Sizing small defects in PWR vessel safety injection nozzle welds

  • 1. Vincotte, Brussels (Belgium)
  • 2. Kerncentrale Doel (Belgium)

Description

Details of a new method of inspection of PWR vessel safety injection nozzle welds by ultrasonics are given. Field application of the method in Doel-1 revealed many small defects in the region of both safety injection nozzles. In particular, the large indications revealed by a previous in-service inspection, appeared to be clusters of such small flaws, obviously integrated into single signals as a consequence of the sound beam dimensions
