Fusion42 · 21 September 2026 · Fusion42 review

Deep Fission and Youngquist Brothers have partnered to test large-diameter borehole drilling techniques for deploying underground small modular reactors, targeting commercial deployment by 2027. This collaboration involved a prototype canister lowered into a borehole and leverages decades of Youngquist's drilling expertise for deep commercial boreholes.

This Wire brief sits within Fusion42's coverage of Clean Energy.

◆ ◆ The Wire takeaway

You can now pitch services or tech that improve borehole installation or retrieval speed for underground nuclear reactors. The door opens quickly to play into early SMR deployments where drill tech becomes a bottleneck.
