Abstract
A shielded sample enclosure in the RMC SLOWPOKE-2 reactor is being investigated for future studies of irradiation effects on I&C cables. To inform the construction of the enclosure, half-power (10 kW) MCNP simulations were performed Compared to aluminum, zircaloy-4 and tungsten, lead was found to be most effective at selectively shielding gamma rays for various enclosure designs. The neutron flux and gamma dose rates calculated in the selected enclosure model with 1 cm of lead shielding were 1.81⋅10 10 n⋅cm -2 ⋅s -1 and 37.9 krad⋅hr -1 , respectively. The neutron flux and gamma dose rates were then measured in the constructed enclosure. The neutron flux ranged from 1.80⋅10 10 to 2.81⋅10 10 n⋅cm -2 ⋅s -1 , while the gamma dose rate ranged from 91.5 to 111 krad⋅hr -1 . Additional trials were performed using cadmium and boric acid shielding on the probe to protect against neutron interference on the gamma probe and rectify differences between the modeling and experimental results. Using cadmium, the gamma dose rate increased between 10 and 29%, and using boric acid, was decreased by 13%.

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 it
