Nano Nuclear Energy Awarded DOE GAIN Voucher for Reactor Design Support
The micro-reactor developer will leverage Oak Ridge National Laboratory’s SCALE/TSUNAMI tools for uncertainty analysis on its KRONOS MMR energy system.
April 09, 2026
Nano Nuclear Energy Inc., a Nevada-incorporated emerging growth company trading on the Nasdaq Stock Market under the ticker NNE, announced on April 9, 2026, that it has been awarded a Gateway for Accelerated Innovations in Nuclear voucher from the U.S. Department of Energy. The voucher, designated NE-26-38854, relates to the company’s KRONOS MMR energy system.
About the GAIN Program
The GAIN voucher program is administered by the Department of Energy to provide nuclear technology developers with access to national laboratory resources, technical expertise, and capabilities that support the commercialization of innovative nuclear technologies. The program is designed to help bridge the gap between concept development and deployment by connecting private-sector companies with the DOE’s national laboratory infrastructure.
Project Scope
The specific project supported by this voucher involves uncertainty quantification and sensitivity analysis for Nano Nuclear’s reactor design, utilizing Oak Ridge National Laboratory’s SCALE/TSUNAMI tools. SCALE is a widely used modeling and simulation suite for nuclear safety analysis and design, and TSUNAMI is a module within SCALE that performs sensitivity and uncertainty analysis — both critical steps in validating reactor performance and supporting the regulatory licensing process.
Company Background
Nano Nuclear is headquartered in New York City and is focused on developing portable micro-reactor technologies. The KRONOS MMR, or Micro Modular Reactor, is one of the company’s flagship reactor designs aimed at providing compact, deployable nuclear energy solutions.
The disclosure was signed by James Walker, the company’s Chief Executive Officer.
