Abstract

fetched live from OpenAlex

This paper summarizes the experimental tritium permeation rates of various barrier materials considered for fusion and Generation IV applications in the temperature range of 600–1000 °C.Determination of accurate permeation rates is important to design and engineer safe systems that are used in fusion reactors and in very high temperature reactors (VHTRs) of Generation IV. For fusion reactors, tritium permeation in the blanket region and fuel reprocessing area can contribute to loss of fusion fuel, environmental emissions, and worker dose. For VHTRs, tritium permeation in the main core and the intermediate heat exchangers can result in tritium contamination of the hydrogen production process.Testing is performed in a sample configuration that closely resembles the geometry of a tube-in-tube heat exchanger and the permeation rates are measured at high temperatures (500–1000 °C) using an induction heater. A permeation test is conducted with a thin-walled test strip welded in between stainless steel 304L heav...

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.
