Plutonium in the Environment: Can we Predict its Subsurface Behavior? by Dr. Annie B. Kersting

Plutonium in the Environment: Can we Predict its Subsurface Behavior? by Dr. Annie B. Kersting

“Plutonium in the Environment: Can we Predict its Subsurface Behavior?” December 15, 2016 | 2:0 PM | Applied Research Center | EC 2186 There is an acute need to expedite progress toward a permanent storage facility that can safely isolate long-lived actinides and fission products from the biosphere. Significant uncertainty remains on how to safely store long-lived radionuclides that will make up the majority of the dose after a few hundred years. Plutonium…

“Investigation of NH3(g) Treatment for the Immobilization of Uranium in the Presence of Pure Minerals” by Dr. Hilary P. Emerson, Post-Doctoral Fellow

“Investigation of NH3(g) Treatment for the Immobilization of Uranium in the Presence of Pure Minerals” by Dr. Hilary P. Emerson, Post-Doctoral Fellow

“Investigation of NH3(g) Treatment for the Immobilization of Uranium in the Presence of Pure Minerals” August 18, 2016 | 2:30 PM | FIU Engineering Campus | Room 2300 The injection of NH3(gas) is under consideration as a novel remediation technique for uranium at the DOE’s Hanford Reservation. The goal of NH3(gas) injection is to raise the pH to dissolve natural silicate and aluminosilicate from sediments. This should lead to co-precipitation…
