2018 | ANNUAL REPORT 47 CINR - Joint R&D with NSUF Organization Title Project Description Aeroprobe 18-14788: IrradiationTesting of Mate- rials Produced by Additive Friction Stir Manufacturing Researchers will perform irradiation and post- irradiation examination of materials produced by the MELD manufacturing process (FKA additive friction stir (AFS)) and analogous advanced manufacturing tech- nologies. Compared with other additive manufacturing technique, MELD is much faster, generates a refined equiaxed structure, and does not require the post- manufacturing treatments needed for processes based on melting and solidification. Idaho National Laboratory 18-14772: Understanding Swelling- Related Embrittlement of AISI316 Stainless Steel Irradiated in EBR-II Researchers will investigate the swelling-related embrit- tlement behavior of AISI 316 stainless steels irradiated in fast reactor EBR-II at high neutron fluences. Massachusetts Institute of Technology 18-14783: Nanodispersion Strengthened Metallic Composites with Enhanced Neutron IrradiationTolerance Researchers will study the neutron irradiation tolerance of nanodispersion strengthened composites produced by an innovative manufacturing method at low cost. The prolific internal interfaces between 1D/2D nano- dispersions and the metal matrix provide radiation defect recombination venues to heal radiation damage. The success of this work will provide the novel concept of developing an innovative manufacturing method for advanced nuclear fuels and materials at low cost for long-term operation. Ohio State University 18-14749: Irradiation Behavior of Piezoelectric Materials for Nuclear Reactor Sensors The objective of this project is to perform a focused investigation of the irradiation behavior of piezoelectric aluminum nitride, a material considered as a highly attractive candidate for ultrasonic sensors in nuclear applications. In previous irradiation tests it has been identified as highly irradiation tolerant.The experiment will be designed to allow measurement of irradiation effects while isolating effects caused by transducer design. University of Notre Dame 18-14730: High-performance nano- structured thermoelectric materials and generators for in-pile power harvesting This project aims to develop radiation-resistant nano- structured bulk thermoelectric materials and devices for in-pile power harvesting and sensing.The thermo- electric power harvesting technology has crosscutting significance to expand nuclear reactor sensing, instru- mentation and offer major cost savings and enhanced safety for all reactor designs & fuel cycle concepts.
