“…The study assumes the same level of technology development ("achievable in 20 years") as in the ARIES-I study (Ref. 22). The thicknesses, compositions, average mass densities, and unit costs for the En'stwall/blanket/reflector assembly and the neutron shielding are the same as,those for ARIES-I.…”

Stellarators have significant operational advantages over tokamaks as ignited steady-state reactors because stellarators have no dangerous disruptions and no need for continuous current &"ive or power recirculated to the plasma, both easing the first wall, blanket, and shield design; less severe constraints on the plasma parameters and profiles; and better access for maintenance. This study shows that a reactor based on the torsatron configuration (a stellarator variant) could also have up to double the mass utilization efficiency (MUE) and a significantly lower cost of electricity (COE) than a conventional tokamak reactor (ARIES-I) for a range of assumptions. Torsatron reactors can have much smaller coil systems than tokamak reactors because the coils are closer to the plasma and they have a smaller cross section (higher average current density because of the lower magnetic field). The reactor optimization approach and the costing and component models are those used in the current stage of the ARIES-I tokamak reactor study. Typical reactor parameters for a 1-GW(e) Compact Torsatron reactor example are major radius RO = 6.6-8.8 m, on-axis magnetic field B0 = 4.8-7.5 T, Bmax (on coils) = 16 T, MUE = 140-210 kW(e)/tonne, and COE (in constant 1990 dollars) = 67-79 mill/kW(e)h. The results are relatively sensitive to assumptions on the level of confinement improvement and the blanket thickness under the inboard half of the helical windings but relatively insensitive to other assumptions.

“…This paper adopts the cost expressions and unit values used in Ref. 22, in which the ARIES-I reactor was recosted using the rules that evolved during the ARIES-III study, with some recent (through May 1992) improvements. 23 The COE estimated for the 1-GW(e) ARIES-I tokamak reactor has evolved from 69 mill/kW(e)h in 1988 dollars (Ref.…”

This paper presents work using the capabilities of two TEM with in-situ ion irradiation facilities: Microscope and Ion Accelerator for Materials Investigation (MIAMI) at to study the nucleation and growth of He bubbles in silicon carbide (SiC) and to carry out an investigation into bubble behaviour at high temperatures and under displacing irradiation. Preliminary results on bubble nucleation and growth during He irradiation of SiC are presented together with results from a simultaneous anneal and highenergy heavy-ion irradiation of samples containing He bubbles. The displacing irradiation is observed to impede He bubble growth resulting in smaller bubbles than those obtained from an anneal alone. A tentative interpretation of these observations is presented.
