One-dimensional gamma-ray shielding analysis for EBT-P

Description: A one-dimensional scoping study was performed for the gamma ray shield of the ELMO Bumpy Torus proof-of-principle (EBT-P) device. The objective was to define appropriate shielding material and determine the required shielding thickness for EBT-P. The dose equivalent results as a function of the radiation shield thickness for different shielding options are presented. A sensitivity analysis for the pessimistic case is given. The recommended shielding option based on the performance and cost is d… more

Numerical model for radial transport in the ELMO Bumpy Torus

Description: Neutral and charged particle densities and temperatures are calculated as functions of radius for the toroidal plasma in the ELMO Bumpy Torus (EBT) experiment. Energy dependent ionization and charge-exchange rates, ambipolar diffusion, and self-consistent radial electric field profiles are included. Variation in magnetic field due to finite plasma pressure, effects of energetic electron rings, and transport due to drift waves and magnetic field errors are neglected. Diffusion is assumed to be n… more

One-dimensional gamma ray and photoneutron shielding calculations for the EBT-P

Description: One-dimensional radiation transport calculations have been performed to obtain estimates of the nuclear heat loads and biological dose rates due to bremsstrahlung gamma rays and photoneutrons in the EBT-P. The bremsstrahlung gamma rays arise because of electron impingement upon the magnetic coil assemblies and these gamma rays in turn produce photoneutrons through interactions in the high Z shielding materials. For a 1 MW electron power loss, /sup 238/U and tungsten coil shield thicknesses of a… more

ELMO Bumpy Torus Reactor (EBTR) reference design

Description: The goal of the ELMO Bumpy Torus Reactor (EBTR) study is the evaluation of the EBT confinement concept as the basis for development of a commercial fusion power reactor. A multidisciplinary, self-consistent treatment of EBT reactor scaling and design has been completed and a reference design (EBTR-48) has been developed. This design, based on a realistic plasma model and relatively conservative engineering parameters (i.e., 1 MW/m/sup 2/ neutron wall loading and a 7.3 T maximum toroidal field),… more
