摘要

具有长寿命、非能动安全的小型核电站是核电发展的一个重要方向。本研究设计了一个小型核电站堆芯方案。该方案为池式钠冷快堆,采用移动反射层和堆内固定吸收体实现较长的堆芯寿期。进一步计算表明,该堆芯方案的寿期可达30年,功率分布合理,各种反应性系数为负值,控制方式的价值足够,满足设计要求。

Abstract

The small nuclear power plant enjoys advantages of long life and passive safety and is an important choice in the future nuclear power development. A conceptual core is designed for the small nuclear power plant. It is a pool-type fast reactor with sodium as coolant, the movable reflector and the fixed absorber as the reactivity control system for long-life. Further calculation results show that the life of the reactor could be as long as 30 years, with a reasonable power distribution, all the reactivity coefficients negative, enough reactivity control worth, and all parameters satisfy the design requirements.
