Shaping the Future of Nuclear Energy
Together with Graphite

The International Nuclear Graphite Specialists Meeting (INGSM) was inaugurated in 2000 at the Oak Ridge National Laboratory in Tennessee, USA. Since then, it has been held annually in various countries, attracting leading experts, researchers, and industry professionals from around the world.

The conference serves as a global platform for presenting and discussing the full lifecycle of nuclear reactor-grade graphite, including its application in graphite-moderated reactor design, operation, and decommissioning. Through technical exchanges and collaborative dialogue, INGSM fosters the advancement of next-generation research and development in nuclear graphite technologies.

In 2026, INGSM will return to Japan for the first time in 23 years since its last hosting in 2003. The event will be co-organized by Toyo Tanso Co., Ltd. (*1) and the Japan Atomic Energy Agency (JAEA) (*2), with expected collaboration from The International Atomic Energy Agency (IAEA).

The most recent meeting was held in September 2025 at the IAEA Headquarters in Vienna, Austria, with approximately 120 participants in attendance.

Osaka, the host city for INGSM-26, offers excellent accessibility via Kansai International Airport and is renowned for its rich cultural heritage, diverse cuisine, and vibrant entertainment scene. As a dynamic international city, Osaka provides an ideal setting for global scientific exchange.

The call for abstracts and themes is tentatively scheduled for January 2026. Detailed information regarding the conference program, venue, and presentation submissions will be announced around April 2026. We warmly invite participants from across the globe to join us at INGSM-26—a valuable opportunity for international collaboration and knowledge sharing in the field of nuclear graphite.
