QUALITY STANDARDS AND TESTS FOR SWAGED FUEL CLADDING

Technical Report ·
OSTI ID:4051507
Cracking of Zircaloy cladding by the cold work induced in swaging was investigated. Two feeding devices were constructed to control the rate of translation and rotation of the rod during awaging. The first several batches of rods swaged and tested by fluorescent penetration had reject rates from 50 to 75%. However further investigation showed that the cause of the problem was the incoming tubing and not the swaging process. More than 60% of the incoming tubing showed some indications of pits, cracks, galling, and other defects. It was found that the swaging did not propagate and in some cases lessened their severity by reducing their depth. Tubes with no cracks before swaging were found to be defect-free after swaging.
