Abstract
Abstract As the deployment of small modular nuclear reactors (SMR) in Canada approaches, waste management considerations become increasingly critical. This study investigates the potential degradation mechanisms during the initial dry storage phase of TRISO fuel waste storage containers. Specifically, this research explores the possible galvanic corrosion of the graphite outer casing of TRi-structural ISOtropic (TRISO) fuel and the carbon steel storage material, resulting from the ingress of air/water. Proximity to water sources can exacerbate corrosion, particularly due to the presence of Cl ions. Additionally, water radiolysis may lead to the formation of hydrogen peroxide and nitric acid, further influencing corrosion rates. This study examines the galvanic coupling between graphite and ferrous alloys under varying concentrations of NaCl to identify concentrations that may significantly impact material integrity. Electrochemical testing along with immersion testing were employed to determine the extent of galvanic coupling at varying NaCl concentrations.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
