Uranium Silicide/Nitride Pellet Fabrication Demonstration: Report on Powder Characteristics (Final CRADA Report)

This report details experimental procedures and results of work at the Idaho National Lab to fabricate U 3 Si 2 and UN ceramic powders from their basic elements. The reaction procedure centers on arc melting using a cold, copper hearth. The reacted "buttons" are then ground into powder, and the powder is characterized. The preliminary experiments utilized feeding pieces of metallic U and Si (in the proper ratio) into the arc-melting furnace for melting into "buttons." This melting was repeated several times with the intent of homogenizing the reaction to produce phase pure U 3 Si 2 powder. However, sintering of the pressed-powder at over 1400C showed partial melting and slumping of the pellets. Characterization of the powder using x-ray diffraction (XRD) indicated the crystalline portion of the powder was U 3 Si 2 . However, further investigations indicated a significant portion (12.4%) of the powder was amorphous Si that was transformed into crystalline Si after a period of annealing. Therefore, a greatly improved method of powder fabrication was developed using mixing fine powders of U and Si together, pressing into a pellet, followed by arc melting and grinding into U 3 Si 2 powder. This method was highly successful in producing high phase purity (>98.5% U 3 Si 2 ) powder. One feature of this method is that the fine U powder is made by a hydride/de-hydride cycle. The equipment available at INL only allows for fabrication of relatively small batches, and the method (using INL equipment) is somewhat labor intensive. The powder was used to successfully press and sinter U 3 Si 2 pellets ("Final Report on Pellet Fabrication," INL/LTD-13-29465). A limited attempt was made to fabricate high purity UN powder using the fine U powder made at INL (hydride/de-hydride method) and heating it under flowing nitrogen gas. X-ray diffraction was used to characterize the resulting powder, and a Rietveld refinement was performed on the data. The refinement showed a result of 70.0% UN and 30.0% U 2 N 3 . It is thought that the UN content can be easily increased

GeoVision Analysis: Reservoir Maintenance and Development Task Force Report (GeoVision Analysis Supporting Task Force Report : Reservoir Maintenance and Development)

This report documents the key findings from the Reservoir Maintenance and Development (RM&D) Task of the U.S. Department of Energy's (DOE), Geothermal Technologies Office (GTO) Geothermal Vision Study (GeoVision Study). The GeoVision Study had the objective of conduc ting analyses of future geothermal growth based on sets of current and future geothermal technology developments. The RM&D Task is one of seven tasks within the GeoVision Study with the others being, Exploration and Confirmation, Potential to Penetration, Institutional Market Barriers, Environmental and Social Impacts, Thermal Applications, and Hybrid Systems. The full set of findings and the details of the GeoVision Study can be found in the final GeoVision Study report on the DOE-GTO website. As applied here, RM&D refers to the activities associated with developing, exploiting, and maintaining a known geothermal resource. It assumes that the site has already been vetted and that the resource has been evaluated to be of sufficient quality to move towards full-scale development. It also assumes that the resource is to be developed for power generation, as opposed to low-temperature or direct use applications. This document presents the key factors influencing RM&D from both a technological and operational standpoint and provides a baseline of its current state. It also looks forward to describe areas of research and development that must be pursued if the development geothermal energy is to reach its full potential.

Reporting Verification of BOP Shear Ram Capability: Requirements and Good Practices on Reporting Blowout Preventer (BOP) Shear Ram Capability for Outer Continental Shelf (OCS) Oil and Gas Operations

The Bureau of Safety and Environmental Enforcement (BSEE) Well Control Rule (Subpart G)1 became effective on July 28, 2016. This rule is part of the BSEE regulations pertaining to well control equipment used for oil and gas operations on the U.S. Outer Continental Shelf (OCS). More recently BSEE issue a proposed rule to amend portions of the 2016 well control rule. This proposed rule (now implemented) appeared in the Federal Register on May 18, 2018. This report was prepared late in the public comment period for the current rule and intended is a sample of desirable documentation of blind shear ram shear testing and associated regulatory requirements either in place or anticipated at the time of preparation. In accordance with this original rule and the proposed revisions, BSEE requests specific information regarding the capabilities of blind shear rams (BSR) in the Blowout Preventer (BOP). This information is required prior to beginning any operation involving the use of any BOP. More specifically, Title 30 CFR 250.732(b) of these regulations requires documentation of shear testing demonstrating the shearing and sealing capabilities of the BOP BSR. Such documentation is consistent with and complementary to other documentation verifying the designs of individual well control components and the overall BOP system. Verification demonstrates performance and reliability of the equipment based on a testing process that is repeatable and reproducible.2 This document, an annotated outline of verification documentation, arises from the combination of regulations and good practices concerning how to report BOP shear ram tests and third-party verification of BSR capability to support BSEE’s regulatory role.

Report series: Evaluation, Finding of Effect, and Mitigation Documentation for the 1960s Dormitories and 1950s Quonset Hut Foundations, Mercury, Area 23, Nevada National Security Site, Nye County, Nevada [3 Reports Consolidated]

The U.S. Department of Energy, National Nuclear Security Administration Nevada Field Office (NNSA/NFO) plans to modernize the town of Mercury at the Nevada National Security Site (NNSS) in Nye County, Nevada, to meet current and future National Weapons Science, Global and Homeland Security Programs, and Environmental Management mission requirements. These plans—including anticipated demolitions, consolidations, and rebuilding at Mercury—are considered an undertaking subject to review under Title 54 U.S.C. § 306108, commonly known as Section 106 of the National Historic Preservation Act, Title 54 U.S.C. § 300101, et seq., and its implementing regulations, 36 C.F.R. Part 800. Desert Research Institute (DRI) completed an architectural survey of Mercury in 2017. This effort resulted in the identification, recording, and evaluation of the Mercury Historic District, as well as the identification of its contributing components. This district was recommended eligible to the National Register of Historic Places (NRHP or National Register) under Criteria A and C, but was unevaluated under Criteria B and D at that time. The Mercury Historic District contains 153 individual landscapes, buildings, and structures. Of these resources, DRI recommends all except one as contributing elements of the historic district during its period of significance corresponding to nuclear testing from 1951 through 1992. During most of the Cold War, the land now called the NNSS was referred to as the Nevada Test Site (NTS). This report evaluates resources dating to the 1950s and 1960s between Jangle and Knothole Streets and south of Ranger Avenue in Mercury prior to the proposed demolition of all resources in that area between Sandstone and Greenhouse Avenues as a phase of the larger modernization program mentioned above. Although the Mercury Historic District as a whole is eligible to the National Register, further evaluation of these properties, as detailed in this report, indicates that none are individually eligible under any of the Secretary of Interior’s Significance Criteria, either at the national or local level.

ULTIMATE FY22 Creep Test Facility Report (FY23 ARPA-E Milestone Report)

In the 18-month Phase 1 of this project, a facility was assembled for creep testing of refractory metals at 1300°C. This report focuses on the four creep frames that are operational and using an inert gas system (argon) to limit oxidation of the refractory metal specimens being tested. This report details the operations for the first period of operation including the results and lessons learned for Nb- and Mo-based alloy specimens tested by the ORNL team. For an alloy development program, a particularly unique feature of the ORNL facility is more than 40 years of experience conducting mechanical properties testing on sub-sized test specimens (25 mm long dogbones). Due to proprietary constraints, only one representative set of team data are provided. The primary concern for testing Nb-based alloys is oxygen ingress. Despite several strategies to reliably limit O ingress, including getters and Ar gas purity, the experimentally informed strategy currently being developed is a new load train design intended to better seal the system. Hardware for the new design is currently being fabricated.

Pioneer WEC concept design report

The "Pioneer WEC" project is targeted at developing a wave energy generator for the Coastal Surface Mooring (CSM) system within the Ocean Observatories Initiative (OOI) Pioneer Array. The CSM utilizes solar photovoltaic and wind generation systems, along with rechargeable batteries, to power multiple sensors on the buoy and along the mooring line. This approach provides continuous power for essential controller functions and a subset of instruments, and meets the full power demand roughly 70% of the time. Sandia has been tasked with designing a wave energy system to provide additional electrical power and bring the CSM up-time for satisfying the full-power demand to 100%. This project is a collaboration between Sandia and Woods Hole Oceanographic Institution (WHOI), along with Evergreen Innovations, Monterey Bay Aquarium Research Institute (MBARI), Eastern Carolina University (ECU), Johns Hopkins University (JHU), and the National Renewable Energy Laboratory (NREL). This report captures Phase I of an expected two phase project and presents project scoping and concept design results.

Advanced Algorithms for Scrutiny of Mandatory State Reports Declarations to the IAEA (Final Project Report)

In compliance with their Comprehensive Safeguards Agreements, based on INFCIRC/153 (corrected) (International Atomic Energy Agency, 1972), States Party to the Treaty on the NonProliferation of Nuclear Weapons (NPT) are obligated to declare to the International Atomic Energy Agency (IAEA) all changes in their nuclear material inventory as well as movement of the material across boundaries of IAEA recognized material balance areas (MBA), inventories and nuclear material balances. This project addresses capabilities to detect irregularities in State reports, thus ensuring their accuracy and completeness, and in the broader context, States’ compliance with safeguards obligations of the NPT. A recent study (Henzl et al., 2022) (lead by this project’s PI) demonstrated how analysis of dynamic correlations in nuclear material movement within the entire fuel cycle of a State (viewed as a single system) can reveal variances consistent with and indicative of “irregular” activities. Expanding on this concept, novel ways to analyze State declarations themselves—again, for the State as a whole entity—will help the IAEA draw accurate safeguards conclusions and trust the validity and authenticity of Stategenerated declaration reports. Introducing new declaration analyses capabilities explored in this project will help to provide credible assurance of both the non-diversion of nuclear material from declared activities and of the absence of undeclared nuclear material and activities in the State in general.
