Post-irradiation examination completed during FY 2015 includes: (1) measure- ments of thermal conductivity using the laser flash method and specific heat using differential scanning calorimetry on nine specimens, (2) thermal expan- sion measurements on three specimens, (3) 3-D EBSD of one specimen, and (4) transmission electron microscope (TEM)/local electrode atom probe (LEAP) of one specimen. Future Activities Research yet to be completed on the irradiated material includes tensile and hardness tests on 12 specimens.This will be conducted at PNNL’s Material Science andTechnology Laboratory. Also to be completed are thermal diffusivity and differential scanning calorimetry measurements on the irradiated intermetallic material. Publications and Presentations* 1. Guillen, D. P., and H.
