Karachi Nuclear Power Plant Successfully Hoisted

Pakistani local time at 10:16 on October 13th, China Nuclear Construction and Construction of the "Hualong 1" overseas first pile of Pakistani Nuclear Power Station No. 2 nuclear power plant in Karachi nuclear power plant successfully hoisted in place. The entire hoisting process has undergone a series of combined actions such as lifting, rotating and luffing, and the control is perfect, marking that the nuclear island No. 2 construction in Karachi Nuclear Power Station has been fully transferred to the equipment installation stage.

"Hualong No.1" is a three-generation nuclear power technology with independent innovation and complete intellectual property rights in China. It is a "national business card" for China's nuclear power to go to the world, and it is also a reference and reference for countries along the "One Belt and One Road." The successful lifting will greatly increase the confidence and potential for cooperation between China and the countries along the “One Belt and One Road” and enhance the competitiveness of “Hualong One” on the international stage. During the construction of the nuclear island of Karachi Nuclear Power Station No. 2 (K2 for short), nuclear Huaxing, China Nuclear Machinery and China National Nuclear Corporation of China Nuclear Construction & Construction Co., Ltd. overcame various difficulties and continuously pushed forward the progress of the project, which ensured the advancement of the major engineering nodes for the dome hoisting. achieve.

This is another major hoisting of the three generations of nuclear power technologies after Fuqing Nuclear Power Unit 5. The K2 nuclear island dome is the cap part of the steel lining of the containment vessel. Its external shape is a hemispherical shell with an inside radius of 23.4 meters. The hoisting load is 395 tons. It is one of the largest nuclear power plants with the heaviest and heaviest altitudes in the world. It is a high level of adjustment accuracy of equipment, allowing small errors; Second, the huge size of the equipment, the windward surface of the lifting process is very easy to cause equipment shaking; Third, the crane carrying more than 27 meters with a large span, increasing the lifting difficulty; Lifting height and docking accuracy is high, the allowable error of only 2 mm, the crane operating speed must be precise control. All units participating in the construction of China's nuclear construction will make concerted efforts to fully prepare and carefully organize them. They will always adhere to the principle of safety first and quality first, and successfully complete this lifting task.
