用于快堆主容器支撑的电磁阻尼隔震技术的研究

Research on the electromagnetic damping isolation technology applied to the main support of the fast reactor vessel

快堆核电站设计特点是高温薄壁,与压水堆的低温厚壁比起来,更需要考虑抗震设计。区别于传统的叠层橡胶和铅芯橡胶等隔震技术,本文提出了基于电磁阻尼原理的隔震技术。为了验证其有效性,制作了一个简易的电磁阻尼隔震支座,用作一个贮水容器的支撑。针对该水容器支撑系统在振动台上进行了抗震实验,验证了电磁阻尼隔震技术的有效性。

Fast reactor nuclear power plant design is characterized by high temperaturethin wall,compared with the low temperature-thick wall in pressurized water reactor,more need to consider the seismic design.Different from traditional seismic isolation techniques,such as lead core rubber and laminated rubber,A new isolation technology is proposed in this paper based on the principle of electromagnetic damping.In order to verify its effectiveness,we made a simple electromagnetic damping isolation bearing,used as a water container support.For this container support system,a seismic experiment is made on the vibration table to verify the effectiveness of electromagnetic damping isolation technology.
