SPATIAL AND BULK REACTIVITY SYSTEMS DESIGN AND OPTIMIZATION FOR THE CANADIAN SUPERCRITICAL WATER REACTOR
Bibliographic record
Abstract
A full-core reactor physics model of the Canadian SCWR concept was modeled, including proposed reactivity control devices. Fuel-integrated burnable absorbers and control blades, adjusted throughout the cycle, have been implemented in the fuel lattice cell to compensate for the excess reactivity. In addition to bulk reactivity control, the control blades provide radial flux shaping to minimize channel power fluctuations during the fuel cycle. As each channel has a static orifice at the inlet which imposes the coolant mass flow rate for a specific reference channel power, each channel power has to be maintained as close as possible to its designed power so that deviations from the target exit coolant temperature are minimized. The combination of burnable absorbers and variable insertion control rods ensures that the bulk and spatial reactivity is managed as well as maintaining channel powers as close to the reference as possible throughout the cycle. The analysis was performed by coupling the reactor core p...

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.
