Breed-and-burn Molten Salt Reactors are an interesting option of reactor design that allow high fuel utilization while operating on open cycle. Such reactors usually require specialized codes in order to model its cycle and the flowing unmoderated core. In this work, we propose a perform preliminary analysis homogeneous chloride salt single-fluid design. The is analyzed using EQL0D tool start-u...
The Rayleigh-Taylor instability in its highly nonlinear, turbulent stage causes atomic-scale mixing of the shell material with the fuel in the compressed core of inertial-confinement fusion targets. The density of shell material mixed into the outer core of direct-drive plastic-shell spherical-target implosions on the 60-beam, OMEGA laser system is estimated to be 3.4(+/-1.2) g/cm(3) from time-...
A parametric systems model of the ATW [Accelerator Transmutation of (Nuclear) Waste] has been used to examine key system tradeoffs and design drivers on the basis of uni t cos ts . This model has been appl ied primarily to the aqueous-slurry blanket concept for an ATW that genera tes net -e lec t r ic power f rom the fissioning of spent reactor fuel. An important goal of this s tudy is the deve...
A controlled fire burner was constructed where various natural vegetation species could be used as fuel. The burner was equipped with thermocouples to measure fuel surface temperature and used as a cavity for microwaves with a laboratory quality 2-port vector network analyzer to determine electrical conductivity from S-parameters. Electrical conductivity for vegetation material flames is import...
In this paper, we applied landscape scale wildfire simulation modeling to explore the spatiotemporal patterns of wildfire likelihood and intensity in the island of Sardinia (Italy). We also performed wildfire exposure analysis for selected highly valued resources on the island to identify areas characterized by high risk. We observed substantial variation in burn probability, fire size, and fla...
This work deals with the representation of homogenized few-groups cross sections libraries by machine learning. A Reproducing Kernel Hilbert Space (RKHS) is used for different Pool Active Learning strategies to obtain an optimal support. Specifically a spline kernel and results are compared multi-linear interpolation as in industry, discussing reduction library size overall performance. standar...
The burn-up code MOTIVE is a 3D for fuel assembly inventory determination developed at GRS in recent years. It modularly couples an external Monte Carlo neutron transport to the in-house VENTINA. In present publication, we report on validation of with respect full-assembly decay heat measurements light water reactor fuel. For this purpose, pressurized and boiling assemblies from different facil...
