UWFDM-1363 Application of CAD-Neutronics Coupling to Geometrically Complex Fusion Systems
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, and faster design iterations. DAG-MCNP has been applied to perform 3-D nuclear analysis for several fusion designs and demonstrated the ...
متن کاملStau-catalyzed Nuclear Fusion
We point out that the stau τ̃ may play a role of a catalyst for nuclear fusions if the stau is a long-lived particle as in the scenario of gravitino dark matter. In this letter, we consider dd fusion under the influence of τ̃ where the fusion is enhanced because of a short distance between the two deuterons. We find that one chain of the dd fusion may release an energy of O(10) GeV per stau. We d...
متن کاملTowards Nuclear Fusion
The outlook for controlled nuclear fusion has become much more complex than it appeared to be at least to the general public when the possibility of taming thermonuclear reactions for the production of useful power was optimistically mentioned at the 1955 Geneva conference on the peaceful uses of atomic energy. Indeed, it may now be impossible to r e capture the widespread excitement that follo...
متن کاملUWFDM-1368 Assessment of Using the Surface Source Approach in 3-D Neutronics of Fusion Systems
The accuracy of the results obtained using the surface source write/read feature of MCNP for toroidal fusion systems was assessed. Techniques that enhance the effectiveness of the surface source method were identified. Accurate results can be obtained for a specific component in a fusion system by either inserting the detailed component CAD geometry in the full model for the fusion system or ut...
متن کاملPhase III experimental results of JAERI /USDOE collaborative program on fusion neutronics
A pseudo-line D-T neutron source has been developed with new experimental techniques. This line source was applied in sophisticated neutronics experiments for an annular blanket arrangement simulating the tokamak geometry, as a new series in the JAERI/USDOE collaborative experimental program on fusion neutronics. The source characteristics of the present line source and the measurements for an ...
