Validation of the Iodine Chemistry Code Iode 4.2 - Interpretation of PHEBUS/RTF Tests
Bibliographic record
Abstract
Six RTF (Radioiodine Test Facility) tests were performed at AECL/Whiteshell, Canada, in the framework of the COG (Candu Owners Group) - PHEBUS FP agreement with the objective of providing data for iodine behaviour under conditions relevant to the integral PHEBUS tests. RTF tests results constitute a very important database both for helping the interpretation of PHEBUS tests and for the validation of iodine chemistry codes such as IODE. The first part of this report provides an overview of the PHEBUS/RTF tests main results. The second part of the report is devoted to the validation work performed for the code IODE, version 4.2 included in ESCADRE modl.2. Tests performed with silver mesh (RTF3 and RTF6) were used for the validation of the newly developed model of Ag/I reactions in the sump.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
