California Nanotechnologies Corp. (TSXV: CNO) (OTCID: CANOF) announced on September 14, 2026, that it has received its single largest purchase order in company history from an existing U.S.-based advanced nuclear energy customer. The order covers boron-carbide (B₄C) reactor control components intended for use in a small modular reactor (SMR) program. The announcement marks a meaningful step in Cal Nano's stated strategy to transition from advanced materials development into larger-scale production within the nuclear energy sector.

Key Points

  • California Nanotechnologies Corp. (TSXV: CNO | OTCID: CANOF) announced its largest-ever purchase order
  • The order is for boron-carbide reactor control components destined for a single SMR program from a leading U.S.-based nuclear energy customer
  • Full delivery is expected by the end of the company's current fiscal year; the financial value of the order was not disclosed in the announcement
  • The order follows prior B₄C component deliveries to a separate customer reactor that recently achieved criticality

Cal Nano's Boron-Carbide Components and Their Role in the SMR Program

The purchase order covers boron-carbide reactor control components, which function in neutron-absorbing control and shielding applications inside fission reactors. Cal Nano produces these components using specialised capabilities that include powder processing, spark plasma sintering, cryomilling, densification, machining, and quality assurance — processes that the company states require significant technical expertise. The announcement notes that the components are expected to be used within a single SMR program, representing an increase in scope compared with prior orders placed by the same customer.

Record Order Builds on Prior Nuclear Customer Milestone

Cal Nano noted that this latest order follows previous boron-carbide component deliveries made to a different customer's reactor program, which recently achieved criticality — a significant operational milestone in nuclear reactor development indicating a self-sustaining chain reaction. The company's CEO, Eric Eyerman, stated in the release that the award demonstrates Cal Nano's ability to transition development programs into a larger-scale production mandate, and cited the company's scalable domestic manufacturing capabilities as a strategic differentiator for next-generation reactor developers.
