ICONE23-1374 THERMAL-HYDRAULICS ANALYSIS OF A RE-ENTRANT FUEL CHANNEL WITH UN FUEL FOR PRESSURE-CHANNEL SCWR
Bibliographic record
Abstract
This paper focuses on a generic Pressure-Channel (PCh) SuperCritical Water-cooled Reactor (SCWR) concept, which is one of the six Generation-IV nuclear technologies, featuring two-pass (re-entrant) counter-flow fuel-channel assembly. This generic PCh SCWR contains 336 vertical pressure channels (pressure tubes) and has a thermal power of 2540 MWth. Coolant is light water, and its temperature varies within the range of 350-625°C at a pressure of about 25 MPa. The objective of this paper is to perform a onedimensional steady-state thermal-hydraulic analysis of the reentrant-channel design with different types of fuels, namely UO_2 and UN. The thermal-hydraulics analysis was conducted while the 78-element fuel-bundle design was chosen as the reference fuel bundle.

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.
