Abstract
Existing Canadian Nuclear Power Plants (NPPs) are aging, with 19 active reactors being in operation for 35 to 50 years. To ensure their leak tightness, concrete containment structures of NPPs shall be regularly leakage-rate tested in accordance with Integrated Leakage Rate Test (ILRT) requirements as detailed in CSA N287.7 and CNSC regulatory documents.<br> Concrete containment structures shall be subjected to ILRTs to ensure their leak tightness, either every 6 years or conforming to a performance-based test interval agreed upon between the licensee and the Authority Having Jurisdiction (AHJ), i.e. the CNSC. To establish a performance-based ILRT interval option, in addition to inspection, testing, and aging management requirements, demonstration shall be made to the AHJ that the leakage-rate trends, maintained from commissioning to the most recent outage ILRT, are stable over at least the two most recent (post-commissioning) outage tests. Stable is defined in CSA N287.7-17 as no statistically significant increase that would cause the acceptance leakage limit to be exceeded if it changed in a linear fashion over the next test interval.<br> The stability requirements mentioned above may be subject to interpretation. This paper discusses various options for trending leakage-rate test results and recommends a multi-step approach.

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
