After four months of ups and downs, from the scorching summer into the late autumn, the maintenance support department Wanna lifted its mission and lived up to expectations. With the strong support of the department's leadership, it successfully completed the "401" and "203" overhaul of the Fuqing Nuclear Power Plant.
In view of the current gradual improvement of the operation standards of the nuclear power generating units, and considering the radio signals causing electromagnetic interference or other uncertain effects on the important equipment of the unit, Fuqing Nuclear Power has formulated management instructions for the use of radios, which also means that it is partially dependent on the radio command The lifting work of the crane must be transformed, and the whistle gesture will become the command leader.
As the so-called "three days without bombs, thorns grow by hand", daily leisure can not be neglected in practice. On November 16, 2018, the Wanner lifting project held another lifting operation operation using the overhaul gap period, focusing on the command whistle Gesture skills training exercises require uniform whistle, consistent gestures, and standardized standards.
The Service Section of the Maintenance Support Office attaches great importance to the theme of this practical operation. The owner came to the scene to teach carefully and spoke carefully.
A whistle, a powerful whistle, a signal, and a boost of morale; a wave, a clean, clear direction, coming and going. Simple sets of movements require long and repeated exercises to keep improving.
Wichiwana lifts to meet the requirements of nuclear power and complete work tasks for the purpose of strengthening operational skills and training elite soldiers with the goal of not fearing hardships, conviction and working hard.
Xingyue travels, the shutter is safely lifted out
The overhaul of 401 was underway in an orderly manner. Wanna lifted the team. The task was not light. It was busy inside and outside the nuclear island. At this stage, the burden of daily work is also heavy. During the operation of Unit 3, the secondary screen maintenance work has been successfully completed. After two days of emergency repairs after lifting in on the evening of August 19, 2018, the defects have been eliminated and two gates 3CFI001BU / 3CFI003BU need to be lifted.
On the evening of August 21, 2018, the 3PX A column sluices were lifted out at low tide levels. Only when the water level difference between the two sides of the sluices differed by one meter, the corresponding hydraulic pressure difference can meet the safety lifting requirements. The gate area is large, the weight is heavy, and the hoisting path is complicated. The attention of the hoisting personnel must be highly concentrated to ensure foolproofness.
"The moonlight is pouring, the fatigue is melting; the evening wind is light and fresh, and the decompression is fresh." At nine o'clock in the evening, the dream was right at that moment. Under the leadership of the Wanna lifting working group, with the corresponding lifting tools, stepped on the moonlight and rushed to the work site The work started as planned.
Before work, we will never be slack, and we will analyze them in detail. The equipment and tools will be checked one by one to ensure that they are intact and effective. The personnel will be confirmed to ensure that they are in good condition. The installation was completed and the measures were implemented. With the issuing of the command signal, the hoisting work officially started.
Take a rope ladder, hang a fall arrester, and a sling for a diver's drain. Find a center. The balance valve will slowly rise with the hook. A series of actions, which are familiar to members of this working group, are still prudent.
Uyghur leaders are concerned about the scene, and come to the site to supervise and guide them in order to escort the work smoothly and safely.
Every minute and every second, after five and a half hours of hard work, the sweat of the workers has soaked into the corners of the clothes, and the two gates of 3CFI001BU / 3CFI003BU were safely lifted out and smoothly fell into the gate storage pool.
Xingyue and Journey, this work was successfully completed, and it was inseparable from this lovely group of people who served nuclear power and performed their duties with due diligence; despite their dazzling aura, they were silently dedicated; they were so simple and extraordinary.

The service inspection is over. The preparation work for the suppression is started immediately. The lifting operation staff just sent their companions who participated in the service inspection and won the comrades who participated in the suppression work. A new round of nuclear island lifting operations started one after another. The hoisting of the internal components of the lower stack is completed, the hoisting of the internal components of the upper stack is completed, and the false top cover is hoisted, it is a sleepless night!
Next, the sluice hoisting, the guide column hoisting ... The hoisting operation staff will, as always, always accompany each other to complete each hoisting task entrusted by Fuqing Nuclear Power.
203 Overhaul progressed in an orderly manner, the lifting operation continued
Lifting Operation at the Maintenance Support Office
The 401 overhaul is not over yet, and the 203 overhaul has begun. The maintenance support office lifted the operation project, obeyed the command, obeyed the dispatch, immediately transferred from unit 4 to unit 2, and immediately participated in the 203 overhaul hoisting work.

Whether it's midnight or midnight, or dusk and dawn, the figure of the lifting operator always appears; from the tall gantry to the PX pump pit, the sweat and sincerity of the lifting operator are sprinkled everywhere.
PX seaside, dim lights, dwindling sea breeze, lifting operators and divers and drainage colleagues, all night long, under the gate 203 overhaul the first gate of the PX pump room.
The core of the nuclear island, night warfare, lifting operators are busy lifting the hoisting operation: recovery ring crane, lifting anti-flying object cover, lifting the air duct, entering the fake top cover, transporting the bolt stretching machine, lifting " D-shaped beams, the pressure vessel cover ... in one go.
