Title: Internal strain measurement using pulsed neutron diffraction at LANSCE

Abstract

The presence of residual stress in engineering components can effect their mechanical properties and structural integrity. Neutron diffraction in the only technique that can make nondestructive measurements in the interior of components. By recording the change in crystalline lattice spacings, elastic strains can be measured for individual lattice reflections. Using a pulsed neutron source, all lattice reflections are recorded in each measurement, which allows for easy examination of heterogeneous materials such as metal matrix composites. Measurements made at the Manuel Lujan Jr. Neutron Scattering Center (LANSCE) demonstrate the potential at pulsed sources for in-situ stress measurements at ambient and elevated temperatures.

  • A variety of opportunities for characterization of fresh nuclear fuels using thermal (~25meV) and epithermal (~10eV) neutrons have been documented at Los Alamos National Laboratory. They include spatially resolved non-destructive characterization of features, isotopic enrichment, chemical heterogeneity and stoichiometry. The LANSCE spallation neutron source is well suited in neutron fluence and temporal characteristics for studies of fuels. However, recent advances in high power short pulse lasers suggest that compact neutron sources might, over the next decade, become viable at a price point that would permit their consideration for poolside characterization on site at irradiation facilities. In a laser-driven neutron sourcemore » the laser is used to accelerate deuterium ions into a beryllium target where neutrons are produced. At this time, the technology is new and their total neutron production is approximately four orders of magnitude less than a facility like LANSCE. However, recent measurements on a sub-optimized system demonstrated >10 10 neutrons in sub-nanosecond pulses in predominantly forward direction. The compactness of the target system compared to a spallation target may allow exchanging the target during a measurement to e.g. characterize a highly radioactive sample with thermal, epithermal, and fast neutrons as well as hard X-rays, thus avoiding sample handling. At this time several groups are working on laser-driven neutron production and are advancing concepts for lasers, laser targets, and optimized neutron target/moderator systems. Advances in performance sufficient to enable poolside fuels characterization with LANSCE-like fluence on sample within a decade may be possible. This report describes the underlying physics and state-of-the-art of the laser-driven neutron production process from the perspective of the DOE/NE mission. It also discusses the development and understanding that will be necessary to provide customized capability for characterization of irradiated fuels. Potential operational advantages compared to a spallation neutron source include reduced shielding complexity, reduced energy requirements, and a production target free of fission products. Contributors to this report include experts in laser-driven neutron production (Roth, Fernandez), laser design (Haefner, Siders, Leemans), laser target design (Glenzer), spallation target/moderator design (Mocko), neutron instrumentation and characterization applications (Vogel, Bourke).« less
  • The anisotropic expansion and contraction of YBa{sub 2}Cu{sub 3}O{sub 7-x} (YBCO) grains during fabrication could lead to internal stresses that may be relieved by microcracking resulting in low critical currents. Neutron diffraction techniques have been used to examine the internal strain as a function of grain size in samples of YBCO. The full width at half maximum (FWHM) of the Gaussian shaped diffraction peaks are used for the strain analysis. The FWHM in the strain distribution for the coarse grain material is found to be about 0.05%. The strain variation for the fine grained material on the other hand ismore » significantly larger and is about 0.3%. Results of this study suggests the strains are relieved by microcracking in coarse grained YBCO.« less
  • A program of measurements of low energy neutron spectra in moderators and typical sections of reactor cores is being planned to begin at General Atomic during the summer of 1958. This work will use the new high current 30 Mev electron linear accelerator to produce a very intense pulsed neutron source. The initial measurements of spectra will be done on hydrogen moderated systems both poisoned and unpoisoned. The characteristics of the linear accelerator and supporting facilities are described. The general features of the experimentai program are discussed and the two experimental techniques to be used in performing the spectral measurementsmore » are outlined. (auth)« less
