Research Abstract

Purpose of the present study is to provide practical guideline for fusion reactor design and operation scenario with disruption avoidance. Regarding negative shear plasmas with transport barriers difficult to maintain, we have clarified characteristics of frequent disruptions, and provided a stable pathway to attain high-beta, high bootstrap current plasmas while taking a detour of the disruption avoidance.
First, a self-consistent simulation code was developed to model a transport improvement in accordance with the magnetic shear and a consequent formation of the plasma pressure and bootstrap current profiles. Physics models of disruption events such as thermal quench, associated current spike and vertical displacement were formulated. Additionally, physics model of the most common disruption, which has been frequently occurring in low-beta regime discharges, was provided for a guideline along which the disruptions can be avoided. A new neural-net predictor that can be used even for be … More ta-limit typed disruption normally observed without any of precursors and thus too hard to predict, was presented and verified by JT-60U experiments. In regard to high confinement plasmas fitting in with high bootstrap current, we presented steady-state, advanced operation scenarios, i.e., non-inductive current ramp-up and recharging of center solenoid current vigorously using the bootstrap current. Moreover, an innovative burning scenario was proposed to control the structure of transport barriers using a small inductive perturbation of externally applied electric field. Underlying mechanism of a beta-collapse with a regular intermittency observed in JT-60U negative shear discharge was clarified that "Return Current" induced by the NBCD turn-off underwent a spatial diffusion to modify the transport barrier, increasing in the stored energy that led to a MHD instability with a destruction profile localized around peripheral region of the negative shear plasma. The study has presented such the important knowledges useful for the sake of disruption avoidance operation scenarios. Less
