Oklo Targets 2028 or 2029 for First Commercial Nuclear Reactor Startup

Advanced nuclear developer Oklo Inc. has adjusted the projected commercial startup window for its first Aurora powerhouse in Idaho to 2028 or 2029, building in additional lead time for testing, equipment calibration, and final plant commissioning, according to third-quarter disclosures reported by Yahoo Finance (https://www.marketbeat.com/instant-alerts/transcript-oklo-q3-earnings-call-highlights-2026-11-07/?utm_source=yahoofinance&utm_medium=yahoofinance&.tsrc=rss).

Chief Executive Officer Jake DeWitte told investors that practical engineering lessons from the company's Groves-1 test reactor showed the value of schedule buffer during assembly. DeWitte specifically pointed to post-assembly tasks such as managing electrical noise across sensitive nuclear instrumentation and ensuring integrated systems communicate reliably before commercial power delivery begins.

The Santa Clara, California-based company concluded the first nine months of 2026 with $3.1 billion in cash, cash equivalents, and marketable securities as of September 30. That reserve was anchored by $2.3 billion raised through at-the-market equity offerings during the period. Oklo posted a nine-month net loss of $123.3 million, reflecting an operating loss of $195.2 million that was partially offset by $72.4 million in net interest and dividend income. Operating cash use stood at $110.9 million, while year-to-date capital expenditures reached $280.9 million.

Management maintained its full-year guidance for 2026, anticipating $120 million to $150 million in operating cash use and $400 million to $500 million in capital spending for property, plant, and equipment.

At the Aurora-ID project site within Idaho National Laboratory, reactor-area excavation is finished, structural steel erection has commenced, and safety-related rebar installation is underway. The Department of Energy has approved the project's preliminary documented safety analysis, permitting safety-critical procurement and construction to move forward. DeWitte stated that Oklo expects to submit the full documented safety analysis closer to construction completion, likely in 2028, ahead of a readiness review and DOE startup authorization.

Alongside civil construction, Oklo is outfitting its Aurora Fuel Fabrication Facility to fabricate its inaugural reactor core using Experimental Breeder Reactor II material, targeting its first complete fuel assembly in 2027. Chief Financial Officer Craig Bealmear noted that initial power output is slated for national laboratories under DOE oversight before Oklo initiates the process of transitioning the installation to a commercial permit with the Nuclear Regulatory Commission.

Beyond Idaho, the company is advancing a planned power campus in Ohio designed for up to 1.2 gigawatts under an agreement with Meta. While DeWitte emphasized that the contract does not legally bind either party to construct the reactor, Bealmear noted it includes binding commitments, such as capital provided by Meta to reserve capacity tied to fuel procurement milestones. Bealmear projected the PJM Interconnection study process for the Ohio location will take roughly 24 months, adding that FERC's dismissal of a complaint over a withdrawn Virginia site application does not affect Ohio.

To prepare for long-term production, Oklo entered a manufacturing reservation with U.S. Forged Rings for capacity covering up to 27 Aurora modules between 2030 and 2035 at a planned facility in North Carolina, focusing on heavy components like reactor vessels, lids, and support structures. Next milestones include commissioning a fuel-recycling pilot in 2027, breaking ground on its Groves-2 facility, and completing its first contracted radioisotope delivery.
