(GLOBE NEWSWIRE) --
NANO Nuclear Energy Inc.
(NASDAQ: NNE) ("NANO" or “the Company"),
a leading advanced nuclear micro modular reactor and technology company developing microreactors, nuclear fuel cycle capabilities and nuclear transportation solutions, today announced that it has entered into a Engineering Services Master Agreement (ESMA) with the
U.S
. subsidiary of
IMPSA
, one of
Argentina's
leading engineering and heavy-manufacturing companies, to support the engineering, design-for-manufacture and potential future fabrication of critical components for NANO Nuclear’s
KRONOS MMR
™
Energy System.
The three-year agreement establishes a framework for NANO Nuclear to utilize
IMPSA's
extensive experience in nuclear pressure vessels, ASME Section III manufacturing, welding, non-destructive examination, quality assurance and heavy-component fabrication as the
KRONOS MMR
™
design progresses toward manufacturing readiness.
The reactor pressure vessel is specifically identified as a principal reactor-component under evaluation by
IMPSA
. The parties have separately identified reactor cavity cooling systems, spent-fuel storage systems and additional reactor and transportation components as additional areas of potential collaboration.
Initial KRONOS MMR
™
Engineering and Manufacturability Program
Under the ESMA, NANO and
IMPSA
are beginning with a dedicated
KRONOS MMR
™
Design Review and Assessment –
Engineering Consulting
and Manufacturability Feasibility Study. The initial program provides for an estimated six-month period, supported by a retainer.
IMPSA's
work is expected to include an independent review of
KRONOS MMR
™
components against applicable ASME Boiler and Pressure Vessel Code Section III requirements and the application of
IMPSA's
prior experience engineering and fabricating nuclear pressure vessels and other nuclear components.
The program aims to incorporate manufacturing expertise into the
KRONOS MMR
™
design process at an early stage, allowing the companies to identify potential fabrication constraints, inspection limitations, accessibility issues, supply-chain risks and potential design improvements ahead of future manufacturing. As required by NANO, the work may also extend to detailed engineering and fabrication drawings, code-compliant calculations, 3D models and other engineering deliverables.

"
IMPSA
has developed sophisticated nuclear engineering and manufacturing capabilities over many decades, and we see an opportunity to connect that expertise with the next generation of advanced nuclear projects,"
said
Jay Yu
, Founder and Chairman of
NANO Nuclear Energy
.
"Our objective is to build NANO Nuclear with the capabilities needed to commercialize nuclear technology: reactor engineering, manufacturing, fuel, transportation and project execution. Our relationship with
IMPSA
can strengthen several of those areas at the same time while establishing an important industrial relationship between
the United States
and
Argentina
."
"Advanced reactors have to move from drawings and calculations to modular components that can be manufactured repeatedly, inspected, qualified and assembled,"
said
James Walker
, Chief Executive Officer of
NANO Energy
. "
IMPSA
brings more than four decades of nuclear engineering and manufacturing experience and particularly valuable expertise in nuclear pressure vessels and ASME Section III fabrication. Having that manufacturing knowledge applied to KRONOS at this stage is expected to identify constraints earlier, strengthen the design-for-manufacture process and build a much more direct pathway toward future component production."
The non-exclusive ESMA describes
IMPSA
as one of the few companies in
Latin America
certified with ASME N and
ASME III N
stamps, providing capabilities for the engineering and construction of Class 1 heavy nuclear components.
"This alliance represents a strategic opportunity for
IMPSA
and for the Argentine nuclear industry,"
said Jorge Salcedo Hernández, President of
IMPSA
. "With decades of experience manufacturing pressure vessels under ASME N-Stamp certification,
IMPSA
has established itself as one of the few suppliers capable of assessing the manufacturability of nuclear components at an early stage. Our goal is to enable NANO Nuclear to accelerate the
KRONOS MMR
™
manufacturing process, advancing toward safer and more efficient nuclear systems."
Future component fabrication, regional projects or other commercial activities beyond the initial engineering services will remain subject to the results of the engineering work, applicable regulatory requirements and, where required, additional work orders or definitive agreements between the relevant parties.
