Kinetics of fission-vaporized UO/sub 2/ fuel determined from sampled fuel debris. [LMFBR]

PDF Version Also Available for Download.

Description

Close-in time-resolved sampling of fuel aerosols, high speed photography, and photometric measurement of fuel temperatures were used to determine the thermal and kinetic characteristics of UO/sub 2/ fission heated to vaporization with a single 5 msec FWHM pulse of 2380 KJ/kg. From these data it was possible to obtain energy temperature relations and debris kinetics including particle size, velocity, density, momentum and pressure. These results demonstrate techniques for study of dynamic interactions involving liquid and vapor between fuel, cladding, coolant and structure and produce data important for determining initial HCDA aerosol formation.
