Our extensive experience in providing materials to the nuclear industry positions us as a trusted partner for some of the most demanding applications in this field.

 

Product quality and safety is at the forefront of how we operate. Steel Dynamics is the first metal distributor in the UK to achieve the ISO 19443 accreditation, which reinforces our position as the number one supplier of stainless steel to the Nuclear industry. It demonstrates our commitment to health & safety, and provides our customers with complete reassurance that all our materials meet the highest possible standards.

 

Applications for the Nuclear Industry

Steel Dynamics offers a broad portfolio of stainless steel products designed to meet the nuclear industry's exacting standards. From mainstream stainless steel profiles to custom specifications for critical components, the company ensures a reliable supply chain for the following key applications:

 

Nuclear Reactor Pressure Vessels (RPVs)

Reactor pressure vessels are some of the most critical components in nuclear power plants. These vessels house the reactor core and must withstand extreme temperatures, high pressure and radiation exposure.

 

In the UK’s Advanced Gas-Cooled Reactor (AGR) nuclear plants, Steel Dynamics supplies high-strength stainless steel for the reactor pressure vessel, which must endure continuous exposure to heat, radiation and high-pressure steam over the plant's operational lifetime.

 

Steam Generators

Steam generators in nuclear power plants transfer heat from the reactor core to the water, creating steam that drives the turbines. These components operate under high temperatures and must resist corrosion from both the reactor coolant and the steam.

 

In Pressurised Water Reactors (PWRs), Steel Dynamics provides stainless steel for steam generator tubes, ensuring resistance to the aggressive environment of superheated steam and reactor coolant. This material maintains structural integrity, reducing the risk of leaks or failures.

 

Spent Fuel Storage

Nuclear waste and spent fuel must be stored safely for decades or even centuries. Stainless steel plays a vital role in the construction of spent fuel storage containers and casks, where its corrosion resistance ensures the safe containment of radioactive materials.

 

Steel Dynamics provides corrosion-resistant stainless steel for dry cask storage containers used to store spent nuclear fuel at decommissioned power plants. These containers must remain secure for extended periods, often stored outdoors in varying environmental conditions.

 

Primary and Secondary Cooling Systems

Cooling systems are essential for regulating the temperature of nuclear reactors, preventing overheating and ensuring safe operation. The primary coolant, which circulates through the reactor, and the secondary coolant, which transfers heat to the steam generators, both require piping and components made from corrosion-resistant materials.

 

In the UK’s Hinkley Point C nuclear power plant, stainless steel provided by Steel Dynamics is used for piping, pumps and heat exchangers in these cooling systems, ensuring efficient heat transfer while resisting corrosion and mechanical wear for the long-term reliability and safety of the plant.

 

Nuclear Decommissioning and Waste Processing

As older nuclear plants are decommissioned, there is a growing need for materials that can handle radioactive waste processing and storage. Steel Dynamics supplies stainless steel for waste containment systems, ensuring the safe and long-term storage of radioactive waste.

 

During the decommissioning of the UK’s Sellafield nuclear site, Steel Dynamics supplied stainless steel for waste storage containers and processing equipment used to safely handle and store radioactive materials during site clean-up and dismantling operations.

 

Conclusion

Steel Dynamics plays a pivotal role in supplying high-performance stainless steel to the nuclear industry, supporting the sector's stringent safety, reliability, and durability requirements. From reactor pressure vessels to spent fuel storage and decommissioning, our specialist stainless steel products are integral to the safe operation and long-term sustainability of nuclear facilities.

 

By combining decades of experience, technical expertise, and a commitment to innovation, Steel Dynamics is a trusted partner for nuclear projects in the UK and beyond, helping to power the future of clean energy.
