THE ANNEALING OF IRRADIATION DAMAGE IN ZIRCALOY-2 AND THE EFFECT OF HIGH TEMPERATURE IRRADIATION ON THE TENSILE PROPERTIES OF ZIRCALOY-2
Bibliographic record
Abstract
Tensile specimens of annealed and cold-worked Zircaloy2 were irradiated at 380 tained C with 9.5 x 10//sup 19/ n/cm/sup 2/ and tested at room temperature. Annealed samples of Zircaloy-2, irradiaied at 280 tained C with 7.7 x 10/sup 19/ n/cm/sup 2/ and at 50 tained C with 9.1 x 10/sup 19/ n/cm/sup 2/, were given isothermal and isochronal post-irradiation anneals and then tested at room temperature. The annealed and cold-worked specimens irradiated at 380 tained C exhibited only a small amount of radiation damage in contrast to specimens irradiated at or below 280 tained C which experienced considerable irradiation hardening. Results on the cold-worked material irradiated at 380 tained C indicated that the amount of normal thermal recovery of cold-work which occurred during the irradiation was virtually identical to that which occurred during an out-pile analysis of the post- irradiation annealing data for the 50 and 280 tained C irradiations revealed that in both cases the radiation damage anneals out in the range 250 to 400 tained C and is characterized by a single activation energy of approximately 2 ev throughout this range.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
