An integrated study of compact stellarator power plants, ARIES-CS, has been conducted to explore attractive configurations and define key research development (R&D) areas. The large size mass predicted by earlier plant studies had led cost projections much higher than those the advanced tokamak plant. As such, first major goal ARIES-CS was investigate if plants can be made comparable in variants while maintaining desirable properties. fusion core components would have complex shapes...
We are carrying out a multidisciplinary multi-institutional program to develop the scientific and technical basis for inertial fusion energy (IFE) based on laser drivers direct-drive targets. The key components developed as an integrated system, linking science, technology, final application of 1000-MWe pure-fusion power plant. science technologies here flexible enough be applied other size systems. justification this work is family target designs (simulations) that show direct drive has...
This study investigates the moderating role of firm size on relationship between managerial ownership and audit quality in Nigerian manufacturing sector. Using secondary data from 390 firm-year observations listed companies, logistic regression analysis was employed to examine hypothesized relationships. The findings reveal that positively influences quality, suggesting higher stakes align managers' interests with those shareholders, thereby promoting financial transparency accountability....
This paper presents an adaptive protection coordination scheme for optimal of DOCRs in interconnected power networks with the impact DG, used technique is Artificial Bee Colony (ABC). The adapts to system changes; new relays settings are obtained as generation-level or system-topology changes. developed applied on IEEE 30-bus test both single- and multi-DG existence where results shown discussed.
Within the ARIES-CS project, design activities have focused on developing first compact device that enhances attractiveness of stellarator as a power plant. The objectives this paper are to review nuclear elements received considerable attention during process and provide perspective their successful integration into final design. Among these radial build definition, well-optimized in-vessel components satisfy ARIES top-level requirements, carefully selected engineering parameters produce an...
The immense size and complex geometry of the ITER experimental fusion reactor require development special techniques that can accurately efficiently perform neutronics simulations with minimal human effort. This paper shows effect hybrid Monte Carlo (MC)/deterministic techniques—Consistent Adjoint Driven Importance Sampling (CADIS) Forward-Weighted CADIS (FW-CADIS)—in enhancing efficiency modeling demonstrates applicability coupling these methods computer-aided-design-based MC.

Fusion energy systems present increasingly significant computational challenges as they grow in size and complexity. Once constructed, ITER will be a full-size nuclear facility with highly complicated structures support systems, an array of scientific equipment close proximity to the neutron-emitting deuterium-tritium plasma. Characterization shutdown dose rate (SDDR) distributions caused by neutron activation these is important final design full-power operation device. This work summarizes...
Shutdown dose rate (SDDR) analysis requires (a) a neutron transport calculation to estimate flux fields, (b) an activation compute radionuclide inventories and associated photon sources, (c) final SDDR. In some applications, accurate full-scale Monte Carlo (MC) SDDR simulations are needed for very large systems with massive amounts of shielding materials. However, these impractical because space- energy-dependent fluxes throughout the structural materials is distribution radioisotopes...
An innovative computational tool (DAG-MCNP) has been developed for efficient and accurate 3-D nuclear analysis of geometrically complex fusion systems. Direct coupling with CAD models allows preserving the geometrical details, eliminating possible human error, faster design iterations. DAG-MCNP applied to perform several designs demonstrated ability generate high-fidelity high-resolution results that significantly improve process. This will be core a full CAD-based simulation predictive...

3-D neutronics analysis was performed for the baseline design of FDF. Two blanket concepts were considered; Dual Coolant Lead Lithium (DCLL), and Helium Cooled Ceramic Breeder (HCCB). A peak outboard neutron wall loading 2 MW/m2 a fluence 6 MW-yr/m2 can be achieved with 240 MW fusion power. The tritium breeding ratio is adequate both blankets. Modest magnet damage parameters obtained. However, it recommended that PF coil in divertor region moved vertically farther from mid-plane to allow...
