NRC Approves Oklo's Principal Design Criteria Topical Report for Aurora Powerhouse

LCG, May 6, 2026--Oklo Inc. ("Oklo"), an advanced nuclear technology company, announced today that the U.S. Nuclear Regulatory Commission (NRC) has approved the Principal Design Criteria (PDC) topical report for the Aurora-INL (Idaho National Laboratory) nuclear small modular reactor (SMR), which is currently under construction in Idaho. The PDC topical report establishes a regulatory framework that defines the fundamental safety, reliability, and performance requirements to guide future reactor licensing and design activities, and the approved report should simplify future applications and reduce the need to re-review established material.

Mirant Says 600 Megawatts Face Emissions Shutdown

LCG, July 23, 2001Mirant Corp., which operates the 2,022 megawatt Pittsburg power plant it purchased from Pacific Gas & Electric Co., warned again Friday that emissions regulations may force it to shut down four units having a combined capacity of 600 megawatts.

The result, combined with the opening two weeks ago of Calpine Corp.'s new 555 megawatt Pittsburg plant, would be a net loss to the state of 45 megawatts of much-needed generation in a city that regards power plants highly.

Mirant said it had told the state in April that it would be forced to cease operating parts of the Pittsburg plant if it could not secure emissions waivers, but the warning apparently went unnoticed by state officials.

"That's pretty big news if they're going to shut it down indefinitely," said Stephanie McCorkle, a spokeswoman with the California Independent System Operator. "I haven't heard this. Obviously, we wouldn't want to see any megawatts go away."

Even Steve Maviglio, the spokesman for Gov. Gray Davis, was surprised by the news. "It's significant, no doubt about it," he said. "We're going after every megawatt we can get. As a broad policy, as much power as we can keep on-line is beneficial until we can get new plants up and running."

Mirant had planned to tear out some of the units at Pittsburg and replace them with 530 megawatts of new generation, but tabled those plans earlier this year, citing California's "hostile" business climate as exemplified by the governor's vilification of independent power producers.

Now, the company has been ordered to cut nearly in half the average hourly nitrogen oxide emissions at Pittsburg and two other plants it owns in the San Francisco Bay Area. Faced with the massive investment in new emissions controls, coupled with the high operating costs of the old units, the company says it has little choice other than to shut down some generation.

"We're very serious about shutting them down" unless the company gets permission to exceed the emission limits, said Mark Gouveia, vice president and chief operating officer of Mirant's California division. "We're not going to violate the law to run them."
