NANO Nuclear and Howden push the KRONOS MMR helium circulator into detailed design, moving a core piece of the microreactor’s cooling system closer to reality
Ever since the United States became the leading nuclear energy-producing country in the world, it has maintained its position by executing groundbreaking projects that enhance its overall capacity. U.S. based companies are aware of the position that the nation occupies and are actively playing their part in ensuring that it continues to be recognized as a leader. Additionally, companies have greater freedom to experiment through the use of technology and reliance on technological innovation in attempts to discover the most efficient ways of energy generation. On that note, NANO Nuclear and Howden recently pushed the KRONOS MMR helium circulator into detailed design, moving a core piece of the microreactor’s cooling system closer to reality.
Unpacking NANO Nuclear Energy’s contributions to the nuclear energy sector
NANO Nuclear Energy’s main focus is developing smaller, simpler, and safer advanced nuclear microreactors for terrestrial, remote, and space applications. It is also well known for operating across microreactor technology development, nuclear fuel fabrication, transportation, and consulting.
Among the company’s contributions is the KRONOS MMR, which is a stationary modular microreactor system that serves as the company’s lead technology. Secondly, there is ZEUS, which is a portable, solid-core battery reactor designed for on-demand power. There are very high hopes that the nuclear sector will be integral to the United States’ ability to meet its overall clean energy targets.

In another display of the company’s commitment to the nuclear sector, a recent press release from NANO Nuclear Energy revealed that the company is making continued progress toward the development of the primary helium circulator for its proprietary KRONOS MMRTM Energy System under its engineering collaboration with Howden, a Baker Hughes business.
Nuclear energy projects are often too expensive for a single entity to manage on its own, which explains the increased number of partnerships that have materialized in 2026. The helium circulator is seen as an essential mechanical subsystem within the KRONOS MMRTM Energy System. It is responsible for circulating helium coolant throughout the reactor to efficiently transfer heat generated within the reactor core.
The circulator is important in overall plant efficiency, thermal performance, and long-term operational reliability. Industry experts believe that it is going to be a constant feature of the nuclear sector heading into the future, with more sophisticated projects. Howden, a provider of air and gas handling products that is now part of Baker Hughes, is leading the engineering of the helium circulator, with the collaborating companies complementing each other effectively.
Breaking down the role of both companies in the KRONOS MMR project
Howden is applying its expertise from decades of experience in helium turbomachinery and high-temperature gas-cooled reactor technology to develop a solution specifically meant for the performance requirements of the KRONOS MMRTM Energy System.
The progress that has been made from preliminary engineering into the detailed design phase represents a massive milestone for the companies. Howden has been able to build on the reactor performance requirements that were previously established by NANO Nuclear and has since complemented key engineering evaluations, developed three-dimensional design models, performed engineering analyses, and conducted formal design reviews with NANO’s engineering team.

The company has dedicated a lot of time and effort to the captivating project. After the company’s recent success, James Walker, Chief Executive Officer of NANO Nuclear Energy, stated the following:
“Progressing the primary helium circulator into detailed design represents another important milestone in the continued development of the KRONOS MMR™ Energy System. Advancement of the circulator design strengthens the technical foundation of the overall reactor program and demonstrates the disciplined engineering execution essential for successful commercialization.”
NANO Nuclear Energy is one of the most recognizable nuclear energy companies in the world, as it has played a massive role in shaping the United States’ current landscape. The company is a publicly traded U.S. advanced nuclear technology company that is focused on portable and stationary microreactors.
