The report provides a technically based gas sampling frequency strategy for the High-Burnup (HBU) Confirmatory Data Project. The evaluation of 1) the types and magnitudes of gases that could be present in the project cask, and 2) the degradation mechanisms that could change gas composition culminates in an adaptive gas sampling frequency strategy. The adaptive strategy is compared against the sampling frequency that has been developed based on operational considerations. Comparison evaluation of the Technically based and Operationally based sampling frequency strategies indicates there
Nuclear energy represents the single largest carbon-free baseload source of energy in the United States, accounting for nearly 20 percent of the electricity generated and over 60 percent of our low-carbon production. Worldwide, nuclear power generates 14 percent of global electricity. Continually increasing demand for clean energy both domestically and across the globe, combined with research designed to make nuclear power ever-safer and more cost-effective, will keep nuclear in the energy mix for the foreseeable future.
This study has evaluated the technical feasibility of direct disposal in a geologic repository, of commercial spent nuclear fuel (SNF) in dual-purpose canisters (DPCs) of existing designs. The investigation considered waste isolation safety, engineering feasibility, thermal management, and postclosure criticality control. The 3-year study concludes that direct disposal is technically feasible for most DPCs, depending on the repository host geology. Thermal management and postclosure criticality control are two important aspects of disposability, and both of these could be relatively sim
On May 1, 2015, the Secretary of Energy determined that continued uranium transfers for cleanup services at the Portsmouth Gaseous Diffusion Plant and for down-blending of highly-enriched uranium to low-enriched uranium will not have an adverse material impact on the domestic uranium mining, conversion, or enrichment industry (“2015 Secretarial Determination”). This Determination covers continued transfers at the rates specified in the Determination.
The document summarizes how a new round of staged thermal field testing will help to augment the safety case for disposal of heat generating nuclear waste in salt. The objectives of the proposed test plan are to: (1) address features, events, and processes (FEPs), (2) build scientific and public confidence, (3) foster international collaboration, (4) evaluate disposal concepts, and (5) validate coupled process models. The test proposal is designed to address long term performance assessment (PA) and shorter term operational uncertainties.
To address the challenges associated with pursuing commercial nuclear power plant operations beyond 60 years, the U.S. Department of Energy’s (DOE) Office of Nuclear Energy (NE) and the Electric Power Research Institute (EPRI) have established separate but complementary research and development programs: DOE-NE’s Light Water Reactor Sustainability (LWRS) Program and EPRI’s Long-Term Operations (LTO) Program. INL/EXT-12-24562 Revision 4
The Light Water Reactor Sustainability (LWRS) Program is a research and development (R&D) program sponsored by the U. S. Department of Energy (DOE), performed in close collaboration and cooperation with related industry R&D programs. INL/EXT-11-23452 Revision 3
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.
The Department issued a Notice of Issues for Public Comment (NIPC) announcing the availability of the comments received in response to the Request for Information and market analyses prepared for the Department. The notice included a list of factors DOE had identified for analysis of the impacts of DOE transfers on the uranium mining, conversion, and enrichment industries, and a summary of information under consideration. The NIPC established a deadline of April 6, 2015, for the submission of written comments.
The Office of Nuclear Energy supports research and development for advanced reactor technologies. This report documents the results of the 2014 Technical Review Panel (TRP) review of seven advanced reactor concepts. The intent of the process was to identify R&D needs for advanced reactor concepts in order to inform Department of Energy (DOE) Office of Nuclear Energy R&D investment decisions.
On December 8, 2014, the Department issued a Request for Information on the effects of DOE transfers of excess uranium on domestic uranium mining, conversion, and enrichment industries. The Request for Information established a January 7, 2015, deadline for the submission of written comments. On December 24, 2014, the Department extended the comment period to January 22, 2015.
The Advanced Sensors and Instrumentation (ASI) newsletter will be released periodically to inform program stakeholders about new developments and achievements in the area of sensors, instrumentation and related technologies across the Office of Nuclear Energy (NE) R&D programs.
