Characterization Of Supernate Samples From High Level Waste Tanks 13H, 30H, 37H, 39H, 45F, 46F and 49H

Strontium and Actinide Sorption by MST and MMST Under Conditions Revelant to the Small Column Ion-Exchange Process

“…13H, 30H, 37H, 39H, 45F, 46F, and 49H). 6 Tank 39H had a measured soluble Pu content of 1.13 mg/L; however, the next highest measured Pu concentration was 0.0081 mg/L (Tank 37H). The U and Np concentrations of 10 and 0.5 mg/L, respectively, bound all 7 of the previously mentioned tanks.…”

“…7 After adding the sorbents, the bottles were placed in the waterbath shaker, maintained at an average temperature of 23.59 ± 0.67 °C, and were continually shaken. Samples were removed at times of 6,12,24,48, and 72 hours, and then weekly for a total of 6 weeks. At each sampling event, the bottle was removed from the waterbath and manually shaken for 30 seconds to ensure the solids were homogeneously suspended.…”

RADIUM AND THORIUM SORPTION BY MONOSODIUM TITANATE (MST) AND MODIFIED MST (mMST)

“…7 For this testing, we selected a target concentration of natural abundance thorium of 2.0 mg/L to ensure that the simulant was saturated with Th(IV).…”

Literature Review on Maximum Loading of Radionuclides on Crystalline Silicotitanate

“…For example, Tank 13H has a total Ba concentration of 4.84 µg/mL. 10 In other words, running 3,000 BV of a Cs-free feed solution containing Ba at 0.533 mg/L and other RCRA metals would most likely result in a higher Ba loading on CST than, say, 1,000 BV of a Cs-laden feed containing Ba at 4.84E µg/mL. This is because the sorbent has the greatest affinity for Cs.…”
