DIMENSIONAL CHANGES RESULTING FROM ALPHA-BETA THERMAL CYCLING OF URANIUM AND URANIUM ALLOYS
Technical Report
·
OSTI ID:4332215
To obtain experimental data on the dimensional changes resulting from temperature excursions into the beta phase in uranium metal fuel slugs, specimens were thermal cycled above, below, and bracketing the alpha -- BETA phase transformation temperature. Results of variations in the rate of cycling with alpha-rolled, powder-compacted uranium and powder-compacted uranium alloys are described. Although the temperature gradients in these tests do not represent those to be encountered in reactor operation, the results indicate the relative stability of materials and the importance of further investigation of this problem.
