MACHINE-TOOL FOR PRODUCING FUEL ASSEMBLIES FROM FUEL ELEMENTS

摘要

FIELD: producing fuel assemblies from fuel elements. ^ SUBSTANCE: fuel elements held in accumulating tank installed under machine-tool incorporatying two-coordinate positioner and linear drive with pusher provided with collet chuck are vertically inserted in parallel into fuel assembly frame. Distance between spacer grids is increased from 250 to 500 mm and more. ^ EFFECT: reduced material input due to shorter distance between fuel assembly spacer grids. ^ 5 cl, 6 dwg
