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.

Clinton Nuke Gets Bad Grades on Safety Drill

LCG, Aug. 29, 2001--The Nuclear Regulatory Commission said this morning that the 930 megawatt Clinton nuclear power plant operated by Exelon Nuclear Generating Co. in Illinois had failed in some emergency control room drills. The failure constituted a violation of NRC rules, the agency said.

It was not a serious violation. The NRC has four colors for violations: green, which is no violation at all, white, yellow and red, which is worst of all. Because the Clinton violations were of "low to moderate importance to safety," they were characterized as "white."

The NRC said that during an inspection in May and June of this year it found that Exelon had failed to promptly correct deficiencies in the performance of control room operators noted during drills held in late 1999 and in August of last year.

What happened was, during simulated emergencies, the operators failed to communicate information to offsite federal agencies. The NRC said 11 workers failed drill requirements in 1999 and 10 in 2000.

In February of this year, Exelon determined that it had not taken sufficient action to address the failures. The workers were retrained and retested, with all but three passing. Those three were removed from the emergency response organization.

Exelon Corp. was formed by the merger of Peco Energy Co. with Unicom Corp., the parent of Commonwealth Edison Co., and is the largest U.S. operator of nuclear power plants. Clinton was formerly operated by Illinois Power Co., which was unable to keep the plant running.

Illinois Power turned operation of the plant over to Peco in 1997. This morning, Clinton was operating at 100 percent of capacity.
