Abstract

For the study of the alpha particles behavior in DT plasma the ‘Reacting Plasma Project’ (R-project in short) was initiated in 1981. The design study of the ‘R-tokamak’ was performed from 1981 to 1985, and evolved through three versions. The first version is based upon the usual tokamak and is similar to TFTR. The remote maintenance and dismantling however is considered very difficult. For the reduction of the residual radiation level the design of DT tokamak with aluminum alloy was conducted. It was found that hand-on maintenance after 1000 DT shots was feasible. Another effect of the aluminum alloy is the increase of the shell effect and stabilization of the variously shaped tokamak. The 3rd version tokamak with the extremely shaped cross-section (the crescent tokamak) is proposed for tokamak improvement (higher beta, better confinement and low radioactivity).

第一部分:r -托卡马克的概念设计

为了研究α粒子在DT等离子体中的行为，“反应等离子体计划”(简称r计划)于1981年启动。“r -托卡马克”的设计研究从1981年到1985年进行，并经过三个版本的发展。第一个版本是基于通常的托卡马克，类似于TFTR。然而，远程维护和拆卸被认为非常困难。为了降低残余辐射水平，进行了铝合金托卡马克的设计。发现在1000次DT射击后手工维护是可行的。铝合金的另一个作用是增加了壳体效应和各种形状托卡马克的稳定性。为了改进托卡马克(更高的β值，更好的约束和低放射性)，提出了具有极端形状截面的第三版托卡马克(新月形托卡马克)。
