RCT Module 2.15 Radiological Considerations for First Aid [Presentation]
Standard first aid is applied before contamination control whenever it is considered to have life-saving value or is important to the patient for the relief of pain or prevention of disability. It is the obligation of all who assist a patient to render such aid within the limits of their training and qualifications.
Assessing the Resource Adequacy and Community Impacts of an Evolving Grid: Considerations for State Regulators
As U.S. power systems continue to decarbonize, state regulators must be able to broadly assess the cost and reliability implications of proposed fossil retirements and the corresponding resources that are coming online to replace them. Specifically, regulators must evaluate whether proposed infrastructure investments are sufficient to ensure the long-term reliability of the system, while also protecting rate payers by ensuring that such investments are necessary and not excessive. Broadly speaking, this objective is typically framed in terms of maintaining long-term resource adequacy at the lowest cost, while also ensuring that other social and/or environmental objectives are satisfied. System planners currently have a host of sophisticated analytical tools at their disposal to evaluate the cost-benefit trade-offs of different approaches to ensuring resource adequacy. However, most of these tools and associated metrics were designed with traditional power systems in mind. Over the past decade, it has become increasingly clear that the metrics and models that have reliably assessed resource adequacy in systems dominated by large thermal and hydropower resources will be insufficient for systems with significant contributions from emerging technologies such as wind, solar and storage. Therefore, in recent years many new metrics and modeling approaches have been developed, and are increasingly being implemented, to meet the needs of the clean energy transition.
Corrosion Testing Needs and Considerations for Additively Manufactured Materials in Nuclear Reactors
The Advanced Materials and Manufacturing Technologies (AMMT) program within the Department of Energy, Office of Nuclear Energy (DOE-NE) has developed its current recommendation for its corrosion testing strategy to deploy additively manufactured (AM) materials in advanced nuclear reactors. Additive manufacturing technologies have developed rapidly in recent years, creating new opportunities and challenges for the nuclear industry. To adopt AM technologies, the corrosion performance of AM materials needs to be adequately evaluated.
Capacity Density Considerations for Offshore Wind Plants in the United States
The United States is a rapidly emerging market for offshore wind energy, with a project pipeline estimated at over 52 GW as of May 31, 2023 (Musial et al. 2023). The capacity density, measured in megawatts per square kilometer (MW/km 2 ), is a crucial parameter for estimating the magnitude of the development pipeline and the nameplate potential of existing lease areas. The offshore wind energy industry is comprised of diversity of participants, including developers, governmental bodies, investors, environmental advocacy groups, and researchers. These various stakeholders use capacity density in different ways as a key metric for evaluating the potential of individual offshore wind lease area or even a section of ocean space. This report presents our assessment of capacity density values in the current pipeline of emerging U.S. offshore wind farms and a detailed list of the main factors that influence capacity density. This understanding is critical for planning of future lease areas, for estimating the technical resource potential for offshore wind on the U.S. outer continental shelf (OCS), and for estimating ocean space requirements needed for meeting state and national goals for a carbon neutral energy transition.

Fuel Flow Modeling under Thermal Fluidics Considerations within Operational Domains of Molten Salt Reactors
Molten Salt Reactors (MSRs) offer significant versatility supported by their design flexibility and safety advantages due to high temperatures, design customization capabilities, strong negative reactivity feedback effects, and salt chemistry characteristics. Different control schedules and different mass flow rates in the MSR primary systems impact neutronics and thermal hydraulics coupling. The result is two-fold. First, it leads to adaptability in various applications when the customization of a MSR unit is desired. Second, it calls for the quantification of dynamics and safety characteristics to assess the operational domain and make sure reactor stability and inherent safety characteristics are maintained. This paper provides an in-depth transient analysis of the operational implications of MSRs having heat-generating fuel and heat-transporting salt mixed forming liquid fuel salts contained within primary systems. A coupling model was developed to simulate fuel flow in molten salt reactors. A zero-dimensional reactor kinetics model was used with a one-dimensional heat transfer model in the reactor core. The temperature reactivity feedbacks of the fuel salt resulting from the thermal-hydraulics model were used in the reactor kinetics model to complete the coupled code. The model was applied to simulate the Molten Salt Breeder Reactor (MSBR) response at steady state and transients. The developed model was shown to be a suitable tool for the dynamic analysis of molten salt reactors.
Considerations for Export Control of Accelerators and Accelerator Components
Although nuclear reactors have been the sole source for producing plutonium in all nuclear weapons states, accelerator-driven subcritical reactors are a tantalizing alternative. This report provides a review of accelerator driven technologies and components with a focus on export control.
Energy Justice Framework for Marine Energy: Considerations from PacWave
To accelerate the energy transition while addressing land use conflicts and community opposition, federal policies and incentives require that new energy infrastructure provide direct benefits to communities, and ensure that these benefits remain in the community. The objective of this study is to develop a framework for collecting demographic, socioeconomic, and environmental data and supporting communities in understanding how such data can support more just and equitable outcomes. Specifically, this study addresses two research questions: (1) How can energy justice be incorporated into ME project life cycle, and (2) what social and economic data are needed to assess how marine energy development supports energy justice? Based on our literature review and the data collection template, a case study of PacWave, a wave energy testing facility located on the central Oregon Coast, is employed to draw more specific implications for how energy justice can be integrated into marine energy. PacWave represents a flagship investment by Oregon State University, the State of Oregon, and the Department of Energy. The facility is situated in Lincoln County, which is home to the Confederated Tribes of Siletz Indians and family-scale fishing enterprises. PacWave has strong community support as a testing site and holds potential to provide valuable lessons for other communities.
