On the morning of October 27th, China’s independent third-generation nuclear power “Hualong No. 1” mass-built the first unit-China National Nuclear Corporation Zhangzhou Nuclear Power Unit No. 1 inner dome successfully completed the hoisting workThis marks the unit’s full transition from the civil construction stage to the equipment installation stage, and also a solid step forward for the batch construction of “Hualong No. 1”.
The reporter learned that “Hualong No. 1” is one of the three generations of nuclear motors with the highest acceptance in the current nuclear power market, and it is also the “national name card” for China’s nuclear power to go global. The design life of the unit is 60 years, the reactor adopts 177 core design, and the core design refueling cycle is 18 months. The innovative use of “active and passive” combined safety system and double-layer containment technology meets international safety requirements. The highest safety standards are required.
According to Song Fengwei, General Manager and Deputy Secretary of the Party Committee of China National Nuclear and Guodian Zhangzhou Energy Co., Ltd., the inner dome hoisting is an important node in the construction of nuclear power projects. It is located on the top of the nuclear island. It is mainly to ensure the integrity and tightness of the reactor building and is critical for radioactive containment. effect.
In the early morning of the 27th, the hoisting work officially began. Following the order of the hoisting chief commander, the 3200-ton crane slowly lifted the inner dome off the ground. After a series of smooth movements, the inner dome reached the reactor building, then slowly descended and settled on the containment steel lining. .
It is reported that each unit of “Hualong No. 1” generates nearly 10 billion kWh per year, which can meet the annual production and domestic electricity demand of 1 million people in moderately developed countries; at the same time, it is equivalent to reducing standard coal consumption by 3.12 million tons and reducing carbon dioxide emissions by 816. Ten thousand tons, which is equivalent to more than 70 million trees for afforestation.
