Nano Nuclear Energy Inc. announced on April 9, 2026, that it has been awarded a GAIN Voucher by the U.S. Department of Energy to collaborate with Oak Ridge National Laboratory on uncertainty quantification for its KRONOS MMR™ Energy System.
Key takeaways
The company was awarded a Gateway for Accelerated Innovations in Nuclear (GAIN) Voucher, NE-26-38854, by the U.S. Department of Energy.
The voucher supports collaboration with Oak Ridge National Laboratory to apply the SCALE/TSUNAMI code suite for uncertainty quantification and sensitivity analysis of the KRONOS MMR™ Energy System.
The collaboration aims to develop a validated uncertainty quantification framework to demonstrate safety margins, performance reliability, and licensing readiness for the reactor design.
This is the company's second GAIN voucher overall and the first specifically for its KRONOS MMR™ Energy System.
The voucher provides access to DOE laboratory expertise and capabilities but does not involve direct financial awards to the company.
The resulting analysis framework is expected to accelerate KRONOS MMR™ design maturation and contribute to commercialization of scalable advanced microreactor technology.
