Crystalline texture in Zr-based alloys tubes
Bibliographic record
Abstract
Pressure tubes are the most important Zr-base components in the core of CANDU nuclear power reactors. The most important mechanisms defining the service life of pressure tubes are: irradiationenhanced coming with deformation, and the delayed hydride cracking. Both processes are determined by a few metallurgical parameters which must be exhaustively controlled: microstructure, dislocation density and texture [1], [2]. Argentina has one CANDU power plant in operation since 1982 (CNE), which is now close to ending its service life. A refurbishment project is underway which will include the replacement of existing fuel channels, composed by Zr-2.5%Nb pressure tubes and Zircaloy2/4 calandria tubes. CNEA is developing a new manufacturing route for Zr-2.5%Nb pressure tubes, using a cold rolling pilger type machine instead of the cold drawing process currently performed in Canada. The new process will be performed at the Planta Piloto de fabricacin de aleaciones especiales (PPFAE,CNEA).

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.
