Abstract
Abstract Pressure relief valves are installed on pressurized systems to mitigate consequences related to excessive pressure. Since relief valves come in discrete sizes, a relief system designer specifies a relief device with a rated capacity greater than the largest required relief rate. An oversized relief device is one in which a credible overpressure scenario exists; that is, the relief device capacity is more than a multiple (typically five times) the scenario's required relief rate. Most systems have more than one credible overpressure scenario (e.g., external fire or blocked outlet). In some other cases, installations in vapor service have been identified with an oversized relief device concern, without verification of whether or not these installations have a history of instability‐related damage (e.g., excessive relief device damage). Typically damage from oversized vapor relief devices is less severe than chatter which is caused by the coupling of the inlet line and the relief device, not the flow through the relief device. Some owners/operators have specified that oversized relief devices require mitigation. However, this paper shows why an oversized relief device in vapor service may not require mitigation.

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
