1. Nuclear Power Fastener Market Summary

Nuclear power fasteners refer to high-performance mechanical parts used in nuclear power plants to connect and secure pressure-bearing boundaries or critical safety equipment. They are core components ensuring the structural integrity and operational safety of nuclear power plants. According to Chinese national mandatory standards, they specifically refer to bolts, screws, studs, and nuts used in pressurized water reactor nuclear power plants for nuclear safety levels 1, 2, and 3. These products must be manufactured using specific alloy steels or stainless steels, possessing extremely high strength, precision, and reliability to ensure long-term stable operation under harsh conditions. Their quality directly affects the functional execution of the nuclear power plant's safety system.

According to the latest research report from QYResearch, in 2024, global Nuclear Power Fastener production reached approximately 32,900 tons, with an average global market price of around US$21,000 per ton, the industry's gross profit margin is approximately 28%-60%. In terms of market size, the global Nuclear Power Fastener market size is projected to grow from USD 691 million in 2024 to USD 1 billion by 2031, at a CAGR of 5.60% during the forecast period.

4 Nuclear Power Fastener Industry Development Trends, Opportunities, Obstacles and Industry Barriers
Development Trends:

1. Enhanced Safety and Intelligent Upgrades. The core trend is to improve reliability under extreme operating conditions and integrate intelligent monitoring. Future products will integrate microsensors to monitor fastener preload, vibration, and stress corrosion in real time, enabling predictive maintenance. Design will focus more on developing material models resistant to multiaxial fatigue and high-dose radiation, shifting from "passive fastening" to "active sensing and health management," providing key data nodes for digital nuclear power plants and significantly improving safety and operational efficiency.

2. Customized Design Adapting to Advanced Reactor Types. To meet the compact design and higher operating parameter requirements of small modular reactors and fourth-generation reactors, fasteners are evolving towards highly customized, multifunctional integration. This includes developing connection schemes suitable for non-traditional layouts, new material systems resistant to higher temperatures and corrosion from special cooling media, and standardized pre-installed connection systems to meet the needs of rapid modular construction.

3. Full Life Cycle Management and Material Innovation. The focus is shifting from "manufacturing products" to "providing full life cycle solutions," emphasizing the long-term stability of materials throughout the reactor's 60-80 year lifespan. Development trends include developing steels and alloys with lower activation and better resistance to radiation embrittlement; applying additive manufacturing technology to produce special fasteners with complex internal cooling structures; and establishing life prediction and aging management models based on digital twins to ensure fastener performance is synchronized with reactor life.

Development Opportunities:

1. Global Nuclear Power Resurgence and New Project Construction. Driven by energy security and carbon neutrality goals, the world is entering a new round of nuclear power construction. New projects in China, Europe, the Middle East, and Belt and Road countries are directly increasing the market for high-end fasteners. For example, the mass construction of third-generation reactors such as Hualong One, VVER-1200, and EPR, as well as demonstration projects for future fourth-generation reactors, all require a large number of high-performance fasteners that meet the latest safety standards, providing a clear long-term order window for leading technology companies.

2. Service Extension and Upgrading of Aging Units. Many operating nuclear power units worldwide are applying for extensions of their operating licenses to 60 or even 80 years, creating a huge demand for replacement and upgrades. Aging fasteners in existing equipment need to be replaced according to the latest standards, and new, higher-performance fasteners are often used during upgrades to improve safety margins. This creates a continuous service market for companies with certification and retrofitting experience, with stable demand and considerable profits.

3. Opportunities for Supply Chain Localization and Domestic Substitution. For supply chain security reasons, many countries are promoting the localization of key nuclear power components. This presents an opportunity for leading domestic manufacturers to substitute imports, particularly in the non-core but critical auxiliary system fastener sector. By acquiring domestic project experience and international certifications, companies can gradually penetrate from auxiliary systems to main equipment systems and leverage cost and service advantages to enter the international supply chain, achieving a leap from "follower" to "running alongside."

Hindering Factors:

1. Stringent Certification Cycles and High Costs: Entering the nuclear power market requires rigorous certification from ASME NCA, NQA-1, and national nuclear safety authorities, a process that takes 3-5 years and is extremely expensive. Simultaneously, fluctuating raw material prices and the small-batch, multi-variety production model lead to high manufacturing costs. Under the overall cost reduction demands of nuclear power projects, suppliers face the dual pressures of extremely high quality requirements and fierce price competition, limiting profit margins.

2. Technological Barriers and Talent Bottlenecks: Nuclear power fasteners involve multiple disciplines, requiring solutions to challenges in materials science, mechanics, radiation damage, and long-life reliability. There is a shortage of multidisciplinary talent with experience in nuclear-grade product design, process engineering, and quality control. Furthermore, the application of next-generation welding, coating, and testing technologies requires continuous R&D investment and testing resources, posing a significant technological challenge to small and medium-sized enterprises and hindering the overall innovation speed of the industry.

3. Supply Chain Vulnerability and Geopolitical Risks: The nuclear power supply chain is highly globalized, with key links such as special metallurgy and precision machining concentrated in a few countries and companies. Geopolitical conflicts, trade barriers, or unforeseen events can easily lead to disruptions in raw material supplies, logistical disruptions, or restrictions on technology transfer. Furthermore, nuclear safety requirements necessitate extremely stringent supply chain audits; any change in a second-tier supplier can trigger lengthy recertification processes, increasing the complexity and uncertainty of supply chain management.

Barriers:

1. Qualification and Certification Barriers: Nuclear safety regulations require all fasteners used in safety-related systems to be designed, manufactured, and inspected based on an extremely stringent quality assurance system. Companies must establish and continuously operate a complete nuclear quality assurance system, obtain ASME "N" or "NPT" stamp authorization, and pass multiple source audits by owners and regulatory agencies. This process involves huge investment and a long cycle, and a major quality problem could lead to qualification revocation, constituting the highest entry barrier.

2. Technology and Experience Barriers: Products need to undergo long-term performance testing in simulated nuclear environments, and data accumulation often takes more than ten years. The operating conditions vary greatly between different reactor types and different parts; design know-how and failure databases are core company secrets. Products without actual project verification and long-term operational feedback are difficult to gain the trust of design institutes and owners, making it almost impossible for new entrants to compete in core areas.

3. Market and Reputation Barriers: Nuclear power plant owners and EPC contractors are extremely conservative, preferring suppliers with a long history of good operating performance and successful cooperation. Supply chain relationships are highly stable, forming a closed loop of "cooperation - project performance - deeper cooperation." Even if a new supplier has the qualifications and technology, it needs to slowly enter the market from the non-security level or spare parts market, and spend many years accumulating the performance of its first core system order. During this period, it requires continuous investment with limited returns, which constitutes a strong market inertia barrier.
