Project Overview
In May 2021, the University of Illinois Urbana-Champaign (UIUC) submitted to the NRC a Letter of Intent to submit an application for a construction permit for a high-temperature gas-cooled reactor. The proposed research reactor would be based on NANO Nuclear Energy Inc. technology, and would utilize TRISO particle fuel, helium gas coolant, and graphite moderator. The reactor would be located on UIUC’s campus in Urbana-Champaign, Illinois, and would have a molten salt secondary loop providing electrical power conversion capability for campus use. UIUC is engaged in pre-application activities with the NRC.
For more information, please see the UIUC High-Temperature Gas-Cooled Reactor pre-application documents (NRC Project No. 99902094).
