Abstract

fetched live from OpenAlex

Following our earlier metallurgical testing at SGS Lakefield, which yielded graphite as pure as could be determined by their analytical method, a sample of that same material was shown to be of nuclear-grade purity (...), said Canada Carbon CEO, Bruce Duncan. Both synthetic graphite and natural vein graphite have commonly been used in the nuclear industry in traditional reactors. This has provided the graphite industry with a niche but high value market. New generation designs feature pebble shells - nuclear fuel coated with silicon carbide, natural, synthetic and recycled graphite layers that moderate the reaction speed - which carry nuclear fuel into the reactor. These pebble-bed reactors could use significantly more graphite than today's industry and could provide future, high purity suppliers with a significant market opportunity.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
