Maximum Credible Accident Methodology Topical Report Performance-Based Licensing Methodology Topical Report Oklo Inc. (Oklo) is submitting to the U.S. Nuclear Regulatory Commission (NRC) a Maximum Credible Accident Methodology Topical Report and Performance-Based Licensing Methodology Topical Report, as Enclosures 1 and 2 to this letter. These topical reports represent specific methodologies used to develop the licensing basis for Oklos Aurora at Idaho National Laboratory combined license application. These methodologies are being submitted, in part, to support alignment and mutual understanding between Oklo and NRC staff on key safety and design aspects of the licensing basis.

In addition to the role these topical reports provide for progressing the Aurora at Idaho National Laboratory combined license application review, they can also play a key role in the future licensing of advanced nuclear reactors. Congress recognized the significance of nuclear powers capabilities of mitigating the impacts of climate change by enacting the Nuclear Energy Innovation and Modernization Act (NEIMA) in 20191. NEIMA directs the NRC to develop a technology-inclusive licensing process for advanced nuclear reactors, enabling their timely and efficient deployment such that they can effectively contribute to the nations decarbonization efforts. Oklos licensing approaches support this exigent need by offering a set of performance-based licensing methodologies that are both technology-inclusive, but also enables both greater efficiency and stronger safety controls. It is therefore imperative that the NRC consider such approaches as it pursues regulatory framework development for advanced nuclear reactors.

It is in the public interest for the NRC to license plants with improved safety characteristics, in particular passive functions and inherent features. Further, it is in the public interest to ensure that regulatory controls are more efficiently and effectively applied directly to these functions and features. A better regulatory framework both ensures designs that are safe and facilities the commercialization of advanced nuclear power.

In recognition of the additional role of these topical reports, on June 17, 2021, Oklo also submitted a fee waiver request (ML21168A377) for the review of these topical reports, which specifically details the basis of the request. Oklo looks forward to engaging with NRC staff to support a decision on this request.
