Missed Nvidia in 2009? This Rare Signal Is Flashing Again. In 2009, a "Double Down" signal flashed for a little-known chipmaker called Nvidia. For the first time in years, that same "Total Conviction" signal is flashing for a company 1/100th the size of Nvidia. Continue »

Oklo announced today that the U.S. Department of Energy's (DOE) Idaho Operations Office has approved the company's Preliminary Documented Safety Analysis (PDSA) for its Aurora powerhouse at Idaho National Laboratory (INL) under DOE's Reactor Pilot Program.

According to Jacob DeWitte, co-founder and CEO of Oklo, "This approval represents an important milestone for Aurora-INL and helps establish a foundation for future Aurora deployments."

The Aurora-INL is the first of the company's planned advanced nuclear reactor facilities. With the DOE approval of the PDSA, Oklo is one step closer to securing the Documented Safety Analysis, the final safety document that the DOE requires.

With the company taking a major step closer to securing the necessary approvals from the DOE for Aurora-INL, it's unsurprising that the stock soared today. While this development reduces some risk around Oklo stock, it should still be considered for those comfortable with more speculative investments.

Even if the company secures all licenses, there's no guarantee its nuclear energy ambitions will lead to profitability. Fortunately, for those seeking exposure to the nuclear energy renaissance underway, there are nuclear energy ETFs that offer more conservative investment options.
