Title: Innovations by Hans Pirk in Radioactive Waste Management
Introduction
Hans Pirk is a notable inventor based in Maintal, Germany, recognized for his contributions to the field of radioactive waste management. With a total of three patents to his name, Pirk has developed innovative solutions aimed at improving the safety and efficiency of storing radioactive materials.
Latest Patents
One of Pirk's latest patents is a lining for bore holes in salt domes. This invention is designed to store radioactive materials securely within bore holes of salt domes. The bore holes are lined with superimposed tubular sections made of metallic material, which include an outer ring and an inner ring that are securely joined together by an intermediate ring made of an electrochemically nobler material. The joining of these tubular sections is achieved through welding the intermediate rings and inserting support rings into corresponding recesses of the outer rings.
Another significant patent by Pirk is a container for the final storage of radioactive wastes. This container is made from a uranium alloy that is less susceptible to corrosion compared to known containers made of uranium. It also does not exhibit anisotropic thermal expansion at high temperatures. The alloy consists of depleted uranium combined with 5 to 15 wt. % molybdenum, 2 to 15 wt. % copper, 1 to 5 wt. % zirconium, 0.5 to 5 wt. % chromium, 0.5 to 2 wt. % nickel, 0.5 to 1.5 wt. % niobium, and 0 to 5 wt. % iron, ensuring a robust and reliable solution for waste storage.
