Oklo announced last week that it hopes to expand development and global deployment of its advanced nuclear technology through a new partnership with Korea Hydro & Nuclear Power.

The memorandum of understanding includes plans for the companies to advance standard design development and global deployment of Oklo’s planned Aurora Powerhouse, a microreactor that would generate 15 MW and be scalable to 50 MWe. Oklo said each unit can operate for 10 years or longer before refueling.

Oklo and KHNP plan to cooperate on early-stage project development, including manufacturability assessments and planning of major equipment, supply chain development for balance-of-plant systems, and constructability assessments and planning.

Quotable: “We’ve recently completed site characterization borehole drilling for our first commercial Powerhouse and are preparing for construction, with commercialization as a top priority,” said Jacob DeWitte, cofounder and CEO of Oklo. “Partnering with KHNP, one of the most accomplished nuclear builders in the world, who [has] been building nuclear power plants continuously since 1971, offers meaningful opportunities to align on key execution factors such as manufacturability, constructability, and supply chain development. Their experience in delivering projects at scale can complement our efforts and help us move more efficiently toward commercialization and the ability to build future powerhouses faster.”

KHNP CEO Ju-ho Whang said, “KHNP is focusing on developing its innovative domestic advanced nuclear technology, the i-SMR, to achieve world-class competitiveness. In addition to enhancing safety, successful entry into the advanced nuclear market requires cooperation with leading technology firms. By combining the strengths of KHNP and Oklo, we expect to create strong synergy in the design, construction, and operation of advanced nuclear technology.”

Background: Oklo is currently working on preapplication requirements with the U.S. Nuclear Regulatory Commission and intends to submit its formal combined license application later this year, which would enable both the construction and operating licenses to be granted in tandem.

Oklo also plans to file follow-on applications to support its growing order pipeline, which the company said exceeds 14 GW. It is developing advanced fuel recycling technologies in collaboration with the U.S. Department of Energy and the U.S. national laboratories.

Oklo began trading on the New York Stock Exchange a year ago after partnering with AltC Acquisition Corp., formerly run by billionaire Sam Altman, who served on Oklo’s
