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.

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.
