Title: The Innovative Contributions of Richard L. Propst
Introduction
Richard L. Propst is a notable inventor based in Ogden, Utah, recognized for his significant contributions to the field of materials science. He holds 2 patents that focus on advanced processes for producing high-purity zirconium materials, which are essential in the nuclear industry.
Latest Patents
One of his latest patents is titled "Combined ultra slow electron beam and vacuum arc melting for barrier." This innovative process is designed to create a very pure and homogeneous zirconium material for lining the interior of zirconium alloy fuel element cladding. The method involves forming consumable feed material from generally virgin sponge material, melting it in a multiple swept beam electron beam furnace at a feed rate between 0.1 and less than about 1.0 inch per hour, and subsequently vacuum arc melting the electron beam melted material.
Another significant patent by Propst is "Ultra slow EB melting to reduce reactor cladding." This process aims to produce material for lining reactor fuel element claddings. Instead of using unalloyed zirconium, this invention proposes an alloy liner for the cladding. The ultra-slow electron beam melting of zirconium minimizes metallic impurities, thereby reducing solid solution strengthening and second phase formation. This innovation also controls oxygen levels and incorporates a small amount of tin to enhance the fabricability of the alloyed liner material.
