OKLO INC Non-Applicabilities &
Requested Exemptions for the Aurora-INL
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 Oklo develops clean energy generation sources with advanced fission to mitigate the social and environmental impacts of pollution as well as energy poverty.
Aurora Powerhouse The Aurora 1-2 MWe output depending on use case 20 years between refueling Advanced fission battery with solar Can utilize used material (waste)
Current large light water reactors Aurora Power output (MWth) 1600-4400 <5 Refueling cycle (years) 1.5-2 None Radionuclide inventory 100-150 <5 (metric tons)
System pressure (atm) 150 Near atmospheric Hydrogen explosion Yes No risk Cooling Loop with low thermal inertia Passive heat pipes Electric power Relies on offsite power or emergency No safety-related electric dependence diesel generation power dependence Negative reactivity Yes Yes coefficient
Methodology
Background
Atomic Energy Act NRC regulations Regulations generally have two characteristics:
- 1. They contain assumptions about the facility
- 2. They evoke that adequate protection is assured, in part, through compliance
Background Non-Applicability Atomic Energy Act NRC regulations Regulations generally have two characteristics:
- 1. They contain assumptions about the facility
- 2. They evoke that adequate protection is assured, in part, through compliance
Background Exemption Atomic Energy Act NRC regulations Regulations generally have two characteristics:
