Title: Innovations of Stevens S. Drake in Radioactive Waste Management
Introduction
Stevens S. Drake is a notable inventor based in Midland, MI (US), recognized for his contributions to the field of radioactive waste management. He holds a total of 3 patents that focus on innovative processes for encapsulating radioactive organic liquids.
Latest Patents
One of his significant patents is a process for encapsulating radioactive organic liquids in a resin. This method utilizes a cured resin system to encapsulate certain liquid low-level radioactive wastes, which are either solvents for or soluble in the uncured resin. The process involves diluting the waste with water to ensure that the amount of waste that partitions in the uncured resin system is less than what would hinder the cure rate or adversely affect the physical properties of the final product. Following this, the aqueous solution is uniformly dispersed in the curable resin system, which is then cured to form a solid with the waste solution embedded within. Another patent by Drake also addresses the encapsulation of radioactive organic liquids, converting them into a form suitable for burial. This process involves contacting the liquid with insoluble, swellable polymer particles to create swollen gelled particles, which are then dispersed in an unsaturated polyester or vinyl ester resin before being cured to a solid state.
