Group 1 - The International Atomic Energy Agency (IAEA) has raised its nuclear power installation expectations for five consecutive years, expanding the "Triple Nuclear Declaration" from 22 countries to 33 countries and large non-nuclear enterprises, with a target of 1200 GW by 2050 [1][2] - The World Nuclear Association (WNA) predicts that global nuclear power installations could reach 1363 GW by 2050 based on current government targets, and potentially 1428 GW when considering proposed projects [1][2] - The revival of nuclear energy is highly certain at the government level, with a decrease in countries abandoning nuclear power, such as Germany, and significant developments in the U.S., Japan, and Russia [2] Group 2 - Factors contributing to the exceeding expectations for nuclear energy include multi-domain applications such as nuclear heating and hydrogen production [2] - The inherent safety and sustainability of fourth-generation nuclear power is supported by natural physical laws that ensure safety without external operations, and fast reactors can increase uranium resource utilization from 0.5% to 60-70% [2] - Recent developments in the U.S. include the signing of an executive order to reform nuclear reactor testing, with a goal to construct at least three advanced reactors by July 4, 2026 [2] Group 3 - In China, the first fourth-generation high-temperature gas-cooled reactor is expected to be operational in 2023, with significant advancements in sodium-cooled fast reactors anticipated by 2025 [2] - Shanghai Electric (601727) has a significant advantage in the supply of nuclear island equipment for high-temperature gas-cooled reactors, while Zhejiang Fu Holding (002266) is expanding its offerings in the control rod drive mechanism and main pump supply for sodium-cooled fast reactors [3] - Investment recommendations include focusing on Shanghai Electric, Dongfang Electric (600875), Harbin Electric, and Zhejiang Fu Holding [3]
