Environmental ISR (Quarterly Progress Report Q3 FY19 April-June 2019)

Progress have been good on both projects. On the subsurface radionuclide project, graduate student, Emily Tran, submitted our first joint manuscript resulting from this collaboration to Water Resources. The manuscript covers batch and flow through experiments using radionuclides with and without bentonite colloids through a naturally fractured chalk rock. Solutions used were collected from a field site in Israel with high ionic strength and filtered prior to using in the experiment. Results show that the bentonite colloids are unstable under these high ionic strengths in carbonate rock in Israel. The U is not significantly eluted with or without bentonite colloids and cerium precipitates as a mobile colloid in the absence of colloids.

Measurement of Fission Gas Release from Irradiated Fuel During Temperature Transients (Progress Report)

A device for real-time fuel heating observations and collection of fission gas release data is being developed to study nuclear fuel behavior during a temperature transient. The proposed system incorporates high heating and cooling rates, a digital violet laser microscope, mass spectrometry, and gamma ray spectrometry. By placing the system in a hot cell or in a hot cell–like enclosure, the capability could support study of a range of samples, including low and high burnup nuclear fuels. This report documents a conceptional design that incorporates a commercially available system that can be modified to achieve the desired specifications and proposed modifications. This report has been submitted in fulfillment of milestone M3FT-19OR020204082 titled, “Progress Report on Measurement of Fission Gas Release from Irradiated Fuel during Temperature Transient,” for the US Department of Energy Office of Nuclear Energy, Advanced Fuel Campaign of the Fuel Cycle R&D program.

Progress in Overcoming Materials Challenges with Supercritical CO 2 Recompression Closed Brayton Cycles

The supercritical carbon dioxide (S-CO2) Brayton Cycle has gained significant attention in the last decade as an advanced power cycle capable of achieving high efficiency power conversion. Sandia National Laboratories, with support from the U.S. Department of Energy Office of Nuclear Energy (US DOE-NE), has been conducting research and development in order to deliver a technology that is ready for commercialization. There are a wide range of materials related challenges that must be overcome for the success of this technology. At Sandia, recent work has focused on the following main areas: (1) Investigating the potential for system cost re duction through the introduction of low cost alloys in low temperature loop sections, (2) Identifying material options for 10MW RCBC systems, (3) Understanding and resolving turbine degradation, (4) Identifying gas foil bearing behavior in CO 2 , and (5) Identifying the influence of gas chemistry on alloy corrosion. Progress in each of these areas is provided in this report.

Strategic Petroleum Reserve Cemented Annulus Modeling and Testing; FY16 Progress

Sandia National Laboratories has begun developing modeling and analysis tools of flow through the cemented portion of a cemented annulus in a Strategic Petroleum Reserve (SPR) well since August of 2015. The goal of this work is to develop models and testing procedures to diagnose the health of cemented annuli at SPR sites. In Fiscal Year 2016 (FY16), we have developed several tests and associated models that we believe are sufficient for this purpose. This report outlines progress made in FY16 and future work.

Wood-to-Fuel for California's Transportation Sector using Autothermal Pyrolysis August 2019 (Progress Report for FRD-17-002)

What we planned to accomplish this period: In the month of August we planned to get any comments or edits on the Site License Agreement from SPI for review, make further progress on the market assessment for the Wood-to-Bio-oil Market Report, and continue moving towards getting the subcontracts in place with Iowa State University and Frontline BioEnergy, LLC. What we actually accomplished this period: We finally received the updated Site License Agreement from SPI on August 21st. The only comments and edits on it are minor and should not take more than a couple of weeks of review internally (the only reason this is weeks instead of days is due to the Laboratory’s fiscal year end approaching on September 30, making for heavily increased workloads on our folks that review these documents, and making a few weeks, instead of days, more realistic) before we can pass it along to Iowa State University and Frontline BioEnergy, LLC.

Progress Towards A New CTH Code Verification & Validation Test Suite

The CTH multiphysics hydrocode is used in a wide variety of important calculations. An essential part of ensuring hydrocode accuracy and credibility is thorough code verification and validation (V&V). In the past, CTH V&V work (particularly verification) has not been consistently well documented. In FY19, we have made substantial progress towards addressing this need. In this report, we present a new CTH V&V test suite composed of traditional hydrocode verification problems used by similar ASC codes as well as validation problems for some of the most frequently used materials models and capabilities in CTH. For the verification problems, we present not only results and computed errors, but also convergence rates. Validation problems include mesh refinement studies, providing evidence that results are converging.

Progress on a High Sensitivity, High Purity, One-Electron-One-Proton Search for the MiniBooNE Low Energy Excess in the MicroBooNE Detector

MicroBooNE is a large liquid argon time projection chamber (LArTPC) located at Fermilab. One of the experiments primary aims is to investigate the CCQE-like excess of ν ϵ events observed by MiniBooNE at low energy. A novel approach to analyzing LArTPC data using an amalgam of Deep Learning and traditional algorithms has been developed and is capable of end to end reconstruction and selection. We report here an overview and progress to event selection which yields greater than 99.999% rejection of backgrounds. Statistical, flux, and some cross section systematics have also been evaluated. Detector systematics and additional cross section systematics are still under study.

Sodium Fire Collaborative Study Progress (CNWG FY 2019)

This report discusses the progress on the collaboration between Sandia National Laboratories (Sandia) and Japan Atomic Energy Agency (JAEA) on the sodium fire research in fiscal year 2019. First, the current sodium pool fire model in MELCOR, which is adapted from CONTAIN-LMR code, is discussed. The associated sodium fire input requirements are also presented. A proposed model improvement developed at Sandia is discussed. Finally, the validation study of the sodium pool fire model in MELCOR carried out by a JAEA's staff is described. To validate this model, a JAEA sodium pool fire experiment (F7-1 test) is used. A preliminary calculation is performed using a modified MELCOR model from a previous experiment simulation. The results of the calculation are discussed as well as suggestions for improvement. Finally, recommendations are made for new MELCOR simulations for next fiscal year, 2020.

Nb 3 Sn Superconducting RF Cavities: R&D Progress at Fermilab and Opportunities

Nb 3 Sn becomes superconducting at twice as high temperature as our standard SRF material niobium. This allows us to efficiently operate Nb 3 Sn cavities at 4.4 K instead of the usual 2 K. This reduces cryogenic costs and even makes it possible to use a cryocooler instead of a large, complex cryogenic plant. The superheating field H sh of Nb 3 Sn is twice that of niobium. H sh is thought to be the ultimate limit for a defect-free superconductor. Nb 3 Sn cavities being made today are still about a factor of 4 away from this ultimate limit, but R&D has been leading to substantial progress towards this goal.

Wood-to-Fuel for California's Transportation Sector using Autothermal Pyrolysis (FRD-17-002 Progress Report)

In the month of December, we planned to have the Site License Agreement with SPI from them for final signatures, make further progress on the market assessment for the Wood-to-Bio-oil Market Report, and continue moving towards getting the subcontracts in place with Iowa State University and Frontline BioEnergy, LLC. The hope was to be able to get the finalized Site License Agreement back from SPI/Gary Blanc this month. Unfortunately, since we were in the immediate aftermath of fire season in California, and Gary was still unavailable as a result, we did not. Thankfully, it does not appear that there will be any major difficulties with getting the agreement finalized and signed, once Gary is available again, as SPI is constant in their support and eagerness for this effort to go forward, so we are not concerned that this is a risk to the project at this time. During the month of December, further research was completed on understand and evaluating the availability and potential availability of fire clearing, and other, forestry residue in California. Further investigations into the negative emissions of biomass pyrolysis products and their upgrading for use in other products (such as fuels) by incorporating carbon capture, drying and compression, and sequestration systems were conducted. The cost to achieve the maximum amount of negative emissions from these biomass-pyrolysis products with carbon capture and sequestration techniques was calculated. Sensitivity analysis was employed to understand how feedstock collection cost and product selling price affects this cost. We continued with the process towards subcontracting with Iowa State University and Frontline BioEnergy. Increased emphasis was placed on getting an updated budget from Frontline BioEnergy, LLC., so it can be submitted for approval of replacing a subcontractor, as we understand this is of utmost importance to the CAM. Frontline reported being very close to an updated budget, waiting on contracted labor costs remaining.

Progress on Synthesis of Low Content Inert Matrix Fuel Pellets

Progress was made on optimizing hot-press parameters for preparing fuel for two different coating methods: chemical vapor deposition (CVD) and chemical vapor infiltration (CVI). Surrogate materials, CeO 2 and ZrO 2 , were used in place of UO 2 and PuO 2 for fuel development. Although the more porous CeO 2 pellets were not successfully made to the extent that CVI would work with them as intended, hot-press parameters were optimized such that the pellets could be coated using CVD. The ZrO 2 was denser and therefore could more successfully be pressed to CVI standards; however, further improvement is needed before the process is implemented. Future work will continue to explore the optimization of a porous structure for CVI.
