SUMMARY OF CREEP TESTS ON THE PIQUA OMR FLAT-PLATE FUEL ELEMENT

Technical Report ·
OSTI ID:4200448
The Piqua OMR design specifies a 750 deg F maximum surface temperature for the Al cladding on the fuel plates. The possibility existed that fuel element failure might occur as a result of creep of the cladding which could obstruct the flow channels. Test fuel elements were suspended in circulating coolant for periods up to 718 hrs at temperatures to 800 deg F. No evidence of creep was found. (W.D.M.)
