Nano Nuclear Energy Inc. (NASDAQ:NNE) shares gained 3.7% in premarket trading Wednesday after the company reported successful high-heat trials of its Annular Linear Induction Pump (ALIP), reaching operating temperatures of up to 350°C.
The evaluation, carried out at Nano Nuclear’s demonstration site in Westchester County, New York, confirmed that the upgraded coil ruggedization and insulation systems functioned as intended. The ALIP platform serves as a thermal management solution for next-generation reactors that rely on high-temperature coolants such as molten salts and liquid metals.
CEO James Walker said the latest round of testing “validates the ALIP system’s core design and durability, marking an important step toward the eventual commercialization of this proprietary technology.” He noted that the outcomes also highlight the firm’s progress in its effort to “bring advanced technology from the design room to real world operations.”
These results build on earlier closed-loop flow testing completed earlier in the year, after which Nano Nuclear introduced design tweaks aimed at boosting magnetic field strength and enhancing overall performance. The company also confirmed manufacturing precision and electromagnetic quality-control processes at the same facility.
Looking ahead, Nano Nuclear plans to market ALIP as a zero-maintenance alternative to traditional mechanical pumps used for handling molten metals—targeting both ground-based reactor systems and potential in-space applications. The firm expects to advance into the next phase of commercialization in the near term.
