UWFDM-1134 Nuclear Analysis of the FIRE Ignition Device

نویسنده

  • M. E. Sawan
چکیده

Neutronics and activation calculations have been performed for the FIRE design with different first wall design options. Modest values of nuclear heating occur in the machine components. Magnet insulators that have radiation tolerance to 150 MGy should be used. The operational schedule allows for decay of short-lived radionuclides between pulses resulting in low levels of activity and decay heat at shutdown. Additional shielding is provided in midplane ports and at the top of the machine to allow for hands-on maintenance of ex-vessel components.

UWFDM-1111 Initial Nuclear Performance Evaluation of the FIRE Ignition Device

Nuclear parameters for the FIRE ignition device have been determined. These parameters included nuclear heating, radiation damage, and magnet insulator dose. Nuclear heating values as high as ~40 W/cm are deposited in the invessel components. End-of-life damage is very low and will not limit the lifetime of the chamber components. The peak end-of-life insulator dose is 1.5x10 Rads. The total nu...

UWFDM-1162 Nuclear Considerations for FIRE

Nuclear analyses have been performed for the baseline design of the Fusion Ignition Research Experiment (FIRE). Nuclear heating, structural radiation damage, and magnet insulator dose were evaluated. Critical issues requiring additional R&D effort include low-temperature embrittlement of copper and identifying insulators that can handle a dose as high as 1.5x10 Rads under the FIRE load conditio...

A Fire Ignition Model and Its Application for Estimating Loss due to Damage of the Urban Gas Network in an Earthquake

Damage of the urban gas network due to an earthquake can cause much loss including fire-induced loss to infrastructure and loss due to interruption of gas service and repairing or replacing of network elements. In this paper, a new fire ignition model is proposed and applied to a conventional semi-probabilistic model for estimating various losses due to damage of an urban gas network in an eart...

Safety Analysis of Spent Fuel Transportation Cask of Bushehr Nuclear Power Plant through the Passing of Fire Tunnel with ANSYS®10.0

The spent fuel assemblies (FAs) of Bushehr Nuclear Power Plant are planed to be transported by TK-13 casks. Each spent fuel transportation cask holds 12 spent FAs and has a thick steel container to provide shielding. The calculations have been performed for FAs with burn ups of 60 MWd/kg and a 3-years cooling period. The ANSYS®10.0 general finite element analysis package was se...
