Latest Patents
Tegman's latest patents include a method for containing radioactive or other dangerous waste materials. This method involves using a bonding compound that is resistant to leaching by water, all within a gas-tight container. The process includes converting the material through hot isostatic pressing (HIP) into a dense body. The design features a cylindrical container with a corrugated bellows-like wall, preventing dangerous materials from filling the annular spaces formed by the corrugations through the use of an internal barrier means. Additionally, he has developed a method for preparing spent nuclear fuel rods for long-term storage. In this method, spent fuel rods are enclosed in a copper body, embedded in copper powder within a copper container that is sealed with a copper lid. The entire assembly undergoes isostatic compression to form a coherent dense mass, ensuring the safety of the stored materials.
