The Evolution of Chemical Waste Treatment in the Nuclear Industry Simple Solutions for Complex Problems by Dr. Louis E. Centofanti

The Evolution of Chemical Waste Treatment in the Nuclear Industry Simple Solutions for Complex Problems by Dr. Louis E. Centofanti

March 31, 2017 | 1:30 pm  | EC Room 2300 Abstract A review of the nuclear waste treatment regulations indicates a lack of a rational environmental approach to deal with the problems of the nuclear industry’s waste. In fact, a few simple truths point out the depth of the problems at the federal level: No landfill standards, No treatment standards for radio isotopes of concern and rules that exist for high level waste…

Radiochemistry Center of Excellence: Expanding the Horizons of Nuclear Forensics Analysis

March 17, 2017 | 11:00 am  | AHC4 Room 302 Nuclear forensics analysis is a growing area of study that is defined as “The technical field of interpreting signatures and other clues in or about potential nuclear threats, such as nuclear materials that have slipped outside of regulatory control, nuclear devices that could produce nuclear yield, and other classes of radiological threats such as Radiological Dispersal Devices (RDD) and Radiological Exposure Devices (RED)”. Furthermore,…

“Soft X-ray Radiation Investigations of Materials Relevant to Actinide Science” by Dr. David K. Shuh

“Soft X-ray Radiation Investigations of Materials Relevant to Actinide Science” by Dr. David K. Shuh

September 3, 2017 | 3:00 pm  | MMC Campus | SIPA Room 220 Soft X-ray synchrotron radiation methodologies are being developed and employed at the Advanced Light Source (ALS) of Lawrence Berkeley National Laboratory to elucidate the electronic structure of actinide materials. Results from these investigations have begun to provide improved fundamental knowledge that can be used as a scientific basis for the enhanced design of special-purpose actinide materials and the overall understanding…

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…

Chemistry under Challenging Conditions by David T. Hobbs, Ph.D.

Chemistry under Challenging Conditions by David T. Hobbs, Ph.D.

“Chemistry under Challenging Conditions” November 14, 2016 | 11:00 AM | MMC Campus | CP Room 103 Managing the storage, retrieval, and disposition of legacy high-level nuclear waste and developing advanced nuclear fuel separation processes are challenging endeavors due to the complex chemical matrices and high radiation fields. At the Savannah River Site, the legacy waste from nuclear materials production are mixtures of precipitated metal hydroxides and hydrous metal oxides and highly…

“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…
