NON-DESTRUCTIVE TESTING OF LOW COBALT STAINLESS STEEL FUEL CLADDING FOR CORE 2, NS SAVANNAH

Specifications for the second core for the N.S. Savannah designated type 304 stainless steel with low Cobalt content for the fuel cladding and stated that tubing with any defects greater than 10% of the wall thickness in radial dimension could not be accepted. This report records the information obtained from evaluation of the non-destructive and destructive testing of low Cobalt stainless steel thin wall tubing. It is concluded that the standards and techniques currently employed for non-destructive testing of stainless steel tubing insure detection of defects in excess of 10% of the wall-thickness. The strength of the tubing is not appreciably reduced due to the presence of the small laminar inclusions or voids except under fatigue loading conditions which will not affect current reactor applications of the tubing.
