摘要：
A traveling wave nuclear fission reactor, fuel assembly, and a method of controlling burnup therein. In a traveling wave nuclear fission reactor, a nuclear fission reactor fuel assembly comprises a plurality of nuclear fission fuel rods that are exposed to a deflagration wave burnfront that, in turn, travels through the fuel rods. The excess reactivity is controlled by a plurality of movable neutron absorber structures that are selectively inserted into and withdrawn from the fuel assembly in order to control the excess reactivity and thus the location, speed and shape of the burnfront. Controlling location, speed and shape of the burnfront manages neutron fluence seen by fuel assembly structural materials in order to reduce risk of temperature and irradiation damage to the structural materials.
摘要（中）：
行波核裂变反应堆，燃料组件，以及控制其中的燃耗的方法。 在行波核裂变反应堆中，核裂变反应堆燃料组件包括多个核裂变燃料棒，所述多个核裂变燃料棒暴露于爆燃波燃烧前沿，所述爆燃波燃烧前沿又通过燃料棒行进。 过量的反应性由多个可移动的中子吸收体结构控制，所述多个可移动的中子吸收体结构选择性地插入燃料组件和从燃料组件中取出，以便控制过度的反应性并因此控制燃烧前沿的位置，速度和形状。 通过控制燃烧场所的位置，速度和形状来管理燃料组件结构材料所见的中子注量，以降低温度和辐射损伤结构材料的风险。
