Detection of protium, deuterium and tritium using ultrafast LIBS with rapid, standoff capability in addition to no sample preparation requirement which are crucial nuclear nonproliferation, safeguards, security
Designing a reliable target is already challenge for MW-class facilities today and has led several major accelerator to operate at lower than design power due concerns. With present plans increase beam next generation in the decade, timely R D support of robust high targets critical secure full physics benefits ambitious upgrades. A comprehensive program must be implemented address many complex challenges faced by multi MW intercepting devices. This roadmap envisioned helpful DOE-OHEP office...
With superior thermophysical and thermochemical properties, γ-LiAlO2 has high compatibility with other blanket materials is used in the form of an annular pellet tritium-producing burnable absorber rods (TPBARs) to produce tritium by thermal neutron irradiation 6Li. In radiation damaged γ-LiAlO2, different types vacancies, defects its constituent elements, trapping sites hinder diffusion process tritium. this study, first-principles density functional theory approach study mechanisms defect...
Abstract Molecular dynamics was employed to investigate the radiation damage due collision cascades in LiAlO 2 and LiAl 5 O 8 , latter being a secondary phase formed former during irradiation. Atomic displacement were simulated by initiating primary knock-on atoms (PKA) with energy values = 5, 10 15 keV quantified number of Frenkel pairs for each species: Li, Al O. The challenges modeling an ionic system without core–shell model oxygen addressed new findings on resistance these ceramics are...
A variety of SiC-Based composites and monolithic ceramics were characterized by measuring their thermal diffusivity in the unirradiated, annealed, irradiated conditions over temperature range 400 to 1000°C. The irradiation was conducted EBR-II doses 33 43 dpa-SiC (185 EFPD) at a nominal annealed specimens held 1010°C for 165 days approximately duplicate exposure specimens. Thermal measured using laser flash method, converted conductivity density data calculated specific heat values. Exposure...
Laser-induced breakdown spectroscopy is a promising method for rapidly measuring hydrogen and its isotopes, critical to wide range of disciplines (e.g. nuclear energy, storage). However, line broadening can hinder the ability detect finely spaced isotopic shifts. Here, effects varying plasma generation conditions (nanosecond versus femtosecond laser ablation) ambient environments (argon helium gas) on spectral features generated from Zircaloy-4 targets with compositions were studied....
Spatio-temporal mapping of species in a femtosecond laser induced Zircaloy-4 plasma identified conditions well-suited for the detection and analysis deuterium across wide range concentrations.
