Title: Bernard Guillaume and His Patent for Treating Basic Aqueous Effluents

Introduction

Bernard Guillaume is an inventor associated with Grigny, France, and the Commissariat à l’énergie atomique et aux énergies alternatives (CEA). His patent work addresses the treatment of basic aqueous effluents containing plutonium and potentially uranium.

Latest Patents

Guillaume is associated with 1 patent, titled “Process for the Treatment of Basic Aqueous Effluents.” The invention describes concentrating the effluents through evaporation under reduced pressure while keeping the temperature low enough to substantially avoid plutonium precipitation. It identifies evaporation at 50–80 °C as an advantageous approach and describes obtaining a concentration factor of at least six. The process is intended for aqueous effluents produced by alkaline washing of organic solvents used in facilities that reprocess irradiated nuclear fuel.

Career Highlights

The patent reflects work on a specialized challenge in nuclear-fuel reprocessing: treating contaminated aqueous waste while limiting plutonium precipitation during concentration. Guillaume’s listed organizational affiliation is the CEA, a French research institution focused on energy, defense, and related scientific fields.

Collaborations

Alain Aspart and Jean-Paul Moulin are identified as Guillaume’s coworkers in connection with the information provided.

Conclusion

Bernard Guillaume’s patent documents a process for concentrating basic aqueous effluents containing plutonium, with potential application to waste streams from nuclear-fuel reprocessing.
