IMPROVEMENT OF POINT LEPREAU GENERATING STATION ROP DETECTOR CHARACTERISTICS BY ADJUSTING GAINS IN COMPENSATION AMPLIFIERS
Bibliographic record
Abstract
Canadian Pressurized Heavy Water Reactors are protected against reactor overpower by 2 independent shutdown systems: Shut Down System 1 and 2. At Point Lepreau Generating Station, these shutdown systems can be actuated by signals from Platinum-clad Inconel In-Core Flux Detectors measuring the neutron flux. These detectors have a complex dynamic behaviour, characterized by “prompt” and “delayed” components with respect to immediate changes in the in-core neutron flux. In aging detectors, it was found that the prompt response decreases. A detector response that actuates the shutdown system effectively has to have a large prompt response and a small delayed response. These required responses may be obtained by adjusting the dynamic compensation amplifiers (compensator) settings. This paper presents the measured results of a compensation adjustment procedure for the in-core platinum-clad Inconel detectors. The compensation is computed from the detector parameters estimated by VS, a fully automated and qualified computer program that analyzes the response of the detectors.

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.
