Title: Claude Jaouen: Innovator in Ion Exchange Resin Immobilization

Introduction

Claude Jaouen, an inventive mind located in Guyancourt, France, has made significant contributions to the field of nuclear waste management through his innovative work. With a total of two patents to his name, his inventions have paved the way for advancements in the immobilization of ion exchange resins used in radioactive waste processing.

Latest Patents

Jaouen's latest patents focus on processes for the immobilization of ion exchange resins, a critical area in managing radioactive waste. The first invention pertains to a process that involves treating ion exchange resins with an aqueous solution containing nitrate and sodium ions. This process ensures that all sites in the anionic resins are saturated before their immobilization in cement, preferably of the CLK type. The careful orchestration of ion concentrations is aimed at maintaining a basic pH and achieving optimal saturation of cationic resin sites.

The second patent similarly addresses immobilization, specifically for ion exchange resins from the secondary circuits of nuclear reactors. This inventive process saturates the resins with sodium hydroxide in conditions that favor the release of ammonia, subsequently resulting in their stabilization with a hydraulic binder. This innovation significantly enhances the safety and efficacy of handling nuclear waste.
