IAEA Approves SAIHEAT as Official SMR Vendor
SINGAPORE, June 02, 2025 (GLOBE NEWSWIRE) -- SAIHEAT Limited (“SAIHEAT” or the “Company”) (NASDAQ: SAIH, SAITW), is pleased to announce that the International Atomic Energy Agency (“IAEA”) has officially approved SAIHEAT as a vendor of small modular reactors (“SMRs”), endorsing the conceptual design and reactor description submitted by the Company.
This approval marks a significant advancement in SAIHEAT’s SMRs business line and is based on an innovative reactor plant design rooted in decades of proven experience with transportable nuclear power solutions. The approved SMRs concept leverages established technologies and globally recognized materials to meet modern safety standards, regulatory requirements, and efficiency expectations.
The SMRs plant features an integral reactor design, ensuring compactness, reduced radiation exposure, and enhanced safety through minimized pressurized coolant interfaces. The unit is intended for deployment in ground-based SMRs power stations, integrating core systems such as the reactor, steam turbine generator, and automated control and protection systems.
This concept uniquely positions SAIHEAT to power next-generation digital infrastructure — particularly data centers — with clean, reliable, and scalable nuclear energy. The reactor core’s design and material composition have been optimized for long campaign cycles, while all primary circuit components are housed in a sealed safety containment to localize potential radioactive releases.
In addition, the SMRs plant is equipped with robust safety systems, including:
- Emergency Cooldown System (ECS)
- Emergency Reactor Cooling (ERC)
- Absorber input for emergency shutdown
- Overpressure prevention systems
- Multi-layer containment and protective structures
- Dedicated cooling systems for equipment safety
This recognition by the IAEA paves the way for future global deployment of SAIHEAT’s SMRs technology and reinforces the company’s commitment to sustainable, secure, and innovative nuclear power solutions.
