Tailings System Safety Review for the Quirke Tailings Management Area in Elliot Lake
Bibliographic record
Abstract
Rio Algom Limited’s Quirke Tailings Management Area in Elliot Lake contains 46 million tonnes of low-level radioactive, acid-generating tailings. Rehabilitation of the tailings area began soon after mining ceased in 1990. Since 1995, the 192 ha tailings area has been successfully flooded under a series of terraced cells. This provides a permanent water cover over the tailings to inhibit acid generation. The facility has been designed to safely contain the tailings for the long term with on-going maintenance provided to ensure that the containment structures continue to function as intended in accordance with the decommissioning plan. This paper describes a comprehensive tailings safety review for the facility along with the care, maintenance and surveillance program and discusses potential consequences associated with extreme disruptive events such as floods and earthquakes. The tailings safety review was broad based and focused on the performance of the tailings system as well as the individual structures. The intent of the review was to confirm that the facility had been designed, constructed and managed in accordance with acceptable standards. Where applicable, the review was based on Dam Safety Guidelines proposed by the Canadian Dam Association.

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.
