Title: Kecheng Jiang: Advancing Fusion Reactor Blanket Technology

Introduction

Kecheng Jiang is an inventor associated with Hefei, China, and the Chinese Academy of Sciences. His patent work includes a solid lithium-lead blanket concept for fusion reactors, designed to support neutron multiplication and tritium breeding.

Latest Patents

Jiang is credited with 1 patent: “Solid lithium-lead blanket for fusion reactor.” The invention uses solid lithium-lead alloy as both a neutron multiplier and a tritium breeder, arranged as a unitary or binary pebble bed within a structural skeleton. A coolant removes heat deposited in the alloy through interactions with fusion neutrons, while purge gas flowing through the pebble bed carries tritium out of the reactor.

The patent describes a low proportion of lead atoms intended to keep the alloy solid during normal operation and accident conditions. Its design aims to support tritium self-sufficiency without requiring beryllium to meet tritium-breeding requirements.

Career Highlights

Jiang’s listed patent highlights work on materials and blanket design for fusion energy systems. The proposed approach combines heat removal, neutron multiplication, and tritium breeding in a solid-state configuration.
