Toshiba Energy Systems Selected for Next-Generation Innovative Reactor Core Structure R&D and Demonstration Project

en.Wedoany.com Reported - September 9, 2026 - Toshiba Energy Systems & Solutions Corporation (Toshiba ESS) announced that it has been selected for the second round of public solicitation under the Ministry of Economy, Trade and Industry's FY2025 supplementary budget project "Support Program for Development and Construction Technology of Next-Generation Innovative Reactors and Supply Chain Development," undertaking the "Next-Generation Innovative Reactor Core Structure R&D and Manufacturing Demonstration Project (Phase 2)."

Following this selection, Toshiba Energy Systems will further expand its R&D efforts in the field of reactor internal structures, building on the six projects already selected in the first round. The company plans to collaborate with suppliers to conduct technology development and manufacturing demonstrations centered on the core structure of the "iBR," an innovative light water reactor it is developing and advancing toward practical application.

Toshiba Energy Systems stated that the iBR is positioned as an innovative light water reactor with high safety and the ability to coexist harmoniously with local communities. Through this demonstration project, the company will work to establish the manufacturing, supply, and maintenance capabilities required for future core structure production, build the relevant manufacturing infrastructure, and maintain and enhance the supply chain system.

According to available information, Toshiba Energy Systems was previously selected for this support program in August 2025, and six related projects were selected in August 2026. Together with the core structure R&D and manufacturing demonstration project selected this time, the company is continuously advancing technology development for next-generation innovative reactors and strengthening its industrial infrastructure.

Toshiba Energy Systems stated that it will continue to advance the technological development and application readiness of the innovative light water reactor iBR, while maintaining and strengthening the nuclear power-related industrial base and human resources base, thereby supporting stable power supply and the achievement of carbon neutrality goals.
