This tool provides high-level analysis on the incremental costs for retrofitting point sources with carbon dioxide (CO 2 ) capture and/or compression systems. Options are available to include costs of other technological improvements that would be required to comply with various regulations and New Source Performance Standards when installing CO 2 scrubbing technology.

Several analyses that will be completed as part of the Hanford Composite Analysis (CA) and Cumulative Impact Evaluation (CIE) require the extents of facilities, waste sites, and other locations on the Hanford Site. The purpose of this calculation is to provide spatial extents and consistent naming convention for those locations used as part of the analyses in a single dataset. This calculation documents the process used to develop the dataset.
The Nuclear Energy Agency (NEA) Ancillary data volume comprises thermodynamic data of mineral and aqueous species that, in addition to Auxiliary Data (as referred to in previous NEA thermodynamic data volumes), is necessary to calculations of chemical interactions relevant to radioactive waste management and nuclear energy. This SAND report is a review of the NEA Ancillary data critical reviews volume of thermodynamic data parameters. The review given in this report mainly involves data comparison with other thermodynamic data assessments, analysis of thermodynamic parameters, and examination of data sources. Only new and updated data parameters were considered in this review. Overall, no major inconsistencies or errors were found as allowed by the comparisons conducted in this review. Some remarks were noted, for example, on the consideration of relevant studies and/or comparisons on the analysis and retrieval of thermodynamic data parameters not cited in the respective sections.

This report provides a list of previous research supporting microreactor designs. For the purposes of this report, a “microreactor” will be defined as a reactor designed to produce less than 20 MW thermal while ensuring that the system is factory manufacturable, transportable (via truck, rail, or aircraft), and maintains neutronic simplicity (e.g., external controls) that can enable safe operation under semiautonomous or autonomous operation. The 20 MW thermal limit is based on the U.S. Department of Energy limit for a Hazard Category 2 (per 10 CFR 830 and DOE-STD-1027). Above the Hazard Category 2 limit, licensing activities would be required to be more detailed and robust. This does not eliminate higher-than-Hazard Category 2 reactors from consideration, but an increase in requirements typically means increased cost and time for development. Similarly, neutron simplicity is vital for minimizing the number of on-site operators; in turn, this enhances cost-competetiveness. Complicated designs do not eliminate reactors from inclusion in this report.

Naturalistic Driving Studies (NDS) collect and utilize data on drivers in real-world environments in instrumented vehicles. A common problem with such studies is driver privacy. In this work we collected a dataset of 77 human subjects performing scripted driving-related activities. We used three camera systems for the collection, including two high-resolution webcam devices as well as a third system from an actual NDS (the Second Strategic Highway Research Project, or SHRP2). This report covers the data collection process and summarizes the dataset, which will be made publicly available to researchers under a data usage license.
This tool provides high-level analysis on the incremental costs for retrofitting natural gas combined cycle plants with carbon dioxide capture and/or compression systems. Options are available to include costs of other technological improvements that would be required to comply with various environmental regulations when installing carbon capture technology. This model is based on the NETL report "Cost and Performance of Retrofitting NGCC Units for Carbon Capture" (2023).
This tool provides high-level analysis on the incremental costs for retrofitting pulverized coal plants with carbon dioxide capture and/or compression systems. Options are available to include costs of other technological improvements that would be required to comply with various environmental regulations when installing carbon capture technology. This model is based on the NETL report "Eliminating the Derate of Carbon Capture Retrofits." (2023).
