Deep Fission: Deployment Not A Criticality Experiment

Deep Fission is not primarily trying to reinvent reactor physics; it is attempting to commercialize a borehole deployment model using conventional PWR technology, standard LEU fuel, and established drilling methods.

The post-IPO weakness appears driven more by technical selling, limited market awareness, and development-stage skepticism than by a material change in the company’s commercial roadmap.

Deep Fission’s DOE Reactor Pilot Program path is differentiated because the company is advancing the reactor configuration that management intends to commercialize, not merely pursuing a standalone criticality experiment.

The company’s 18.5 GW LOI pipeline and large valuation discount versus advanced nuclear peers create meaningful upside potential, but only if technical, regulatory, commercial, and financing milestones are met.

The most important near-term catalyst is the planned 2,000–2,500 foot proof-of-concept borehole, which is intended to test drilling, emplacement, retrieval, and field deployment assumptions.

Since my last article on Deep Fission , the company has completed its NASDAQ IPO, and the stock has traded poorly. My read is that the weakness has less to do with a changed technical thesis and This article was written by Prati Management 4.75K Followers Follow Richard Prati is an independent investor and former Wall Street technology research executive with nearly four decades of experience across semiconductors, infrastructure, networking, capital cycles, and technology infrastructure transitions.
