Section: description

DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION The concrete shielding housing includes a pallet-like base 3 upon which is placed a cylindrical concrete shielding wall 4. A cover 5 forms part of the housing and lies upon the concrete shielding wall 4. The base 3 includes a square base plate 6 having feet 7 mounted at respective corners of the base plate 6 so that the base 3 is configured as a pallet accessible from beneath for moving the same from one location to another. The cylindrically formed concrete shielding wall 4 is placed upon the base 3 and is aligned by means of a suitable centering arrangement (not shown). The concrete shielding wall 4 is provided with openings 9 at the lower end thereof and these openings serve as lateral air inlet passages. The cover 5 lying upon the wall 4 includes an air outlet opening 11 at its center which is surrounded by perpendicular plates 12. A roof-like cover 13 extends over the air outlet opening 11 and is supported by supports 14 mounted on the cover 5. A fuel element container 15 is shown in phantom outline and is standing on the base plate 6 of the base 3. Axial bores 16 extend clear through the base plate 6 and communicate at their lower ends with the collection pan 17. The collection pan 17 is securely mounted to the lower side of the base plate 6. The collection pan 17 is formed so that it has a point of lowest elevation at the center thereof. At this deepest location 18 of the collection pan 17, a drain plug 19 is provided which threadably engages the pan. The drain plug permits moisture collected in the pan to be drained therefrom. Other modifications and variations to the embodiments described will now be apparent to those skilled in the art. Accordingly, the aforesaid embodiments are not to be construed as limiting the breadth of the invention. The full scope and extent of the present contribution can only be appreciated in view of the appended claims.
