“It is truly an honor for us to be awarded a GAIN NE voucher to further validate and improve upon our novel heat exchanger concept,” said Prof. Massimiliano Fratoni, Ph.D., Senior Director and Head of Reactor Design of NANO Nuclear Energy. “The heat exchanger is an enabling component of our patent-pending ‘ZEUS’ microreactor design, allowing us to keep the system size compact and simplifying its design to match our vision of developing portable, secure and reliable nuclear microreactors to benefit mankind. I look forward to working alongside the leading technical personnel at the Idaho National Laboratory to further refine and progress its design, and I anticipate that this partnership will be pivotal in the future deployment of our innovative microreactor solutions.”

With this voucher award, NANO Nuclear will collaborate with INL to conduct an independent evaluation of the heat exchanger design for the ‘ZEUS’ microreactor. Designed to fit within a 45-foot high-cube container, the patent-pending ‘ZEUS’ microreactor features a power conversion unit capable of generating 1 to 2 MW of electricity without the use of fluid coolant.

A key aspect of this design is its ability to dissipate heat from the reactor vessel using an open-air Brayton cycle. The collaboration with INL will involve the development of a computational model to analyze and verify critical attributes of the heat exchanger essential to reactor operations, providing a comprehensive assessment of its performance.

“The Department of Energy’s GAIN program is a major driver of nuclear innovation in the United States, and we are delighted to collaborate with the Idaho National Laboratory, with whom NANO Nuclear already maintains good relations, to further strengthen this critical component for our patent-pending ‘ZEUS’ microreactor design,” said Jay Yu, Founder and Chairman of NANO Nuclear Energy. “Our prior experience with INL, where they conducted a pre-conceptual review of our ‘ODIN’ microreactor design, was extremely valuable to us, and we are eager to take the next step in advancing our technology in collaboration with one of the world’s leading nuclear research institutions.”

The U.S. Department of Energy Office of Nuclear Energy (DOE-NE) launched the GAIN program in 2016 to offer technical, regulatory, and financial support to help the nuclear industry advance innovative technologies toward commercialization. Since its launch, the program has awarded over 100 NE vouchers.

GAIN NE voucher recipients do not receive direct financial awards as the vouchers provide funding to DOE laboratories (in this case INL) to help businesses overcome critical technological and commercialization challenges. These vouchers thus grant innovators like NANO Nuclear access to the extensive nuclear research expertise and capabilities across the DOE national laboratory complex.

“The GAIN voucher gives us the opportunity to develop a model to simulate a critical part of the design in a timely and efficient manner,” said James Walker, Chief Executive Officer and Head of Reactor Development of NANO Nuclear Energy. “It enables us to work alongside the world-class personnel at Idaho National Laboratory and leverage their expertise to model the behavior of this key design choice of our novel heat exchanger concept. This model will serve us well in the future as we integrate it with other design elements to optimize the design for real world applications.”
