Welds of 309SCb corrode at a rate much faster than that of the wrought metal in boiling HF--HNO/sub 3/ systems, although the weld and wrought metal corrode at about equal rates in HF alone. When a 309SCb dissolver is used for processing Detroit-Edison core elements, a satisfactory alternative to dissolving in HNO/sub 3/ containing a low concentration of HF is to remove the cladding of zirconium with dilute HF, and then to dissolve the core alloy (10% Mo --90% U) by addition of HNO/sub 3/ containing a small amount of Al(NO/sub 3/) to complex free fluoride. (For preceding period see DP-338.) (auth)
