In 2026, the global new energy nuclear power industry entered a period of intensive construction. With the official commissioning of multiple small modular reactors (SMR) and fourth-generation high-temperature gas-cooled reactor projects in Asia, Europe and North America, the market demand for nuclear-grade graphite materials has ushered in explosive growth. According to the latest research data released by international nuclear energy industry institutions, the global nuclear-grade graphite market scale reached 196 million US dollars in the first half of 2026, a year-on-year increase of 14.3%, and it is expected to break through 523 million US dollars by 2032, with a compound annual growth rate of 14.16%, becoming the fastest-growing segmented track in the global high-end graphite industry.
Nuclear-grade graphite is a special high-purity carbon material used in nuclear reactor core structures, thermal insulation systems and neutron moderator components, with extremely strict technical standards different from aerospace and semiconductor graphite products. Nuclear-grade graphite needs to maintain stable structural performance, low neutron absorption rate and excellent radiation resistance under long-term high-temperature and nuclear radiation environments, and the product purity, structural uniformity and stress stability have reached the highest level of industrial graphite standards. At present, only a few enterprises in China, Japan and Germany have mature nuclear-grade graphite deep-processing technology in the world.
The core driving force of the rapid growth of the nuclear-grade graphite market is the global energy structure transformation and the iterative upgrading of nuclear power technology. In order to achieve carbon neutrality goals, major global economies have accelerated the layout of clean nuclear power energy. Small modular reactors (SMR) have become the mainstream development direction of new nuclear power projects due to their small size, high safety and flexible deployment. Each SMR project needs to be equipped with a large number of high-purity nuclear-grade graphite thermal insulation components and structural parts, bringing continuous incremental demand to the industry.
In terms of technical iteration, the global nuclear-grade graphite industry is developing towards ultra-low impurity, ultra-low porosity and ultra-long service life. Traditional nuclear-grade graphite products have the problems of high porosity and easy radiation aging, which limits the service life of nuclear reactor equipment. The new generation of nuclear-grade graphite adopts ultra-fine grain isostatic pressing technology and multi-cycle high-temperature deep purification process, which effectively reduces internal porosity and trace impurities, improves radiation resistance and structural stability, and extends the service life of nuclear reactor components by more than 30%.
In terms of global competition pattern, Chinese enterprises have absolute leading advantages in the field of nuclear-grade graphite deep processing. Relying on years of technical accumulation and complete industrial supporting system, China has become the world's largest producer and exporter of nuclear-grade graphite components, occupying more than 65% of the global market share. Japanese and German enterprises are limited by insufficient production capacity and high production costs, and their market share continues to shrink, unable to meet the booming global market demand.
Huixian Jincheng Abrasive & Graphite Mold Factory has long been committed to the R&D and customized production of nuclear-grade auxiliary graphite components, and has accumulated rich technical experience in nuclear-grade graphite purification, precision processing and anti-radiation treatment. The company focuses on the production of nuclear reactor thermal insulation graphite components, support structural parts and vacuum test graphite fixtures, which are widely used in SMR small modular reactors and high-temperature gas-cooled reactor supporting projects at home and abroad.
In terms of technical standards, Jincheng Graphite's nuclear-grade auxiliary graphite products adopt ultra-fine grain high-density isostatic graphite blanks, after four-stage high-temperature halogen deep purification and multi-cycle vacuum impregnation treatment, the total impurity content is stably controlled below 3ppm, the internal porosity is less than 0.5%, and the product has excellent low neutron absorption rate and radiation aging resistance, fully meeting the international nuclear power equipment manufacturing standards. Compared with ordinary industrial graphite products, the company's nuclear-grade graphite components have more stable structural performance in long-term high-temperature and radiation environments, with a service life 40% longer than the industry average.
At present, Jincheng Graphite's nuclear-grade graphite supporting products have been supplied to many nuclear power equipment manufacturing enterprises and nuclear energy research institutions in China, Southeast Asia and the Middle East, providing stable core component support for global new nuclear power project construction. The company's professional customized service capability can carry out personalized structural design and performance optimization according to the parameters of different nuclear reactor projects, meeting the differentiated needs of global nuclear power equipment manufacturers.
With the continuous acceleration of global nuclear power new project construction, the market demand for high-performance nuclear-grade graphite components will continue to rise. Jincheng Graphite will continue to increase R&D investment in nuclear-grade graphite anti-radiation technology and long-life optimization technology, further improve product performance indicators, and contribute to the high-quality development of the global clean nuclear power industry.
