Project Overview

In May 2021, the University of Illinois Urbana-Champaign (U. of I.) 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 U. of I.'s campus in Urbana-Champaign, Illinois, and would have a molten salt secondary loop providing electrical power conversion capability for campus use. U. of I. engaged in pre-application activities with the NRC prior to its submission of a construction permit application in March 2026

For more information, please see the U. of I. High-Temperature Gas-Cooled Reactor pre-application documents (NRC Project No. 99902094).
