摘要

研究了仅使用电感驱动等离子体电流(和自举电流)的脉冲托卡马克反应堆的启动条件。采用包含等离子体功率和粒子平衡方程的零维(平均)模型,研究了等离子体启动的几个方面,包括:(1)启动路径的优化;(2)辅助启动加热功率与启动时间的权衡;(3)伏秒消耗;(4)工作点的热稳定性;(5)启动瞬态时转化器热流密度和温度的估算;(6)可用操作空间对H约束系数允许值的敏感性;(7)偏幂运算。

Start-up simulations of the PULSAR pulsed tokamak reactor
Start-up conditions are examined for a pulsed tokamak reactor that uses only inductively driven plasma current (and bootstrap current). A zero-dimensional (profile-averaged) model containing plasma power and particle balance equations is used to study several aspects of plasma start-up, including: (1) optimization of the start-up pathway; (2) tradeoffs of auxiliary start-up heating power versus start-up time; (3) volt-second consumption; (4) thermal stability of the operating point; (5) estimates of the divertor heat flux and temperature during the start-up transient; (6) the sensitivity of the available operating space to allowed values of the H confinement factor; and (7) partial-power operations.
