A lid frame for a nuclear fuel assembly shipping container and a shipping container for nuclear fuel assemblies are provided. The shipping container includes a lower container having a cradle, an upper container detachably coupled to the lower container, and a base frame coupled to the cradle with at least one nuclear fuel assembly placed thereon. The lid frame includes a plurality of supports installed apart from each other so as to surround the nuclear fuel assembly placed on the base frame, a plurality of clamps separated from each other, coupled to the supports so as to be perpendicular to the supports, rotatably hinged to the base frame, and clamping the nuclear fuel assembly, and a plurality of gap compensators coupled to inner surfaces of the supports in order to compensate for a gap between the inner surfaces of the supports and the nuclear fuel assembly.
