NANO Nuclear Advances KRONOS With Baker Hughes, Adds Enveniam To Fuel Efforts

Three weeks after we noted that NANO Nuclear Energy's vertical-integration strategy was beginning to look more like a physical fuel cycle than a corporate slide deck, the company has delivered a pair of updates spanning both ends of the nuclear value chain.

NANO’s announcement from Thursday details ongoing progress for the design of a circulation pump for cooling their KRONOS reactor, and Friday's announcement describes the multi-prong agreement with a new engineering firm for developing their nuclear fuels business segment.

Development of the primary helium circulator was moved from preliminary engineering to detailed design. Howden, a Baker Hughes subsidiary following the acquisition of Chart Industries, is “building upon the reactor performance requirements established by NANO Nuclear.”

The helium circulator is one of the most critical components of high-temperature gas-cooled reactors like NANO's KRONOS design. It moves helium coolant through the reactor to transfer heat from the core and out to the secondary system.

Howden has established a “mature technical foundation” which allows for further optimization in manufacturing planning.

Jay Yu, Founder and Chairman of NANO Nuclear Energy, noted:

"each engineering milestone strengthens the industrial ecosystem supporting KRONOS while further positioning the program for future first-of-a-kind deployment and long-term commercial success."

The day after announcing progress with the circulator, NANO released a statement detailing a new agreement with Enveniam.

The MOU establishes a collaboration between the two companies addressing a wide range of operations across the nuclear value chain. The press release points to six principle workstreams under the combined effort:

• Nuclear fuel transportation
• Conversion and deconversion
• Microreactor commercialization
• Advanced manufacturing
• Domestic fuel supply chain
• Commercial energy markets

James Walker, Chief Executive Officer of NANO Nuclear Energy, highlights:

"Enveniam's capabilities closely align with our expertise and business plans across these critical workflows. We believe this collaboration can help us evaluate projects more efficiently, identify execution risks earlier and build stronger delivery plans as opportunities advance toward definitive agreements."

Most notably, this new work between NANO and Enveniam follows the announcement last year that Enveniam will be serving as Lead Project Integrator for LIS Technologies.

There, Enveniam will lead “the design, development, and construction of the LIST laser-based uranium enrichment facility.”

LIS Technologies and NANO Nuclear are working together to develop a vertically integrated fuel chain, with LIS fulfilling the enrichment stage. NANO is working on multiple other stages of the fuel chain, to include conversion and deconversion, fuel fabrication, and fuel transportation.
