Description

In order to assess the susceptibility of CANDU fuel bundles endplate resistance welds to Delayed Hydride Cracking (DHC) during long term dry storage, the threshold stress intensity factor (KIH) and crack velocity of DHC in endplate welds of three unirradiated fuel bundles were determined. The three bundles tested covered the 28-element and 37-element designs and two Canadian manufacturers. The range of KIH values and DHC velocities obtained from the endplate welds of the three bundles are consistent with previous results obtained from a 37-element bundle produced by one of the manufacturers.
