Erratum to “Proposal of a Deuterium-Deuterium Fusion Reactor Intended for a Large Power Plant” [World Journal of Nuclear Science and Technology Vol.14 No.1 2024] ()
Abstract
The original online version of this article (Lindecker, P. (2024) Proposal of a Deuterium-Deuterium Fusion Reactor Intended for a Large Power Plant. World Journal of Nuclear Science and Technology, 14, 1-58.
https://doi.org/10.4236/wjnst.2024.141001) unfortunately contains mistakes.
About the Reactivities
Reactivities were inaccurate. In Figure 1 below, more accurate reactivities are taken into account.
Figure 1. Reactivities of the D-D/D-T/D-He3 fusions. The abscissa is the equilibrium plasma energy (E_equi = Ecom) in keV and the ordinate is the reactivity in m3/s × 1E−23.
About Charge Exchanges between Ions and Gas Neutrals
It was supposed there would be permanent losses by charge exchanges on neutrals. This behavior exists at the beginning of the operation but disappears progressively as the fusion reactor wall is not in contact with the gas, so charge exchanges will not be considered. Therefore, the variables
are forced to 0.
Results and Conclusion
For a fusion radius of 4.5 m, the results are the following:
Kovrizhnikh scaling: nD = 15E19, E_inj = 610 keV, E_equi = 114 keV, Q = 1.80
Bohm scaling: nD = 18E19, E_inj = 380 keV, E_equi = 91 keV, Q = 1.64
These low mechanical gains Q greatly limit the advantage of this type of D-D reactor.
