Transformers for Nuclear Power

As the global energy system shifts toward low-carbon generation, nuclear power is emerging with renewed relevance. Its ability to deliver consistent, carbon-free electricity makes it a valuable complement to intermittent renewables like solar and wind. New technologies are expanding the possibilities for nuclear deployment — from remote communities to industrial clusters. But realizing the full potential of modern nuclear energy requires more than innovation at the reactor level. It depends on a reliable and resilient supporting infrastructure.

Partner with Hitachi Energy

With over 50 years of nuclear project experience and more than 250 nuclear-grade transformer deliveries trusted by 70% of the world’s nuclear power operators, Hitachi Energy stands out as the partner of choice — combining deep domain expertise with a proven track record of delivering safe, resilient, and digitally enabled solutions tailored for the nuclear applications.

Needs & Challenges

Reliability Nuclear power plants are design to run in continue operation for long periods. Reliable products and suppliers are fundamental to keep the power plant running. Conventional nuclear plants for 18-24 months. SMR would be even for 60 months or more depending the technology.

Energy Transition Nuclear power will be critical to meeting growing electricity demand while also achieving decarbonization goals and reduce the dependencee on fossil fuels. Recent projections suggest that global nuclear capacity could increase to 890 GWe by 2050, almost double current capacity

Safety Managing threats from natural disasters, terrorism, cyber attacks or any malfunctioning equipment. Safety is top priority on any nuclear facility, to keep the environmental and human integrity dur to the impact consequences.

Supply Chain The rising of SMR´s will add additional pressure on supply chain for electrical components including transformers. References and experience in nuclear business are fundamental pillars to understand customer needs including dynamic allocation and nuclear safety culture.

Transformers play a quiet but essential role in that system. They step up and stabilize the electricity generated at nuclear sites, ensuring it can be transmitted safely over long distances. In an era defined by electrification and digitalization, these components must meet new expectations — combining nuclear-grade safety with long-term availability, digital intelligence, and scalability. As nuclear generation evolves, so too must the technologies that move its energy to where it’s needed most.

Whitepaper: The life cycle assessment and sustainability of generator step-up transformers

The study assesses the impact of the life cycle and sustainability of generating step-up transformers (GSUs). It analyses the global warming potential (GWP) of GSUs in different power generation scenarios: Nuclear, wind, photovoltaic and combined cycle. The study identifies which phases of the lifecycle has the greatest impact and proposes strategies aimed at reducing the carbon footprint, increasing circularity and improving safety.
