VERFAHREN ZUM ZERLEGEN VON BRENNELEMENTEN

摘要

In disassembling an irradiated nuclear fuel or breeder element, which consists of individual rods arranged in a casing 1 and held in grid-type spacers, a first cut I is made at the point of the greatest neutron-induced swelling of the fuel rods and a first part of the casing 1 is removed with the spacer grids attached thereto. Thus the spacers need only be drawn over rod portions of smaller diameter thereby avoiding a greater force expenditure and damage to the individual rod casing tubes resulting from this.
