2007:04 Link Between RI-ISI and Inspection Qualification: Relationship between Defect Detection Rate and Margin of Detection
Detection, POD) som en funktion av defektdjupet skulle vara idealt. Den vanligaste provningsmetoden i kärnkraftverk är ultraljud: Sannolikheten att finna en defekt beror på ett flertal olika parametrar ... såsom defektens djup, orientering, ytans jämnhet samt dess position och utformning, mm. Med detta i åtanke är det europeiska tillvägagångssättet för provningskvalificering vanligtvis baserat på en kombination...
