Abstract
An improved diaphragm design for use with a gasket in a pressure vessel manway opening to prevent leakage of a pressurized fluid was developed by B&W Canada. The design was developed for high pressure typical of conditions in the primary side of a PWR steam generators. The sealing is achieved by a spiral-wound graphite filled gasket which is confined in a separate diaphragm groove. The diaphragm has an internal radial groove which uses strong spring back and the pressure of the fluid to increase and maintain the gasket seating load. As a result, this design provides a self-energizing joint which can accommodate changes in gasket contact pressure due to cover rotation, stud elongation and change in fluid pressure and temperature. Finite Element (FE) Analysis indicates that a more uniform distribution of gasket contact pressure along the radial gasket width is obtained and thus the sealing performance of the gasket is improved.

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
