Title: The Innovations of Lars Halldahl
Introduction
Lars Halldahl is a notable inventor based in Vasterang, Sweden. He has made significant contributions to the field of nuclear fuel technology, holding 2 patents that showcase his innovative approaches. His work focuses on enhancing the manufacturing processes of nuclear fuel bodies and absorber plates for boiling water reactors.
Latest Patents
One of Halldahl's latest patents is a method of manufacturing sintered nuclear fuel bodies. This process involves pressing a powder of UO₂ containing 1-20 percent by weight Gd₂O₃ and up to 20 percent by weight U₃O₈ into a pressed body, followed by sintering. The Gd₂O₃ used in this method consists at least partly of monoclinic Gd₂O₃, which can be produced through heat treatment of cubic Gd₂O₃ at temperatures exceeding 1250°C. This innovative approach results in increased homogeneity regarding the solid solution of gadolinium in the UO₂ structure, particularly when sintering occurs in an atmosphere with an oxygen partial pressure higher than 10⁻⁷ atm at 1750°C.
Another significant patent by Halldahl is a method of manufacturing an absorber plate for a boiling water reactor. This absorber plate is designed to fit between fuel rod bundles in the reactor core. The manufacturing process involves anchoring a burnable neutron-absorbing material to at least one sheet by spraying the material in a finely-divided melted or plastically-formable state onto the sheet. This creates a solidified layer of the absorbing material, which is then enclosed in a protective casing.
