摘要 基于行波堆的原理提出了径向步进倒料行波堆的概念,并将其与典型钠冷快堆的设计相结合,采用数值方法对由外向内的径向步进行波堆渐近稳态特性进行了研究。计算结果表明:渐近keff随倒料周期近似呈抛物线型分布,而渐近燃耗呈线性增长,满足临界条件的倒料周期中最大燃耗可达到53 at%;堆芯功率峰随着倒料周期的增长,从燃料卸出区(堆芯中心)向燃料导入区(堆芯外围)移动,功率峰因子随倒料周期先快速降低,后缓慢降低达到稳定。 Based on the mechanism of traveling wave reactor,a concept of radial step-shuffling traveling wave reactor is proposed.It is combined with the typical design of sodium-cooled fast reactors,the asymptotic characteristics of the inwards step-shuffling of which was studied numerically.The calculated results show that the asymptotic keff parabolically varies with the shuffling period,while the burn-up increases linearly.The highest burn-up achieved and satisfied the reactor critical condition is 53 at％.The power peak shifts from the fuel outlet side （core centre） to the fuel inlet side （core periphery）,and correspondingly the peaking factor firstly decreases along with the shuffling period dramatically,then slowly to a constant.
