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.
