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.

Arizona Corporation Commission Rejects Utilities' Integrated Resource Plans

LCG, March 22, 2018--The Arizona Corporation Commission last week rejected the Integrated Resource Plans (IRPs) filed by Tucson Electric Power Co. (TEP), sister utility UniSource Energy Services (UNS) and Arizona Public Service Co. (APS) and has ordered them to develop plans that reduce their dependence upon natural gas and new, gas-fired power plants. The Commission prefers greater reliance on renewable energy and storage.

The Commissioners voted 3-2 to reject the resource plans. However, the Commission unanimously approved the final order to reject the plans. The Commission did not accept a Commission Staff recommendation to approve that the resource plans. The Commission placed a moratorium through 2018 on the purchase of any natural-gas power plant with a generating capacity greater than or equal to 150 MW. Furthermore, the Commission approved a new process to revamp the rules.

The three electric utilities are required to file IRPs every two years. The IRPs include 15-year forecasts of energy demand and supply resources to meet that load, including a three-year action plan.

The Commission adopted a new proposal that requires the utilities to prepare IRPs that include at least one supply portfolio where the addition of fossil fuel resources does not exceed 20 percent of all resource additions. Furthermore, a proposal was supported to add scenarios including a least one gigawatt of energy-storage capacity, and at least 50 percent "clean energy resources," including biomass energy and energy efficiency measures.

An APS spokesperson stated, "Our plan keeps Arizona on course for a cleaner energy future, so we respectfully disagree with the Commission's decision not to acknowledge any IRPs (integrated resource plans) even after Commission Staff determined they were complete and responsive to the filing requirements. We all agree on the goal of cleaner energy, and this decision doesn't change that - or how we will meet our customers' energy needs in the near-term."
