Abstract
Analyses of the safety system response to postulated loss-of-coolant-accident (LOCA) events were performed using the SCTRAN safety analysis computer code for the Canadian supercritical water-cooled reactor (SCWR) concept. These analyses covered both the cold-leg break and hot-leg break LOCA scenarios. All relevant passive safety systems, such as automatic depressurization system, accumulator, and gravity-driven cooling system, were included in the simulation. The simulation for the cold-leg break LOCA showed 2 cladding temperature peaks over the duration of 100 seconds. Over the range of break sizes (i.e., 25%, 50%, and 100%) investigated in this study, the first peak cladding temperature predicted for the 25% break size is higher than that for the 100% break size, but the second peak cladding temperature predicted for the 25% break size is lower than that for the 100% break size. Simulations of the hot-leg break LOCA have resulted in only 1 cladding temperature peak, which was not significantly affected ...

Full frame distilled prediction
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
