Title: John D. Hunn and TRISO Fuel Innovation.

Introduction

John D. Hunn is an inventor associated with Oak Ridge, Tennessee, and Ut-Battelle, Inc. His patent work addresses materials challenges in TRISO nuclear fuel, with a focus on improving fuel durability and performance.

Latest Patents

Hunn is credited with 1 patent: “TRISO Architecture for Palladium and Silicon Carbide Interaction Mitigation.” The invention introduces sacrificial silicon into a low-density carbon buffer layer. This silicon reacts with palladium released from the fuel kernel, limiting the palladium available to corrode the particle’s silicon carbide layer. The design may support longer fuel lifetimes and higher operating temperatures, potentially enabling greater burnup, lower fuel costs, and more efficient power production while improving fuel safety.

Career Highlights

Hunn’s listed patent reflects work on advanced nuclear fuel architecture and the mitigation of material degradation in TRISO fuel particles. The proposed buffer-layer design targets palladium corrosion, a factor that can contribute to fuel failure.
