Description

The global Nuclear Steam Supply System (NSSS) market size is predicted to grow from US$ million in 2025 to US$ million in 2031; it is expected to grow at a CAGR of %from 2025 to 2031.

The impact of the latest U.S. tariff measures and the corresponding policy responses from countries worldwide on market competitiveness, regional economic performance, and supply chain configurations will be comprehensively evaluated in this report.

The Nuclear Steam Supply System (NSSS) is a critical component of a nuclear power plant responsible for converting the thermal energy produced by the nuclear reactor into steam, which is then delivered to the turbine-generator unit for electricity generation. The NSSS primarily includes key equipment such as the reactor core, control rods, reactor pressure vessel, coolant circulation system, and steam generators. Its core function is to release a large amount of heat through nuclear fission reactions, which is absorbed by the coolant (typically water or heavy water) to produce high-temperature and high-pressure steam that drives the turbine to generate electricity. The design and operation of the NSSS must strictly comply with safety regulations to prevent radioactive leakage and accidents, ensuring the safe and stable operation of the nuclear power plant.

As the "heart" of the nuclear power plant, the NSSS is not only vital to the efficient and stable nuclear reaction but also directly impacts the overall economic and environmental performance of the power generation system. By optimizing the structure and operational parameters of the NSSS, thermal efficiency can be improved, fuel consumption and waste emissions reduced, thus achieving the goals of green and low-carbon energy. Furthermore, with the advancement of nuclear technology, new NSSS designs increasingly incorporate advanced materials and automated control systems, enhancing the safety and automation levels of nuclear power plants. In summary, the NSSS serves as the crucial bridge connecting nuclear energy release and electricity generation, and its technological progress plays a significant role in promoting the sustainable development of the nuclear power industry.
