UPDATING FISSION PRODUCT CHEMISTRY DATABASE BASED ON RECENT INVESTIGATION IN FUKUSHIMA-DAIICHI NUCLEAR POWER STATION (2) TEMPERATURE EFFECTS ON THE DEPOSITION BEHAVIOR OF CsOH AEROSOLS ON CONCRETE MAIN PHASE-CaCO<sub>3</sub>
Bibliographic record
Abstract
The trapping behavior of cesium (Cs) on concrete, such as pedestal and shield plugs, was assessed through multiple deposition tests of CsOH aerosols on concrete main phaseCaCO3 within a temperature range of 170oC to 570oC under humid conditions. The deposition rate of CsOH aerosols on CaCO3 as a function of temperature was examined. X-ray diffraction analysis revealed the presence of water-soluble Cs2CO3 on CaCO3 samples up to 420oC, but negligible detection above this temperature. This finding is supported by quantitative analyses of Cs weight gain and chemical analysis, demonstrating an increase in deposition rate up to 420oC, followed by a decline thereafter. The increased deposition rate is attributed to the chemical interaction between CsOH and CaCO3, while the diminished rate beyond 420oC may result from the decomposition of CaCO3 under steam, thereby reducing the available reactant for the chemical reaction with CsOH.

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.
