capability to fabricate functional materials and sensor devices for nuclear energy applications. The equipment will have crosscutting significance to advanced sensor and instrumentation research in multiple nuclear reactor designs and spent fuel cycles.
For Reactor Upgrades-
Idaho State University
Idaho State University will replace the BF3 detectors in the AGN-1 Reactor with modern B-10 lined detectors. The requested safety instrumentation upgrades will significantly modernize reactor operations, improve reliability, and allow students to train using current technology.
For Joint NEET/NEUP R&D with NSUF Access-
Boise State University
This project will investigate the microstructural and mechanical integrity of high irradiation fluence on laser weld repairs of previously-irradiated material. Studies will focus on neutron-irradiated AISI 304 stainless steel hex blocks, which contain high void number density and high helium concentration. These specimens will then be welded and subsequently ion irradiated to as high as 200 displacements per atom (dpa).
Idaho State University
Researchers will perform neutron irradiation and post-irradiation examination of bulk nanostructured austenitic and ferritic/martensitic (F/M) steels that are anticipated to have enhanced irradiation tolerance. Two innovative, low-cost manufacturing techniques will be used to manufacture the samples: equal-channel angular pressing (ECAP) and high-pressure torsion (HPT).
For Fuel Cycle Research and Development-
University of Idaho
The project aims to use a science-based approach to set guidelines of selecting dopants for developing fuel cladding chemical interaction (FCCI)-resistant metallic fuel systems for fast reactors. Lanthanide fission products migrate to the fuel-cladding gap leading to cladding breaches. The team will perform both theoretical modeling and experiments to arrive at the guidelines that are based on sound science. If successful, this can lead to breakthroughs in minimizing the FCCI effect. University of Idaho
Researchers will use unique capabilities to modulate the electrodeposition of actinides (depleted Uranium) and fission products (Ln) during nucleation and growth stages. The team aims to preclude formation of electrodeposits with dendritic morphology. Morphology of electrodeposits will be controlled by electrolyte composition.
