Between the heavy construction and the metal skin is a narrow, inaccessible gap. The dimensions of this gap must remain constant. If it is not, then a shift has occurred and there is a chance of leakage of the skin. Philippsburg wishes to be assured that the gap remains constant. Techniques for this were not available.
Triangulation now makes it possible to measure the distance between the two skins from the outside.
The separated actinides can be included in the fuel of a special actinides burner. The waste from such an actinides burner which only exists on the drawing-board as yet has a characteristic as shown by the upper green line. In principle, this waste can also be recycled further, so that the radiotoxicity curve of the eventual waste will lie somewhere in the shaded area, depending on the recycling strategy chosen.
