本次反应堆压力容器的顺利到货为三澳核电项目2号机组后续核岛主设备安装及主管道焊接工作的开展提供了有力的支持和保障。

反应堆压力容器是核反应堆中的一个密闭容器，用于包容和支撑堆芯和堆内构件，并限制核反应在其内部进行，是核电站最核心的设备之一。

反应堆压力容器和其内堆芯、堆内构件共同组成了核电站的“心脏”，是核电站的动力之源。其工作原理是反应堆冷却剂(水)在主泵的推动下不断流经压力容器，带走其内堆芯产生的热量用于发电。

反应堆压力容器是圆柱状筒体，由顶盖组件、容器组件和紧固密封组件三部分组成，包括接管的容器最大直径为6.965m，总高度约为12.58m，总重量约为393吨。作为承载堆芯的容器，反应堆压力容器在保障核安全方面也发挥着重要作用。

The successful arrival of the reactor pressure vessel provides a strong support and guarantee for the follow-up installation of the main equipment of the nuclear island and the main pipeline welding of Unit 2 of the Sanao Nuclear Power Project.

The reactor pressure vessel is a closed vessel in a nuclear reactor, which is used to contain and support the core and inner components of the reactor, and limit the nuclear reaction inside it, and is one of the most core equipment of a nuclear power plant.

The reactor pressure vessel, its inner core and inner components constitute the "heart" of the nuclear power plant and are the power source of the nuclear power plant. The principle is that the reactor coolant (water) is constantly pushed by the main pump through the pressure vessel, taking away the heat generated by the core inside it for electricity generation.

The reactor pressure vessel is a cylindrical cylinder, which is composed of three parts: the top cover assembly, the container assembly and the tightening seal assembly. The maximum diameter of the container including the nozzle is 6.965m, the total height is about 12.58m, and the total weight is about 393 tons. As the vessel that carries the reactor core, the reactor pressure vessel also plays an important role in ensuring nuclear safety.
