Abstract: Regardless of aqueous and non-aqueous techniques, conventional reprocessing is not accessible for many countries running nuclear power plants due to Pu diversion concerns. Considering that only some of the fission products present in used nuclear fuel dominate the environmental impact of a final waste repository, removing them selectively whilst retaining the actinides in solid …
Abstract: After a 35-year hiatus, Lawrence Livermore National Laboratory is executing a series of experiments looking at the thermostructural response of materials at the Annular Core Research Reactor (ACRR). The purpose of these experiments is to help validate a radiation transport code and a finite element structural code used at the laboratory. The radiation transport …
Abstract: The Versatile Test Reactor (VTR) program is aiming at designing and building an advanced test reactor in the U.S. within 10 years. This reactor will bridge the current capability gap in irradiation capabilities, effectively supporting development of all types of advanced reactors through enabling accelerated material and fuel testing. At this stage, the VTR …
Co-Hosted with NSSC Abstract: The Single Volume Scatter Camera (SVSC) Collaboration is multi-institution effort lead by Sandia National Laboratories to develop portable neutron imaging systems for a variety of applications in non-proliferation and arms control. Current state-of-the-art kinematic neutron imaging systems consist of distributed scintillator volumes in which the position, time, and energy of multiple …
Abstract: This colloquium will discuss why it is important to embrace quality assurance principles for research programs in order to create a competitive advantage, enhance the research reputation, and gain customer confidence: "delivering the goods". Bio: Mr. Daren Jensen is the owner of Optimum Performance Solutions consulting and has over thirty-three years of experience in …
Abstract: To design a fusion reactor with tritium self-sufficiency, and for safe operation of molten salt reactors, it is essential to understand tritium chemical and mass transport behavior in the coolant and the solid structural materials. In order to operate a fusion reactor continuously, tritium must be produced in the blanket of the fusion reactor, …
Abstract: China today, after three decades of forced development and deployments, is poised to become the world's leading nuclear power country during the first half of this century. If China succeeds, it will surpass all advanced nuclear power countries that failed so far to effect a transition from light-water reactors to fast reactors with a …
Abstract: Most nuclear waste repository options include an engineered barrier system surrounding waste containers in order to minimize the release of radioactive contaminants into the environment after waste package failure and waste form degradation. The proposed buffer material in these barrier systems is compacted bentonite, a natural, geologic material largely consisting of montmorillonite clay. Uranium …
Abstract: It’s not immediately intuitive to think of an explosion as a reducing environment. After all, a conventional explosion is an oxidative process. In the case of a nuclear explosion; however, it has been known since 1975 that large amounts of iron in the surrounding environment can be reduced to its ferrous form.1 An explanation …
Abstract: In many ways, nuclear power has never been more needed than right now, but the challenges that nuclear power is experiencing in many parts of the world are substantial and largely tied to economics. In the U.S., plants are shutting down before the end of their licensed lifetime. There are several factors at play, …
