Zoomlion Achieves a New Breakthrough in Nuclear Construction
Author: Zoomlion Date: 2015-01-26
A major technological breakthrough in China's major nuclear power plant system and the safe development of nuclear power have been named as energy priorities in 2015, after nuclear power has been in the spotlight this winter. Attracting as much market attention as nuclear power has been the significant progress in construction of nuclear power plants.
Recently, the world's most powerful crawler crane, Zoomlion's ZCC3200NP, made its debut at the Tianwan Nuclear Power Plant in Jiangsu, where it successfully lifted the world's heaviest nuclear containment dome into place, marking the first successful use of a domestic 3,000-ton crawler crane in the field of nuclear power.
Zoomlion Achieves First Lift in Nuclear Power Station Construction
Tianwan Nuclear Power Station is the first nuclear power project to be approved in China since the Fukushima nuclear disaster in Japan, and reactors 3 and 4 are being built thanks to deepened cooperation between China and Russia following successful cooperation during the first phase of construction. Zoomlion's participation in the hoisting project involved lifting the containment dome into place during the construction of Reactor 3 during the second phase of construction of the Tianwan Nuclear Power Station, which was also the first time a nuclear containment dome had been hoisted anywhere in the world since the Japanese earthquake in 2011.
Although lifting reactor domes in the construction of nuclear power plants is not a new feat domestically, the Tianwan plant's dome was no ordinary dome, as it is currently the largest in the world in terms of its external dimensions, weight and radius. The dome has a diameter of 44 meters, is 22 meters high, has a total weight of 476.4 tons, has a lifting radius of 105.4 meters and is 56.15 meters high when in position.
The difficulty of the lifting operation lies in the fact that the dome's shell is just 6 mm thick and is easily deformed by gravity, which means the lifting points must be designed to ensure that its distortion is within an acceptable range. What's more, the ultra-large crane is operating within a confined space, placing even more stringent requirements on the lifting equipment.
Given the enormity and complexity of the task, it is little wonder the construction company chose to use Zoomlion's ZCC3200NP large-tonnage crawler crane. The ZCC3200NP was mainly developed for use in the construction of China's third-generation nuclear power plants, and it is currently the world's most powerful and technologically advanced large-tonnage crawler crane. It is also the first domestically produced 3,000-ton crawler crane to go into assembly, complete testing and be put on the market.
Key Technological Breakthroughs in Nuclear Power Raise the Stakes and Improve the Market
With the continued construction of nuclear power plants in China, the ZCC3200NP, which has already passed the highest level of technical appraisals in the field of hoisting machinery, will soon have more opportunities to show what it can do.
It was recently announced that a research and development project on a "million-kilowatt pressurized water reactor with a control rod system" led by China Guangdong Nuclear Power Group has already been given the green light by a team of experts at the Ministry of Science and Technology. This indicates that domestic enterprises have already fully grasped the application of the key technology of control rod drive systems with 12- and 14-feet fuel assemblies and have achieved a major step toward the safe development of nuclear power.
In addition, at the 2015 National Energy Work Conference held at the end of last year, "safe development of nuclear power" was named a priority for energy work in 2015. It was recommended that on the basis of adopting the highest international nuclear safety standards and ensuring safety, construction should be started on nuclear power projects with ripe conditions; key breakthroughs are needed in nuclear equipment research and development; and protection should be given to, and in-depth demonstrations carried out at, a number of preferred nuclear power plant sites.
Chairman of the China National Nuclear Corporation, Sun Qin, has great expectations for nuclear power station construction. He believes that China is in the process of making the leap from second-generation to third-generation nuclear power technology. After 2016, as technology such as AP1000 continues to mature, nuclear power will undergo major development, with six nuclear power stations forecast to be built per year over the next decade as a result of RMB 70 billion of annual investment in nuclear power plant construction. This will also usher in greater development opportunities for Zoomlion.
Not only that, in 2014, Chinese Premier Li Keqiang promoted the sale of Chinese nuclear power technology abroad and encouraged Zoomlion and other Chinese equipment manufacturing enterprises to go global. Public reports show that since late last year, when national leaders began actively marketing China's nuclear power capabilities, Chinese nuclear power companies have successively signed project agreements with countries including the United Kingdom, Romania, Pakistan and Argentina.
Zoomlion's Layout Guiding the Industry's Future Configuration
The ZCC3200NP lived up to expectations. In just over one hour, the colossal 3,000-ton crawler crane completed its first task, making it the first domestic crane of its size to be used in the construction of a nuclear power project, and its speed, stability and safety earned it universal praise.
Zoomlion's first lifting operation in the field of nuclear power is no accident, however.
Zoomlion's predecessor, the Changsha Construction Machinery Research Institute under the former Ministry of Construction, was the cradle of Chinese hoisting machinery. Zoomlion has always been the standard-setter of Chinese tower crane technology and used its strength in technology and forward-looking layout to remain at the top of the industry worldwide.
In 2009, relying on its strength in technology, and with China's third-generation nuclear power firmly in its sights, Zoomlion began research and development on the ZCC3200NP. From completing feasibility studies to successfully completing a fully configured one-off boom raise, to receiving a manufacturing license for 3,000-ton crawler cranes, Zoomlion has painstakingly completed each step in the process of delivering the ZCC3200NP to its debut at the Tianwan Nuclear Power Plant.
Now that the strength of China's nuclear power industry has been combined with Zoomlion, China's premier brand in hoisting machinery, what positive changes will result as China's equipment manufacturing industry looks to go global? We will have to wait and see.
