PERMISSIBLE UNSUPPORTED AREA OF PRTR MARK II FUEL ELEMENT CLADDING
Technical Report
·
OSTI ID:4304736
Void spaces between UO/sub 2/rings and cracks in the tubular fuel element caused by thermal expansion create minor areas of unsupported cladding. Testing of a metal slug and UO/sub 2/ fucl rings clad in 3.060 in. OD x 0.030 in. wall Zircaloy-2 tubing under pressures and temperatures equal to, or greater than, proposed PRTR conditions indicates that gaps equal to, or less than, 0.825 in. between sections of fuel may exist without cladding intrusion.
