Abstract
ANALISIS KONSEP CANDU ADVANCED PASSIVE MODERATORPADA OPERASI NORMAL MENGGUNAKAN CATHENA. CANDU – advanced passive moderator (APM) mempunyai konsep, bahwa reaktivitas positif fraksi hampa dihilangkan dengan jalan mengurangi densitas moderator. Secara sederhana model CANDU APM terdiri dari kalandria, penukar kalor, pompa, dan tangki stabilizer, yang seluruhnya dihubungkan dengan sistem pemipaan. Kalandria dibagi atas 2 bagian, dimana bagian pertama mensimulasikan daerah air yang turun, sedangkan bagian yang lain mensimulasikan daerah air yang naik. Untuk mendemonstrasikan perlakuan termohidraulika konsep CANDU APM, digunakan perangkat lunak Canadian algorithm for thermalhydraulic network analysis (CATHENA). Telah dibuat simulasi dengan kondisi batas tekanan 300, 330, 360 kPa dan kondisi batas laju aliran air pendingin 2000 dan 3000 kg/s. Hasil awal memperlihatkan bahwa terjadi pendidihan dalam teras reaktor, sedangkan di penukar kalor terjadi kondensasi. Perlu dicatat bahwa hasil tidak mencapai keadaan tunak bila terjadi pendidihan.

How this classification was reachedexpand
Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
