An important technical review marking progress in the independent development of core materials for fourth-generation nuclear power—the “Technical Appraisal Meeting on the WX‑H10 Nuclear‑Grade Graphite Solidification Process for Molten Salt Reactors”—was held at Henan Wuxing New Materials.
[Dahe CaiFang, Reporter Wang Leibin] Recently, an important technical review marking a significant step in the independent development of core materials for fourth-generation nuclear power—the “Technical Appraisal Meeting on the WX‑H10 Nuclear‑Grade Graphite Solidification Process for Molten Salt Reactors”—was held at Henan Wuxing New Materials Technology Co., Ltd. (hereinafter referred to as Wuxing New Materials). Renowned experts and scholars from leading domestic institutions in the fields of nuclear materials and graphite processing—including the Institute of Nuclear Energy Research at Tsinghua University, the Shanghai Institute of Applied Physics of the Chinese Academy of Sciences, Suzhou Institute of Thermal Engineering Co., Ltd., and the Shanxi Institute of Coal Chemistry of the Chinese Academy of Sciences—gathered at Wuxing New Materials to conduct a comprehensive review and evaluation of the WX‑H10 nuclear‑grade graphite’s production site, preparation process, performance test results, and documentation integrity.
It is understood that nuclear-grade graphite is a critical material for constructing fourth-generation nuclear reactors, such as high-temperature gas-cooled reactors and thorium-based molten-salt reactors, where it serves as a neutron moderator, a reflector, and a structural support for the reactor core. Molten-salt reactors use liquid high‑temperature molten salts as the coolant; these salts also carry the nuclear fuel and come into direct contact with the graphite, imposing even more stringent technical requirements on nuclear graphite. In addition to conventional properties—such as high purity, high density, high strength, high thermal conductivity, low thermal expansion, and long irradiation life—nuclear graphite for molten-salt reactors must also possess a fine pore structure to prevent the penetration and diffusion of liquid molten salt into the graphite.
At present, only a handful of companies worldwide are capable of mass-producing nuclear-grade graphite, and the export of related technologies and products is subject to stringent restrictions. Consequently, the process stabilization of WX‑H10 nuclear-grade graphite holds significant importance for advancing the independent development of nuclear graphite for molten-salt reactors in China.
At the appraisal meeting, the expert panel conducted a physical review of the WX‑H10 graphite blanks and an on-site inspection of the graphite manufacturing facility. They also heard a report on the process stabilization of WX‑H10 nuclear-grade graphite, covering key stages such as material production and preparation, machining and sampling, and analytical testing. Furthermore, the panel carried out a detailed examination of the production records, process documentation, quality assurance files, and test results for the WX‑H10 nuclear graphite. The expert panel concluded that the preparation process for WX‑H10 nuclear graphite is under control, the production records are traceable, and the material test results meet the design requirements.
The convening of this appraisal meeting marks the formal stabilization of the manufacturing process for WX‑H10 nuclear‑grade graphite, representing another step forward toward large‑scale production of this material. The expert panel’s professional review will provide a critical basis for decision‑making in the material’s subsequent applications.
According to reports, this appraisal conference was hosted by Wuxing New Materials, a company founded in 2007 and one of the few domestic enterprises to achieve end-to-end integrated production of high-purity graphite. In 2022, the company broke ground on a dedicated production line with an annual capacity of 30,000 tons of nuclear-grade graphite, backed by a total investment of RMB 360 million. In recent years, Wuxing New Materials has focused intensively on research and development of technologies for producing nuclear-grade graphite and, in 2025, filed patents related to methods and equipment for manufacturing such material.
