With the global energy structure optimization, nuclear power is becoming increasingly important as a clean energy source. The domestic nuclear power industry chain has also formed a complete division of labor system, which is worth a deep understanding.

**Basic Components Layer**: This is the cornerstone of the entire industry chain. Pipe suppliers include Jiuli Special Materials and Longquan Shares; sealing solutions are provided by Zhongmi Holdings and Kelon Shares; the cable sector is dominated by Shangwei Shares, Wol Nuclear Materials, and Wanma Shares; special bearings are supported by Chongde Technology.

**Core Equipment Layer**: The most difficult and barrier-rich segment. Key technologies in pressure vessels are mastered by KeXin Electromechanical and China First Heavy Industries; generator sets are supplied by Dongfang Electric and Great Wall Electric; valve systems have multiple competitors including Jiangsu Shentong and China Nuclear Technology.

**Supporting and Operation**: Spent fuel processing involves specialized companies like Jingye Intelligent and Lanshi Heavy Equipment; long-term operation of nuclear power plants is undertaken by large state-owned enterprises such as China Nuclear Power and China General Nuclear; engineering construction is led by China Nuclear Construction and Huayin Electric Power.

The formation of this industry system reflects the full lifecycle demand from construction to operation of nuclear power. Understanding the industry chain also helps us better grasp investment opportunities in the energy sector.
