Long Baseline Neutrino Experiment (LBNE) Target Material Radiation Damage from Energetic Protons of the Brookhaven Linear Isotope Production (BLIP) Facility

In search of a low-Z pion production target for the Long Baseline Neutrino Facility (LBNF) of the Deep Underground Neutrino Experiment (DUNE) various grades of graphite were irradiated with 140-180 MeV protons to fluence up to ~6 10 20 cm -2 and irradiation temperatures in the range of 100-200oC. The objective of the irradiation experiment was to assess the radiation induced changes in the graphite onset by its interaction with energetic protons and deduce some measure of performance and survivability under the design conditions of LBNF. A multi-faceted post-irradiation evaluation was conducted to both qualify and quantify the induced material property changes. These studies included dimensional stability and thermal expansion, damage annealing via thermal cycling, high temperature post-irradiation annealing to mimic irradiation at elevated temperatures, stress-strain behavior, oxidation contribution to the postirradiation analysis, potential influence of the argon atmosphere under which irradiation took place, and lattice evolution. Dilatometry-based techniques were coupled with ultrasound-based annealing methodologies as well as DSC and TGA analyses. X-ray diffraction experiments assessed the lattice parameter changes and SEM analyses were used to study the different graphite grade structures. The multi-faceted post-irradiation evaluation, in conjunction with off-beam analyses, revealed some important facts regarding the choice of a graphite grade. Specifically, it was observed that the microstructure of a grade plays an important role in its dimensional stability. X-ray diffraction data indicated variability in basal plane spacing prior to irradiation with POCO d 002 =3.3833 Å, IG-430 d 002 =3.36814 Å and R7650 d 002 =3.37944 Å. Isotropic graphite grades such as POCO and IG-430 are confirmed to undergo microstructural shrinking under irradiation. All four irradiated graphite grades experience irradiation-induced creep leading to increased Young’s modulus with changes as high as 50% that varies with microstructure. X-ray diffraction on irradiated graphite confirmed previously made observations where under both energetic protons as well as fast neutrons of fluence > 5 10 20 cm -2 and at temperatures around 200°C acceleration of the effects on both the micro-and macrostructure is observed. Amongst the irradiated grades POCO graphite showed tendency to increase crystallinity order but also shows turbostratic state resulting from the interaction of its lattice with protons. This report presents and discusses the details of the irradiation experiment and the results of the postirradiation evaluation with main objective the assessment of the applicability and survivability of the selected four graphite grades as high-power accelerators pion production targets where the structural integrity, density reduction, dimensional and physical property stability are of paramount importance.

2018 Bryan Mound Baseline Casing Analysis

This report analyzes data from multi-arm caliper (MAC) surveys taken at the Bryan Mound Strategic Petroleum Reserve site to determine baseline statistics for the original innermost cemented casing or the subsequent installed liner. Along with analyzing the internal diameters from the MAC surveys, this analysis looks to approximate casing weight, an important metric for determining the strength of well sections. Casing weight is calculated for each section, survey, and well. Results from the analysis show most wells reflect the dimensions in the original as-built drawings. There are, however, a few exceptions. Some well sections have calculated wall thicknesses outside API tolerance. In addition, some well section depths differ from the as-built drawings. All results are discussed on a well-by-well basis. Where applicable, information from this report should be used to update as-built drawings and aid in creating more accurate well models for future studies.

Search For Short-Baseline Oscillations At The NOvA Near Detector

Anomalous results from past neutrino experiments have been interpreted as potential evidence for an additional sterile neutrino with a mass on order of 1 eV, but this evidence remains inconclusive. The NOvA Near Detector is a 293 ton almost fully-active fine-grained liquid scintillator detector, that was designed for electron-neutrino identification. The detector is placed along the Fermilab NuMI beam line 1 km from the target. At this off-axis angle, the detector is exposed to a narrow band beam peaked at 2 GeV. Therefore the NOvA Near Detector will see neutrinos with an L/E range that is sensitive to oscillations between active neutrinos and light sterile neutrinos. In this thesis, I discuss NOvA sensitivity from the joint electron-neutrino appearance and muon-neutrino disappearance analysis search for short-baseline sterile neutrino mixing.

Baseline Response of Silicon Strip Detectors and Comparison of Cost-Effective Amplifiers

Silicon strip detectors are a proven and more affordable technology. However, they are susceptible to high radiation damage. As part of the characterization of the effects of high radiation on silicon detectors, a baseline performance of these detectors under normal, low radiation conditions needs to be established. We did this by using an optimized setup and an infrared laser to simulate particle incidents. The detectors responded to applied bias voltage as expected. We then compared the performance of both economy amplifiers and an expensive amplifier as part of the optimized setup. For all intents and purposes, the economy amplifier worked just as well as the expensive amplifier.

Annual Energy Savings and Peak Power Reduction Simulated for CCHP Design and Baseline HP in Cold Climate Cities

This report assesses energy savings and peak power reduction of three heat pumps in multiple US cold climate cities and building types. The three heat pumps comprise a baseline heat pump and two high efficiency cold climate heat pumps (CCHP). The DOE/ORNL Heat Pump Design Model was used to simulate the heat pumps and generate performance curves for EnergyPlus building energy simulations. The annual energy simulations were performed over seven cold climates: 1) Minneapolis, MN; 2) Duluth, MN; 3) Fairbanks, AK; 4) Helena, MT; 5) Indianapolis, IN; 6) Peoria, IL and 7) Eagle County, CO. In order to assess impact of residential building types matching different energy codes, we simulated six single-family houses in Indianapolis, IN, including : 1) single-family house having a crawlspace; 2) having a slab foundation; 3) having a heated basement; 4) having an unheated basement; 5) one single-family house having a heated basement matching IECC code of 2009, 6) and one single-family house having a heated basement matching IECC code of 2012. The former 4 houses match the IECC 2006 code.

Baseline Postirradiation Examination of the FUTURIX-FTA Experiments

Postirradiation Examination (PIE) results from the baseline examination of the FUTURIX-FTA irradiation experiment are presented in this report. The FUTURIX-FTA irradiation was designed to study the fuel performance of candidate transmutation fuels. The FUTURIX-FTA experiment was conducted in the true fast neutron spectrum conditions of the Phénix sodium fast test reactor in France. FUTURIX-FTA contained several compositions that were also irradiated as part of the AFC-1 test in cadmium filtered positions in the Idaho National Laboratory (INL) Advanced Test Reactor (ATR) that approximate the neutron spectrum of a fast reactor. This experiment was a joint collaboration between the Department of Energy (DOE) in the U.S. and the Commissariat á l'Energie Atomique et aux Energies Alternatives (CEA) in France. A joint agreement between DOE and CEA was established in 2004 to conduct an irradiation experiment of metallic and nitride fuels in the Phénix reactor at CEA. Both the FUTURIX-FTA tests and the AFC-1 tests were conducted for the DOE Advanced Fuels Campaign (AFC) that is part of Fuel Cycle Research & Development (FCRD) program. These programs seek to develop and demonstrate the technologies needed to transmute long-lived transuranic actinide isotopes contained in spent nuclear fuel via fast reactor technology. The long term goal of this work is to reduce the radiotoxicity of future high level waste repositories. Post-irradiation examination of irradiated fuels experiments provides data related to in reactor fuel performance and input into future fuel design choices. The compositions of the FUTURIX-FTA pins were designed to test if minor actinides could be incorporated into the fuel of a fast reactor without significantly changing fuel performance observed for previously well studied fuels. The fuel performance of metallic fuel in fast reactors has been well documented. Likewise the irradiation performance of nitride fuels in fast reactors has also been documented. However the existing database for nitride fuels is much smaller than the database for metal fuels.
