作为核反应堆的关键部件材料之一,核燃料的包壳服役性能严重制约核反应安全、性能和用途设计.新型不锈钢已成为未来先进反应堆核燃料用包壳的主要候选材料之一.本文概述国外不锈钢包壳材料研发进展,着重介绍我国在FeCrAl等新型包壳材料研制等方面取得的成果.面向未来不同需求的先进反应堆,这些自主研发的新型不锈钢包壳材料将为我国实现由核电大国向核电强国的转变提供有力支撑.
Influence of Active Control Strategy on the Motion Compensation at the Truncated Point of Mooring Li
The maximum predicting error of the commonly used passive truncated mooring system method may reach 30％ due to the difference of dynamic characteristics between the truncated and full-depth mooring line.In this paper,the experimental strategy called three
Collision Analysis Between Spudcan and Seabed During the Process of Jack-up Platform Lowering Jack-u
In the leg-lowering process,the offshore jack-up platform is in a floating state,and the spudcan may collide with the seabed due to the platform motion in waves,thereby threatening the safety and stability of the platform.This paper first analyzed the hyd
本文提出一种能够提供100 kWe电功率的新型海洋静默式热管反应堆(NUSTER-100)电源系统,可为无人水下潜航器提供低噪音、长寿期的电力供应.该电源系统采用双层壳体布置,主要由反应堆堆芯、热管、屏蔽体、温差发电器热电转换系统和螺旋式余热排出系统等子系统组成.在反应堆堆芯中,UO2燃料棒、慢化棒和钠热管矩形排列布置,以及热管从堆芯双端伸出,其冷凝段与温差发电器相连,实现热电转换.
