Non-Applicabilities &
Requested Exemptions for the Aurora-INL OKLO INC
Oklo develops clean energy generation sources with advanced fission to mitigate the social and environmental impacts of pollution as well as energy poverty.
About us Raised the first-ever, modern, venture-led, series A for a fission company Granted an INL site use permit from Department of Energy Selected to demonstrate recycle of spent fuel at Idaho National Laboratory Became the first advanced fission company in the country to have a license application accepted by the U.S. Nuclear Regulatory Commission
Aurora Powerhouse
1-2 MWe output depending on use case 20 years between refueling Advanced fission battery with solar Can utilize used material (waste)
The Aurora
Current large light water reactors Aurora Power output (MWth) 1600-4400
< 5 Refueling cycle (years) 1.5-2 None Radionuclide inventory (metric tons) 100-150
< 5 System pressure (atm) 150 Near atmospheric Hydrogen explosion risk Yes No Cooling Loop with low thermal inertia Passive heat pipes Electric power dependence Relies on offsite power or emergency diesel generation No safety-related electric power dependence Negative reactivity coefficient Yes Yes
