ESTIMATES OF THE EFFECT OF BUBBLE SIZE ON FUEL ELEMENT SWELLING
Technical Report
·
OSTI ID:4188475
Fission gases are a source of swelling in irradiated fuel materials; in a mechanically strengthless material only surface tension limits the amount of swelling. In such materials, the ainount of swelling depends upon the operating temperature, fuel burnup, and the number of gas-filled bubbles per unit volume of material. Swelling is insensitive to the variety of sizes of the gas-filled bubbles, unless only a very smail proportion of the bubbles have an extremely large diameter. (auth)
