2014 ANNUAL REPORT 57 The facilities and capabilities available to me at CAES have been incredibly helpful in advancing my researchand I am looking forward to my future visits. Darin J.Tallman Ph.D.Candidate observed that in several instances the samples had either fused together or to the capsule making retrieval diffi- cult.The most troublesome capsules were the ones held at 1000C for the longest times.What is believed to have happened is that the materials swelled more than anticipated for the designed capsule volume.As many samples were recovered as possible and all samples have been separated and organized into storage vessels KGTs. Throughout FY 2014 DarinTallman scheduled several trips to INL for PIE characterization using equipment at CAES. Most capsules remain at HFEF where they are stored and await characterization. PIE characterization commenced in FY 2014 with capsules KGT1367 KGT1369 and KGT1371 corresponding to resistivity bars irradiated to 0.1 dpa at 100 500 and 1000C respectively.These were the most readily available capsules for decontamination and preparation as they had already been sent to EML for preliminary analysis. Samples were expertly cleaned and prepared by Karen Wright and Collin Knight at EML for shipment to CAES. Due to their high activity readings the resistivity bars were mounted in The carbides are exposed to a series of neutron fluence levels 0.1 1 and 9 dpa at moderate to high irradia- tion temperatures 100 500 and 1000C in the Advanced Test Reactor ATR at Idaho National Laboratory INL.The damage to the microstruc- tures and the effects of the radiation on the mechanical and electrical properties of the materials will be characterized during post-irradiation examinations.The results will provide an initial database that can be used to assess the microstructural responses and mechanical performances of these ternaries. Accomplishments This project is a collaborative effort between the INL Savannah River National Lab and Drexel University and was initiated in 2009.As noted above the team seeks to characterize the effect of neutron irradiation of select MAX phases for use in nuclear reactor applications. During the programs second year all irradiated samples were shipped to the PIE facility at INL. Unfortunately unavoid- able delays within INL throughout the FY 2013 continued to delay the project.The receipt cask unloading experiment disassembly and cata- loging of specimens have finally commenced led by Collin Knight. Upon opening the capsules it was
