Abstract
For safe and efficient operation of the Darlington Nuclear Generating Station’s Tritium Removal Facility (DTRF), it is necessary to track the amount of operational tritium inventory within the DTRF’s process systems. Previous methodology that tracks operational tritium inventory is based on performing a tritium mass balance and does not provide an instantaneous way to determine inventory in the DTRF. The estimate of operational tritium inventory using this method is susceptible to increasing cumulative error of approximately ±2.6% per day as the DTRF continues to operate. Current methodology attempts to compensate for this cumulative error by assuming a constant value for operational tritium inventory whenever Mass 5 is detected by mass spectroscopy of tritium drawoff gas. However, this assumption is flawed and introduces significant error to the estimation of operational tritium inventory. A new method based on temperature of the cryogenic high tritium distillation (HTD) process is proposed which can track operational tritium inventory in a more instantaneous fashion and provides a result with a constant error of ±14% that does not increase over time.

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
