Akers, D W; Johnson, D A

Cesium release, turbidity and airborne potential tests were conducted on 50 grams of TMI-2 core debris materials. The tests were performed on the debris in two stages: (1) undisturbed, without fracturing the debris particles; and (2) disturbed, after crushing the debris particles. Crushing the debris had minimal impact on turbidity. In general, the opacity of both solutions decreased at about the same rate (within a factor of 2). Crushing the debris increased the soluble /sup 137/Cs concentrations a factor of 4 to 5. Most of the airborne activity occurred near the end of the evaporation process, just prior to dryout. The increase in airborne concentration at this time is two to three orders of magnitude higher than at any other time.
