Empirical scaling laws and extrapolation to Helias reactors
Empirical scalings of energy confinement are used to predict ignition parameters in a Helias reactor. These scaling laws are: Lackner-Gottardi scaling (LGS), international stellarator scaling (ISS95) and international stellarator scaling with W-7 data only (ISS95(W7)). For comparison, tokamak scaling laws (ITER89 and ELMYH92y) are also taken into account. The results show that ISS95 yields a confinement time which is too small for ignition. LGS and ISS95(W7), however, are sufficient for ignition. An isotope factor or any improvement by H-mode confinement are not taken into account. The Helias reactor requires a confinement time of 1.7 s.
