Latest Patents

One of Zheng’s latest listed patents is titled “Method of Operating a Pressurized-Water Nuclear Reactor Allowing Same to Pass from a Plutonium Equilibrium Cycle to a Uranium Equilibrium Cycle and Corresponding Nuclear Fuel Assembly.” The invention describes operating a reactor through plutonium equilibrium cycles, followed by transition cycles in which plutonium-equilibrium fuel assemblies are progressively replaced with transition assemblies and then uranium-equilibrium assemblies. The process culminates in operation through at least one uranium equilibrium cycle.

This staged approach addresses the change in fuel composition over successive reactor cycles. The patent also covers a corresponding nuclear fuel assembly.
