8月16日11时38分、14时39分，海阳核电4号机组两台安注箱分别吊装就位，整个吊装过程安全、有序、可控。

安注箱总容积为56.6立方米，水容积为48.1立方米，净重约36.65吨，设计寿命60年，属于低合金钢球形容器，能在机组出现冷却剂丧失事故(LOCA)等异常工况时，为堆芯提供硼水进行冷却。每台机组共有两台安注箱，分别安装于核岛反应堆厂房11206和11207房间。

此次吊装就位标志着4号核岛反应堆厂房开始进入设备安装阶段，也为4号核岛反应堆厂房102平台形成创造了有利条件。

At 11:38 and 14:39 on August 16, two safety injection boxes of Unit 4 of Haiyang Nuclear Power Plant were respectively hoisted into place, and the whole hoisting process was safe, orderly and controllable.

The total volume of the safety injection tank is 56.6 cubic meters, the water volume is 48.1 cubic meters, the net weight is about 36.65 tons, and the design life is 60 years. It is a low-alloy steel spherical container, which can provide boron water for the core to cool when the unit has abnormal conditions such as loss of coolant accident (LOCA). Each unit has a total of two safety injection tanks, respectively installed in the nuclear island reactor building room 11206 and 11207.

The hoisting and installation marks the beginning of the equipment installation stage of the No. 4 nuclear island reactor building, and also creates favorable conditions for the formation of the 102 platform of the No. 4 nuclear island reactor building.
