Fujian Yunxiao: The first main pump shell of the Zhangzhou Nuclear Power 2 main pump shell is smoothly lifted

A few days ago, Zhangzhou Nuclear Power No. 2 was lifted smoothly in the first part of the main pump shell. The entire lifting process was safe and stable, with controllable quality and controlling.

The first phase of the Zhangzhou nuclear power project adopts the "Hualong No. 1" nuclear power technology. Each unit has three main pump shells. There is a main pump shell in each ring. The only high -speed rotation equipment in the island is the main role of providing motivation for the cooling agent cycle and plays a vital role in the safe operation of nuclear reactors. The first main pump shell uses a 650 -ton track crane crane to introduce the main pump room from the top of the reactor plant.

In order to ensure that the main pump shell is introduced smoothly, the Zhangzhou nuclear power project construction management team fully draws the experience of hanging and installation of Zhangzhou Nuclear Power Unit 1, and compared with the traditional construction method, the innovation uses three -dimensional laser measurement technology to improve the use of leg adjustment. The processing accuracy of the pads is processed first before the main pump shell is lifted, which avoids the second suspension of the pump shell, optimizes the construction period, and reduces the occupation of crane resources. The project team introduced the main equipment of the unit 2 in actual actions, and continuously promoted the high -quality development of the Zhangzhou nuclear power engineering construction, laying an important foundation for the next step in welding of the main channel.
