Risk-Informed Mechanistic Source Term Calculations for a Compact Fast Reactor, Oklo Inc.

The objective of this project was to focus on the coupling of three high fidelity analysis codes for detailed core analysis, an analysis of the Oklo reactor design to assesses the potential for radionuclide release to the environment during accident scenarios, and an assessment and provision of relevant metal fuel data through inspection of post-irradiation examination data from past metal fuel testing. This project had two additional objectives, the experimental characterization of liquid metal heat pipe performance, failure behavior, and phenomena and the testing of generic heat pipes beyond their design limits, providing original data and insights.

Legacy Metal Fuel Data Exploration for Commercial Scale-up, Oklo Inc.

Oklo Inc. (Oklo) partnered with Argonne National Laboratory (ANL) and Idaho National Laboratory (INL) to accelerate the fuel manufacturing process to support Oklo’s path to commercialization. The project involved compiling and assessing information about legacy metal fuel data and fabrication from EBR-II, the liquid-metalcooled fast reactor that operated for 30 years at INL.
