facilities are typically limited to iodine (NUREG-1320, NUREG-1140).

P ool F ires of 30% T B P-K erosin e

The ARFs for strontium from a large-scale 30% TBP-kerosine burn were reported by Sutter,

Mishima and Schwendiman (June 1974). One hundred and fifty liters (150 l) traced with

25 g of strontium nitrate were burned in ten 17-in. x 23-in. x 3-in. deep stainless steel pans

placed on concrete block above an 8-in. pool of water on the floor of a 12-ft x 12-ft cell of

insulating board held in a sheet steel silo. The combustible organic phase was not in contact

with an aqueous phase. Kerosine was floated on the surface of the water pool to aid in the

burning of the 30% TBP-kerosine PUREX-type solvent. The organic liquids were ignited

and the airborne materials carried to the exhaust gas treatment/sampling train apparatus

shown in Figure A.9 in Appendix A taken from the reference document (Figure 1 - Sutter,

Mishima and Schwendiman, June 1974). Two of the three burns generated usable data with

ARFs of 2.2E-3 and 1.9E-3. The values are generally consistent with those generated in the

small volume/surface area experiments in subsection 3.3.1.1.

Halverson, Ballinger, and Dennis (February 1987) reported measurements of airborne

uranium during the burning of combustible organic liquid over aqueous solutions. Small

volumes of liquid were placed in metal beakers (except in one case where a borosilicate glass

beaker was used to minimize the heat transfer through the beaker) on a load cell as shown in
