Reforms, in view of a comparative party-state model, become the instruments of self-reproduction and self-destruction of party-state power. The specific patterns of power distribution imply different development and transformation paths through different instruments of self-reproduction. This approach also points to the structural and dynamic background of the differences in the location, sequence, speed and political conditions of reforms during the operation and transformation of party-states. In view of the model the paper points to the inconsistencies that emerge in the comparative reform literature concerning the evaluation and strategies of reforms disconnected from their systemic-structural context.

The paper shows that the three-phase bridge convertor can be represented in the steady state by a circuit model. Circuit models are deduced for naturally commutated and forced commutated convertors. Steady state power rectification, inversion, the d.c. link, and variable frequency motor control are described.

Abstract One of the major challenges for the GW-class Chinese Fusion Engineering Testing Reactor (CFETR) is to efficiently handle huge power fluxes on plasma-facing components (PFCs), especially the divertor targets. This work investigates the effects of two candidate radiation impurity species, argon (Ar) and neon (Ne), with two different divertor geometries (baseline and long leg divertor geometry) on the reduction of steady-state power load to divertor targets in CFETR by using the SOLPS-ITER code package with full drifts and kinetic description of neutrals. The modeling results show clearly that increasing the seeding rate of Ar or Ne with fixed fueling gas D2 injection rate reduces the target electron temperature and heat flux density for the baseline divertor geometry, which can be reduced further by higher D2 injection rate. With a high impurity seeding rate, partial detachment with steady-state power load at the divertor target below the engineering limit of 10 MWm-2 is demonstrated. In addition, the radiation efficiency for Ar is better than that for Ne. Increasing the divertor leg length reduces the electron temperature and heat load at the targets. This modeling, therefore, suggests that a long leg divertor design with Ar seeding impurity is appropriate to meet the CFETR divertor requirements.
