Abstract

fetched live from OpenAlex

The power conversion system will be an important part of the DEMO fusion power plants.One possible way to convert heat from a helium-cooled fusion reactor to electricity is by the Brayton cycle with supercritical carbon dioxide (sCO2) as a working fluid.This approach offers a smaller footprint and smaller initial cost of the system than the Rankine cycle does, mainly due to the small size of the turbomachinery and simplicity of the Brayton cycle.Heat exchangers (heaters, coolers, and recuperators) play a major role in the overall size and cost of the system.One of the most promising heat exchanger types for heaters and recuperators is printed circuit heat exchangers (PCHE).In this work, the size of PCHE between primary circuit and secondary circuit with sCO2 of the helium-cooled DEMO power plant is computed using Python script.Presented results show that overall volume of heaters for the DEMO strongly depends on channel geometry.

Full frame distilled prediction

Teacher imitation

Not 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.
