Summary

This webinar, hosted by the French Nuclear Energy Society (Sfen), provides an update on the JIMMY project, a small modular reactor (SMR) designed to decarbonize industrial heat. Antoine Guyot (CEO) and Mathilde Grivet (COO) present the company’s progress since 2022, including team growth to 80 employees, funding of €50 million, and the signing of contracts with suppliers like Urenco and Toyo Tanso. They emphasize the market need: industrial heat accounts for 75% of industry energy use, with 85% from fossil fuels, and no viable low-carbon alternatives currently exist. JIMMY’s reactor is a high-temperature gas-cooled reactor (HTR) with a thermal output of 60 MW, using TRISO fuel particles and helium coolant, designed for safety and simplicity. The company targets 80 sites in France and 700 in Europe, offering turnkey contracts to industrial clients. They have submitted construction license applications for a first reactor at a Cristal Union site and a fuel assembly facility in Creusot. Recent design optimizations aim to reduce costs and adapt to market conditions. The webinar concludes with next steps, including securing additional funding and advancing through the licensing process.
