Abstract

AlBeMet 162 (Materion Co., formerly Brush Wellman) has been irradiated with 145 MeV protons up to 1.2x10²⁰ cm^-2 fluence, with irradiation temperatures in the range of 100-220oC. Macroscopic postirradiation evaluation on the evolution of mechanical and thermal properties was integrated with a comprehensive X-ray- diffraction study using high-energy monochromatic and polychromatic X-ray beams, which offered a microscopic view of the irradiation damage effects on AlBeMet. The study confirmed the stability of the metal-matrix composite, its resistance to proton damage, and the continuing separation of the two distinct phases, fcc aluminum and hcp beryllium, following irradiation. Furthermore, based on the absence of inter-planar distance change during proton irradiation, it was confirmed that the stacking faults and clusters on the Al (111) planes are stable, and thus can migrate from the cascade region and be absorbed at various sinks. XRD analysis of the unirradiated AlBeMet 162 showed clear change in the texture of the fcc phase with orientation especially in the Al (111) reflection which exhibits a “non-perfect” six-fold symmetry, implying lack of isotropy in the composite.

Engineered Zircaloy Cladding Modifications for Improved Accident Tolerance of LWR Nuclear Fuel

Technical Report Heuser, Brent ; Stubbins, James ; Kozlowski, Tomasz ; ...

The DOE NEUP sponsored IRP on accident tolerant fuel (ATF) entitled Engineered Zircaloy Cladding Modifications for Improved Accident Tolerance of LWR Nuclear Fuel involved three academic institutions, Idaho National Laboratory (INL), and ATI Materials (ATI). Detailed descriptions of the work at the University of Illinois (UIUC, prime), the University of Florida (UF), the University of Michigan (UMich), and INL are included in this document as separate sections. This summary provides a synopsis of the work performed across the IRP team. Two ATF solution pathways were initially proposed, coatings on monolithic Zr-based LWR cladding material and selfhealing modifications of Zr-based alloys.more »« less

Spall and damage behavior of S200F beryllium

Journal Article Adams, Chris D ; Anderson, William W ; Gray, George T ; ...

We have performed a series of plate impact experiments to study the strength and spall damage behavior of S200F Be. Peak stresses achieved were in the range from 5.6-19.2 GPa. VISAR data show long rise times in the approach to the shocked state believed to be the result of twinning occurring alongside, or in defference to slip, in this hcp material, with its free surface never achieving a steady velocity. This data indicate brittle spall behavior with spall strengths in the range of 0.8-0.9 GPa. In experiments where target thickness is varied, we see evidence of precursor decay and presentmore »« less

Radiation damage and thermal shock response of carbon-fiber-reinforced materials to intense high-energy proton beams

Journal Article Simos, N. ; Zhong, Z. ; Ghose, S. ; ... - Physical Review Accelerators and Beams

A comprehensive study on the effects of energetic protons on carbon-fiber composites and compounds under consideration for use as low-Z pion production targets in future high-power accelerators and low-impedance collimating elements for intercepting TeV-level protons at the Large Hadron Collider has been undertaken addressing two key areas, namely, thermal shock absorption and resistance to irradiation damage. Carbon-fiber composites of various fiber weaves have been widely used in aerospace industries due to their unique combination of high temperature stability, low density, and high strength. The performance of carbon-carbon composites and compounds under intense proton beams and long-term irradiation have been studied in a series of experiments and compared with the performance of graphite. The 24-GeV proton beam experiments confirmed the inherent ability of a 3D C/C fiber composite to withstand a thermal shock. A series of irradiation damage campaigns explored the response of different C/C structures as a function of the proton fluence and irradiating environment. Radiolytic oxidation resulting from the interaction of oxygen molecules, the result of beam-induced radiolysis encountered during some of the irradiation campaigns, with carbon atoms during irradiation with the presence of a water coolant emerged as a dominant contributor to the observed structural integrity loss at proton fluences ≥ 5 × 10²⁰ p/cm². The carbon-fiber composites were shown to exhibit significant anisotropy in their dimensional stability driven by the fiber weave and the microstructural behavior of the fiber and carbon matrix accompanied by the presence of manufacturing porosity and defects. Carbon-fiber-reinforced molybdenum-graphite compounds (MoGRCF) selected for their impedance properties in the Large Hadron Collider beam collimation exhibited significant decrease in postirradiation load-displacement behavior even after low dose levels ( ~ 5 × 10¹⁸ p cm^{more » $$-$$2} ). In addition, the studied MoGRCF compound grade suffered a high degree of structural degradation while being irradiated in a vacuum after a fluence ~ 5 × 10²⁰ p cm^{$$-$$ 2}. In conclusion, x-ray diffraction studies on irradiated C/C composites and a carbon-fiber-reinforced Mo-graphite compound revealed (a) low graphitization in the “as-received” 3D C/C and high graphitization in the MoGRCF compound, (b) irradiation-induced graphitization of the least crystallized phases in the carbon fibers of the 2D and 3D C/C composites, (c) increased interplanar distances along the c axis of the graphite crystal with increasing fluence, and (d) coalescence of interstitial clusters after irradiation forming new crystalline planes between basal planes and excellent agreement with fast neutron irradiation effects.« less

High-spin states in {sup 162}Ho have been populated in the reaction {sup 160}Gd({sup 7}Li, 5n) at a beam energy of 49 MeV. The K {sup {pi}}=1{sup -} band, the low-K Gallagher-Moszkowski (GM) partner band of known high-K(K {sup {pi}}=6{sup -}) band, based on the configuration {pi}7/2{sup -}[523]{center_dot}{nu}5/2{sup +}[642], and the K {sup {pi}}=6{sup +} band, the high-K GM partner band of known low-K(K{sup {pi}}=1{sup +}) band, based on the configuration {pi}7/2{sup -}[523]{center_dot}{nu}5/2{sup -}[523], have been identified. GM splitting energies, defined as {delta}E{sub GM}=E{sub int}{sup K-}E{sub int}{sup K,} 80 keV and -135 keV were extracted from these two sets of GMmore »« less

Proton irradiated graphite grades for a long baseline neutrino facility experiment

Journal Article Simos, N. ; Nocera, P. ; Zhong, Z. ; ... - Physical Review Accelerators and Beams

In search of a low-Z pion production target for the Long Baseline Neutrino Facility (LBNF) of the Deep Underground Neutrino Experiment (DUNE) four graphite grades were irradiated with protons in the energy range of 140–180 MeV, to peak fluence of ~6.1×10²⁰ p/cm² and irradiation temperatures between 120–200 °C. The test array included POCO ZXF-5Q, Toyo-Tanso IG 430, Carbone-Lorraine 2020 and SGL R7650 grades of graphite. Irradiation was performed at the Brookhaven Linear Isotope Producer. Postirradiation analyses were performed with the objective of (a) comparing their response under the postulated irradiation conditions to guide a graphite grade selection for use as a pionmore »« less
