LBNL-ESD researchers are currently supporting the Nuclear Regulatory Commission's need for further technical information about a set of related technical topics. The main objective of the project is to develop the technical basis for new NRC staff guidance to applicants and licensees on critical issues related to the seismic analysis and design of new nuclear power plants (NPPs), in the broad area of time-domain soil-structure-interaction (SSI) modeling.
High-Resolution Imaging of Geothermal Flow Paths Using a Cost-Effective Dense Seismic Network (CEC-EPIC)
Objective: Develop an advanced, low-cost, automated tomographic imaging system that uses micro-earthquakes and a dense network of portable, low-cost seismic sensors to form high spatial and temporal resolution images of subsurface fluid flow, including flow conduits, barriers and heterogeneity in producing geothermal fields...
The scientific mission of the HydroEcological Engineering Advanced Decision Support (HEADS) research group within the Earth Sciences Division at Berkeley National Laboratory is to develop techniques, technologies and computer-based decision support systems to enhance environmental monitoring, modeling and management.
EESA’s Genomes-to-Watershed and NGEE-Arctic projects seek to take advantage of new scientific software capabilities by incorporating a recently initiated DOE-Advanced Scientific Computing Research (ASCR)–BER-funded project, entitled Interoperable Design of Extreme-Scale Application Software (IDEAS). This project pursues the development and demonstration of new approaches for producing, using, and supporting scientific software. It will establish methodologies and tools that facilitate delivery of software as reusable, interoperable components.
This project seeks to explore the use of fiber optic sensing, particularly distributed acoustic sensing (DAS), to seismically characterize geothermal systems at the basin scale in California’s Imperial Valley.
We seek to understand geochemical processes using isotopic ratio and trace element concentration measurements. The research involves measurements of natural Earth systems and materials (rocks, soils, sediments, minerals, pore fluids, etc.) and products from laboratory experiments. The primary objectives are to (1) use isotopic effects to probe molecular- to micro-scale processes that control mineral precipitation…
Underground natural gas storage (UGS) in California serves winter heating and summer cooling demands, and there is no immediate alternative to meeting California’s demand for natural gas during peak periods in winter (e.g. CCST report, 2018). Therefore it is critically important to ensure the safety and integrity of UGS infrastructure, especially considering that many of…
Use of state-of-the-art lab facilities to develop the first integrated view of how soil physical, chemical and biological components interact from micron to meter scales to govern carbon and nitrogen biogeochemistry.
Since 2012, in an effort coordinated by Lawrence Berkeley National Laboratory, Spent Fuel and Waste Disposition (SFWD) Campaign has advanced active collaboration with several international geologic disposal programs in Europe and Asia. Such collaboration allows the SFWD Campaign to benefit from a deep knowledge base in regards to alternative repository environments developed over decades, and to utilize international investments in research facilities (such as underground research laboratory testing and modeling), saving millions of R&D dollars that have been and are being provided by other countries.
This project advances understanding and prediction of land-atmosphere interactions and greenhouse gas radiative forcing at Earth’s surface. We use observations to model the processes linking Earth's carbon, water, and energy cycles—from soil moisture and vegetation to clouds, radiation, and precipitation. We also observe the direct radiative effects of CO2 and CH4 on climate, using ARM spectroscopic measurements. Our research is yielding new insights into processes governing the water cycle over land, and is enabling rigorous testing of radiative transfer in climate models.
