UWFDM-829 The Impact of Proton-Induced Activation on the Level of Radioactivity in D-3He Fusion Reactors
نویسندگان
چکیده
Experimental radionuclide production cross sections have been collected for protons with energy similar to those protons produced in a D-3He fusion reactor. Proton energy-dependent cross sections (Ep < 14.7 MeV) were used along with the proton stopping data of Anderson and Ziegler to produce a proton-induced thick-target radionuclide activation yields library. In its present form, the library contains thick-target yield data for 164 radioactive isotopes. The library has been used in an activation analysis study aimed at investigating the effect of proton-induced activity on the total level of radioactivity generated in Apollo-L2 (a D-3He tokamak fusion power reactor). Because protons have a short range in solid targets, their effect has been noticed only within the first wall of the reactor. Results showed that while neutroninduced specific activity generated in the reactor Tenelon first wall is 8.1 × 107 Ci/m3, proton-induced specific activity only amounted to 6.37 × 105 Ci/m3.

UWFDM-951 Assessment of First Wall Lifetime in D-3He and D-T Reactors with Impact on Reactor Availability
The neutron yield in a D-He reactor is much lower than that in a D-T reactor of equivalent power. Therefore, the rate of neutron damage and gas production in the first wall of D-He reactors is lower by more than an order of magnitude. Whereas different structural materials proposed for use in commercial fusion reactors will last the reactor lifetime of 30 full power years in a D-He reactor, fre...

It is expected that advanced fuels be employed in the second generation of nuclear fusion reactors. Theoretical calculations show that in such a fuel, a high plasma temperature about 100 keV is a requisite for reaction rate improvement of nuclear fusion. However, creating such a temporal condition requires a more powerful driver than we have today. Here, introducing an optimal fuel configuratio...
متن کاملEconomic Analysis of Advanced Fuel Fusion Reactors and Derivation of Scaling Law for COE∗)
Social acceptance of fusion reactors depends largely on their economic viability. To investigate this issue, we estimate and compare the cost of electricity (COE) among D-T, D-3He, and D-D fusion reactors. Three types of confinement systems are evaluated: the tokamak reactor (TR), the spherical tokamak reactor (STR), and helical reactor (HR). For each reactor type, COE parameter surveys are per...
متن کاملUWFDM-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...
