Video Documentary: Elastic Support & Damping Systems in Gösgen Nuclear Power Plant
The Gösgen Nuclear Power Plant in Switzerland provides a good example of long-term use of elastic support and damping systems for various key components in nuclear power generating plants.
During the operation of machines such as turbines, pumps and other rotating equipment, disturbing vibrations can affect other parts in the nuclear power plant. Vibration isolation technologies suppress these disturbing effects and can be installed as elastic support systems. These technologies can also be integrated for special protection of the installed safety systems to protect from external loads such as earthquakes, aircraft impact scenarios or the risk of possible foundation settlements.
Together with the team in Gösgen, we took a look at the elastic support systems that have been installed over the past decades and representatives of the operator gave some statements about their corresponding experience.
Power Plant Structures & Equipment – Elastic Support
Seismic Control of a Steam Turbine Foundation
Elastic support of JPL power plant turbine in Seoni, India.
The site is located near village Barela -Gorakhpur, Tehsil Ghansore of Seoni District. JPL currently has 600 MW thermal capacity fully operational and 660 MW under implementation. The plant is generating power on commercial basis. With a total mass of about 28,750 tons, the turbine house of this power station is approx. 95 m long, 46 m wide and 39-m high.
In 2010, GERB was consulted by the operator of the power plant directly and asked for a vibration control solution. We started supporting the owner as well as the structural designer already at an early project phase. Particular focus was placed on the high earthquake input to be taken into account. Starting with our explanations of similar projects, there were intensive consultations with the project participants about possible optimization of the turbine building. In addition to developing project-specific spring and damper elements, the substructure underneath the elastic support system was discussed in detail.
Vibration Isolation of Heat Pumps on Residential Building
Upgrade of Elastomeric Bearings to GERB Spring Elements
Residential buildings are way more sesnitive in case of vibrations because of the individual lifestyle and sentiments of each resident. Whereas a certain level of vibration stress is normal in an industrial environment, this does not apply to residential buildings, where people‘s quality of life is severely affected. Disturbing excitations need to be isolated to protect the living environment.
In this case, the vibrations originate from the operation of heat pumps on the roof of a residential building. The initial solution to isolate the vibrations was not successful and made the house uninhabitable. GERB was consulted about the problem in April 2022. After some measurements, a suitable solution was already installed in May.
粘滞阻尼器减少石化厂管道系统振动
中东地区的一家石化公司找到了隔而固，希望帮助他们解决胺装置的管道振动问题。
由于振动水平超过了允许限度，共有4个单元需要解决（参见图 1）。客户的内部流程研究显示，管道中存在段塞流，引起了无法消除的内力。考虑到管道大口径 (36”) 、垂直运行长以及大多数支承物都连接在压力容器上等限制，修改管道路线或现有支承物是不可行的。隔而固管道阻尼器是解决此类问题的好方法，因为它具有良好的改造特性，而且具有很强的减振性能。目标是将第一个安装单元的 6 号和 7 号位置的分类等级从“堪忧”改善到“可接受”（其他单元的分类等级类似但略有不同）。
