Comment on 'Deuterium--tritium fusion reactors without external fusion breeding' by Eliezer et al

摘要

Inclusion of inverse Compton effects in the calculation ofdeuterium-deuterium burn under the extreme conditions considered by Eliezer etal. [Phys. Lett. A 243 (1998) 298] are shown to decrease the maximum burntemperature from about 300 keV to only 100--150 keV. This decrease is such thattritium breeding by the DD --> T + p reaction is not sufficient to replace thesmall amount of tritium that is initially added to the deuterium plasma inorder to trigger ignition at less than 10 keV.
