The determination covers the Department’s sales or transfers of no more than 2,705 metric tons (MTU) of natural uranium (NU) or NU equivalent in a calendar year. The proposed transfers include up to 650 MTU per year by the National Nuclear Security Administration in support of highly enriched uranium down blending activities, with the remainder of up to 2,705 MTU per year supporting accelerated cleanup activities by the Office of Environmental Management.
Energy Resources International (ERI), Inc conducted this independent market impact analysis on DOE planned uranium sales and transfers during the period 2014 to 2033, based on information concerning quantities and schedules provided to ERI by DOE.

This study provides a technical basis for informing policy decisions regarding strategies for the management and permanent disposal of spent nuclear fuel (SNF) and high-level radioactive waste (HLW) in the United States requiring geologic isolation.
The Nuclear Energy Advanced Modeling and Simulation (NEAMS) quarterly report includes updates, highlights, fuels and reactors product line accomplishments, integration accomplishments, recent and upcoming milestones.
This Test Plan for the High Burnup Dry Storage Research Project (HDRP) outlines the data to be collected, the high burnup fuel to be included, and the storage system design, procedures, and licensing necessary for implementation.
Clay and granitic units are potential host media for future repositories for used nuclear fuel. The report addresses the representation and characterization of flow in these two media within numerical process models. In low permeability crystalline rock, flow is primarily in relatively sparse networks of fractures.
The Nuclear Energy Advanced Modeling and Simulation (NEAMS) quarterly report includes highlights, fuel and reactor product line accomplishments, recent and upcoming milestones, BISON 1.0 release, MARMOT and SHARP news, fuel benchmarks, MeshKit 1.0 release, and information on neutronics and thermal hydraulics teams accomplishments.
The objective of this work is to develop a spatial database that integrates both geologic data for alternative host-rock formations and information that has been historically used for siting guidelines, both in the US and other countries. The Used Fuel Disposition Campaign (UFDC) is considering three alternative geologic host rocks for mined repositories (granitic / crystalline, salt, and clay / shale) and crystalline basement rock for deep borehole disposal. This report documents progress in populating a GIS Database with information concerning the distribution of alternative host rock
The newsletter features a recent meeting between Dr. Pete Lyons and current fellowship awardees, a highlight of Rita Patel, a FY 2012 fellowship recipient, and an update on a Fuel Cycle project studying high temperature sorption behaviors, led by Brian Powell at Clemson, along with other program updates.
International research collaborations on deep geological disposition of nuclear waste are a key aspect of the nation’s strategy to investigate disposal design concepts in geologic settings considered by other countries. This report centers on results obtained on THM simulations, reactive transport model development, and engineered barrier system (EBS) material characterization studies.
Active participation in international R&D is crucial for achieving the Used Nuclear Fuel Disposition long-term goals of conducting experiments to fill data needs and confirm advanced modeling approaches and of having a robust modeling and experimental basis for evaluation of multiple disposal system options.
This report documents the first phase of a multi-year project to understand the technical feasibility and logistical implications of direct disposal of spent nuclear fuel in existing dual-purpose canisters (DPCs) and other types of storage casks.
Contributions are described for the development of an enhanced generic disposal system modeling and analysis capability that takes advantage of high-performance computing (HPC) environments to simulate the important multi-physics phenomena and couplings associated with a geologic repository for UNF and HLW.
This Funding Opportunity Announcement (FOA) addresses the competitive portion of NE’s R&D portfolio as executed through the Nuclear Energy University Programs (NEUP) and Nuclear Energy Enabling Technologies Crosscutting Technology Development (NEET CTD). NEUP utilizes up to 20 percent of funds appropriated to NE’s R&D program for university-based infrastructure support and R&D in key NE program-related areas: Fuel Cycle Research and Development (FCR&D), Reactor Concepts Research, Development and Demonstration (RCRD&D), and Nuclear Energy Advanced Modeling and Simulation (NEAMS). NEET CTD supports national laboratory, university and industry led crosscutting research in the areas of reactor materials, advanced sensors and instrumentation, and advanced methods for manufacturing.
The Department of Energy’s (DOE) Office of Nuclear Energy (NE) conducts crosscutting nuclear energy research and development (R&D) and associated infrastructure support activities to develop innovative technologies that offer the promise of dramatically improved performance for advanced reactors and fuel cycle concepts while maximizing the impact of DOE resources.
The Nuclear Energy Advanced Modeling and Simulation (NEAMS) quarterly report includes highlights, fuel and reactor product line accomplishments, recent and upcoming milestones, news on BISON fuel benchmarks, the latest MeshKit release features, and information on numerical simulations of pebble-bed reactor cores performed by the thermal hydraulics team.
Enrico Fermi was the first scientist to achieve a nuclear fission chain reaction when he and a group of young scientists were experimenting at the University of Chicago on December 2, 1942. Using a “Jeopardy” format, this game features energy, electricity and nuclear science answers and questions.
