Ultrasonic data will be taken in-situ. Subsequently, the sensors and couplant interfaces will be characterized using the LAMDA facility at ORNL. The results will be used to benefit a parallel EPRI project on online monitoring of cracks in LWR primary loop piping. | |

The focus will be on structural Compositionally Complex Alloys (four or more elements in a single-phase solid solution) relevant for high temperature nuclear applications. | |

This ability to point measure flux in ATR experiments in real time will substantially contribute to fulfillment of DOE-NE program objectives. | |

The PIE involves mechanical and microstrutural characterization using microhardness, tensile, electron backscatter diffraction, optical, tranmission electron microscopy and atom probe tomography techniques. | |

This information will be used to validate and/or improve the thermo-mechanical modeling of SiC/SiC tubes for accident tolerant LWR fuel applications. This experimental result will be compared with simulated lattice strains. | |

Researchers will use the Sandia Gamma Irradiation Facility (GIF) to expose nuclear cable insulation samples in sealed containers to a series of gamma doses at a series of dose rates. Oxygen concentration of the sealed containers and dielectric properties of the polymer samples will be measured pre- and post-irradiation. Lifetime curves of the insulation will be determined at more extreme accelerated conditions. | |
