NON-DESTRUCTIVE ANALYSIS OF A PWR FUEL SEGMENT WITH A BURN-UP OF 50.4 GWD/THM – PART I: VISUAL EXAMINATION AND GAMMA-SCANNING

Abstract: 
Non-destructive analysis is an essential set of analyses for validation of the fuel rod safety and provides a valuable basis of information to plan and implement successful sampling. In a first step the pin was inspected visually for defects. These results were complemented by gamma-spectrometric measurements along the fuel pin. This provided first information about the actual pellet positions in the pin and the burn-up axial profile.
