: nuclear power engineering. SUBSTANCE: upper lattice is movable relative to duel assembly head and can, that is, upper lattice is free to displace together with fuel elements. Points of attachment of can and head are located only near three ribs of head and slots are provided near three remaining ribs to ensure easy movement of upper lattice lugs through them. EFFECT: improved design. 5 cl, 16 dwg
