Under the initiative, CNL will qualify existing experimental data and benchmark computational models used to predict heat pipe performance at temperatures above 900 degrees Celsius.

The qualified experimental data provided by CNL will expand the validation database for NuCube’s computational model and is expected to play an important role in supporting the licensing pathway for NuCube’s technology.

"Our collaboration with Canadian Nuclear Laboratories represents an important opportunity to further validate NuCube Energy’s heat pipe technology and advance the refinement of our high-temperature reactor design," said Cristian Rabiti, CEO of NuCube Energy. "We are pleased to work together on these important efforts as we continue pursuing our goal of delivering clean, carbon-free power to customers worldwide."

NuCube’s advanced reactor development efforts are critical to providing safe, secure, clean, and cost-effective means to meet market demand.

"A key part of CNL's mandate is helping enable innovation in Canada's nuclear industry," said Monica Regalbuto, Vice-President, Science & Technology at Canadian Nuclear Laboratories. "By making our research infrastructure, expertise, and scientific capabilities available, we help technology developers address important technical questions and generate the data needed to advance their work. This collaboration reflects CNL's role as Canada's national laboratory and our commitment to supporting a strong and innovative nuclear sector."

On June 25, 2026, NuCube announced that it has entered into a business combination agreement with Launch Two Acquisition Corp. (NASDAQ:LPBB) ("Launch Two"). Upon closing, the combined company is expected to be listed on Nasdaq or NYSE, subject to satisfaction of listing requirements and other conditions to closing the business combination.
