Abstract

fetched live from OpenAlex

The Canadian supercritical water-cooled reactor (SCWR) is currently being designed by Canadian Nuclear Laboratories. It presents challenges to many scientists and engineers owing to the harsh environment in which the reactor must operate and the lack of knowledge in material’s performance under high temperature, pressure, and irradiation. In this study, 2 superalloys, A286 and Alloy 625, were tested in supercritical, high-pressure, and low-pressure steam at 625 °C for 1000 h; each represents a pressure of 29 MPa (SCW), 8 MPa (high-pressure steam), and finally 0.1 MPa (low-pressure steam). Results from this study show a higher oxidation rate, in terms of weight gain, for A286 under all conditions primarily due to its low Cr content. Alloy 625, on the other hand, exhibits much more oxidation resistance under all conditions due to the formation of protective Cr-containing surface oxide(s). Weight changes of A286 and Alloy 625 in supercritical water and low pressure steam are comparable, while high pressure steam exposure leads to considerable weight gain of A286 samples and weight loss and pitting on Alloy 625.

Teacher imitation

Not 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.
