Achieving Indigenous Adoption and Sustainability

This study sought to develop a framework which would assist project implementers in their efforts to effectively indigenize technical and policy expertise in SNL's international partners. The initial assumption was that current and past projects undertaken by the Center for Global Security and Cooperation (CGSC) had produced many successful and effective tools and techniques to achieve indigenization and sustainability. As such, this study would be able leverage those tools and techniques to produce a common framework that would enhance SNL's ability to reproduce those past successes. Data was collected for this study by conducting a series of interviews and focus groups in order to elicit information about SNL's efforts and capabilities. The interviews focused on collecting data ranging from understanding definitions of sustainability and indigenization to financial considerations and various project management considerations. Initial findings showed that the problem statement originally formed in this study's hypothesis was missing elements of customer and in-country partner needs and goals which lead the interview team to adapt the original goal to determine what elements produced a success project rather than developing a framework. Overall the study found four main components that each successful project shared: the need to answer the right question, involve an institutional champion, the need to understand key stakeholders, and finally the need continually survey the project landscape.

Gas Migration Project: Risk Assessment Tool and Computational Analyses to Investigate Wellbore/Mine Interactions, Secretary's Potash Area, Southeastern New Mexico

The Bureau of Land Management (BLM), US Department of the Interior has asked Sandia National Laboratories (SNL) to perform scientific studies relevant to technical issues that arise in the development of co-located resources of potash and petroleum in southeastern New Mexico in the Secretary’s Potash Area. The BLM manages resource development, issues permits and interacts with the State of New Mexico in the process of developing regulations, in an environment where many issues are disputed by industry stakeholders. The present report is a deliverable of the study of the potential for gas migration from a wellbore to a mine opening in the event of wellbore leakage, a risk scenario about which there is disagreement among stakeholders and little previous site specific analysis. One goal of this study was to develop a framework that required collaboratively developed inputs and analytical approaches in order to encourage stakeholder participation and to employ ranges of data values and scenarios. SNL presents here a description of a basic risk assessment (RA) framework that will fulfill the initial steps of meeting that goal. SNL used the gas migration problem to set up example conceptual models, parameter sets and computer models and as a foundation for future development of RA to support BLM resource development.

Filtration testing for enhanced performance of Radionuclide Monitoring Stations for Nuclear Treaty Verification

A study of aerosol filtration was conducted to improve U.S. Radionuclide Monitoring Station (RMS) performance for Nuclear Treaty Verification. The primary objectives of this study were to improve system operability and maintainability, reduce power consumption and operational cost, and reduce baseline radionuclide sensitivity. To meet these goals, Sandia National Laboratories (SNL) studied the performance of alternate filter materials and aerosol collection technologies that could be engineered into U.S. Radionuclide Monitoring Stations. Laboratory-scale filtration experiments were conducted with Filter Material 1, FM1 (current filter), Filter Material 2, FM2, and Filter Material 3, FM3. All three materials employ electrostatically charged filter fibers to enhance nanoparticle collection. FM2 and FM3 both had higher air permeability with respect to FM1 which is advantageous for high volume collection and power savings. Particle pre-charging, a well-established industrial technique used in electrostatic precipitators, was tested to see if electrostatically charging particles prior to filtration could enhance filter performance. We found that particle-pre-charging did enhance aerosol collection efficiencies for materials which would not have otherwise satisfied RMS performance requirements. Laboratory-scale testing indicated it may be possible to reduce the baseline radionuclide sensitivity to approximately 60% of its current value by increasing the volume of air sampled in 24 hours to 2.5 times the current air volume. Improvements to geolocation may also be possible with shorter air samples (e.g., 12 hours). A new methodology was developed at SNL to assess filter performance using established RMS certification procedures. We coined these tests “mid-scale” since they bridged the gap between laboratory-scale and full-scale RMS testing. Four filter specimens were drawn from the exact same atmospheric aerosol. Gamma spectroscopy was used to assess radiological backgrounds due to radon progeny and other naturally occurring radionuclides. Direct comparisons between the four filters allowed SNL to quantify the relative change in baseline sensitivity by altering air flow rate, filter material, and particle-pre charging. Mid-scale results agreed with laboratory-scale results: alterations to RMS configuration (filter, flow, and particle charge) may result in baseline sensitivities approximately 55-60% of their current values. Finally, an assessment of scalability was performed to determine if technical approaches used in laboratory-scale and mid-scale testing could be engineered into full-scale Radionuclide Monitoring Stations. Results suggested that particle-pre-charging is a viable technical approach if reductions in baseline sensitivity or power consumption are desired.
