DESCRIPTION OF THE PREFERRED EMBODIMENT FIG. 1 shows the apparatus of the invention. It shows a container for radioactive material seen in cross-section and the detail of another cross-section view of two adjacent chambers according to the invention. (1) is the thick metal barrel, usually made of steel, that constitutes the body of the container in cavity (2) in which the radioactive material is stored. The container is handled using trunnions (3) that are fastened onto barrel (1). A plurality of chambers (4) according to the invention cover the outer surface of barrel (1). Each chamber mainly comprises a metal section (5) that is hollow and closed along its length and has 4 long surfaces. Cooling fins (6) are located on the outer surface of said sections. Internal surface (7) is molded to the outer surface of barrel (1) such that it ensures perfect thermal contact. Inside each chamber a lead plate (8) is installed in contact with internal surface (7). The plate is covered with a protective steel sheet (9). The assembly consisting of section (5) and plates (8, 9) is fastened to barrel (1) using bolts (11). The remaining space inside section (5) is filled with a resin (10) that constitutes a neutron shield. Contained within (12) a passage tube may be seen that enables fastening from the outer surface of section (5) through the resin when said resin has been poured in section (5) before said section is fastened.
