Moreover, NANO Nuclear believes there is significant potential for this technology to be separately commercialized within a year as a component for liquid metal and all molten salt–based nuclear reactors. Most advanced nuclear reactor designs utilize liquid-metals and molten salts for cooling and heat transfer functions in the fission and fusion energy industries, as well as in the advanced materials, space exploration, marine propulsion, and high-temperature and industrial process sectors.  Some groups that employ technologies where NANO Nuclear’s ALIP technology could potentially be utilized include TerraPower, Oklo, Commonwealth Fusion Systems, Tokamak, NASA, The Department of Energy, GE-Hitachi and Rolls-Royce Marine.

“Although based on known physical principles, this technology is cutting edge,” said Prof. Eugene Shwageraus, Lead of Nuclear Reactor Engineering of NANO Nuclear Energy. “It allows pumping of electrically conducting liquids without moving parts. The technology will offer a major advantage to our ‘ODIN’ design. Forced circulation of coolant at normal operation will allow a substantial increase in the core power density, while improving reliability and reducing maintenance requirements. The low flow resistance of these pumps also improves the passive decay heat removal capability using natural circulation – another key feature of the ODIN reactor design.”

The SBIR program is a federal initiative designed to support small businesses in conducting research and development with strong potential for commercialization. By funding these projects, the SBIR program aims to stimulate technological innovation and facilitate the transition of research into viable products and services.  SBIR Phase I focuses on feasibility and technical merit, Phase II involves further development and prototype creation, and Phase III centers on commercialization, requiring external funding to bring the innovation to market.

The SBIR Phase III project acquired by NANO Nuclear integrates several previous SBIR efforts, specifically:

• Grant Number DE-SC0019835: Development of a Small Electromagnetic Pump for Molten Salt.
• Grant Number DE-SC0022805: Software for Multiphysics Analysis and Design of Annular Linear Induction Pumps.

Grant Number DE-SC0013992: Computational Tools for the Design of Liquid Metal Thermomagnetic Systems.

“NANO Nuclear is an emerging leader in the microreactor technology space.  I am very impressed with their world class team of nuclear engineers, former senior U.S. military, government leaders and corporate professionals” said Dr. Carlos O. Maidana, CEO and Founder at Maidana Research.  “I am excited that the NANO Nuclear team sees the value of this technology and am delighted to work with them in the SBIR Phase III program as we seek to bring this technology to market in the near term.”

The aim of the Phase III program is to enhance thermal management systems through the development of advanced electromagnetic pump solutions.  The approach integrates innovative software, robust hardware designs, and optimized manufacturing processes to address challenges in high-efficiency thermal fluid management for clean energy and high-temperature industrial processes. This technology is particularly applicable to NANO Nuclear’s ‘ODIN’ microreactor design, as its design aims to take maximum advantage of natural convection of coolant for heat transfer to the power conversion cycle at full power and for decay heat removal during reactor shutdown, operational transients, and off-normal conditions.

“This is an exciting development for NANO Nuclear, as we believe this ALIP technology will enable even greater efficiency and savings for our ‘ODIN’ microreactor once it enters commercialization,” said Jay Jiang Yu, Executive Chairman and President of NANO Nuclear Energy. “Dr. Maidana’s designs not only align seamlessly with our commitment to sustainability but also have the capability to complement and enhance our microreactor designs, driving us closer to a future of more efficient and innovative energy solutions. Beyond the application for our own microreactors, which we believe will give our designs a competitive edge, our goal is to also see this technology commercialized within a year, which could lead to revenue generation by our company. We will also look to acquire other complimentary assets like this, which creates the potential for near term revenues and helps further de-risk the company.”

Certain high-temperature nuclear reactors, like the NANO Nuclear’s proprietary portable advanced microreactor ‘ODIN’, make use of molten salts or molten metals and their alloys for cooling the reactor core due to their favorable heat transfer properties. Pumping of these liquids by classical mechanical radial or axial pumps is, however, technologically challenging and the lifetime of such devices is relatively short. It is known that electromagnetic pumps have several advantages over mechanical pumps: absence of moving parts, low noise and vibration level, simplicity of flow rate regulation, easy maintenance and so on, making them a logical and very efficient option for molten salt and liquid metal-cooled reactors.

Electromagnetic pumps are a key enabling technology towards the development of advanced molten-salt and liquid-metal reactors which can lead to low-waste, emission-free nuclear power plants. Electromagnetic pumps allow the safe use of molten salts and liquid metals as working fluids in high temperature applications in the energy, propulsion, and industrial sectors. The operation at high temperatures also enables higher efficiency of power conversion cycle.

“I would like to thank Dr. Maidana for all of his amazing efforts to date in developing this novel technology,” said James Walker, Chief Executive Officer and Head of Reactor Development of NANO Nuclear Energy “The technology behind the SBIR Phase III program is very exciting, and complimentary to the technology behind our portable microreactor designs, and particularly ‘ODIN’. This technology is also of potential benefit to many reactor companies that utilize salt coolants. We believe we can assist all of them to reduce the size and complexity of their reactor systems by reducing the number of pumps and the associated mechanical components. This could allow for manufacturing cost reductions and simplified reactors, which assists the commercialization of the new generation of reactors. Dr. Maidana’s proven track record of collaboration with DOE entities to innovate and stimulate technological advancements aligns perfectly with NANO Nuclear’s strategic focus on fostering close partnerships with government labs and organizations. He will also be instrumental in growing our consulting business as well.”
