Who we are
Nordic Nuclear Energy AB (NNE) is a Nordic nuclear energy company developing next-generation nuclear technologies for a fossil-free and reliable energy system. Building on decades of Nordic experience in reactor design and industrial delivery, the company operates within established regulatory frameworks.
NNE’s current commercial focus is BWR-N, an evolutionary Nordic boiling water reactor designed for large-scale, fossil-free baseload power and adapted to Nordic regulatory requirements and industrial needs.
NNE’s objective is to develop BWR-N as a series-built reactor platform. The company’s initial target is four reactors, with two in Sweden and two in Finland, reflecting the economics of series deployment over one-off construction.
What BWR-N is
BWR-N stands for Boiling Water Reactor Nordic. It is an evolutionary BWR developed from Swedish reactor design and decades of accumulated operational experience. The design builds on the proven Nordic reactor tradition represented by Forsmark 3 and Oskarshamn 3.
This means that key technical principles, safety philosophy, and system solutions are already well understood – including by licensing and regulatory authorities. Modern safety features are incorporated to cope with even the rarest accidents such as core melt or aircraft crash.
In spring 2025, NNE initiated a pre-licensing dialogue with SSM and STUK (the Swedish and Finnish Radiation Safety Authorities) regarding licensing in Sweden and Finland.
Our Story
In the 1970s, Sweden responded to an energy crisis by building a stable, affordable and safe electricity system. Within fifteen years, eleven reactors were delivered in Sweden and Finland, creating a lasting Nordic legacy in reactor design, industrial delivery and operational excellence.
BWR-N builds on that legacy. It is an evolutionary boiling water reactor designed for today’s requirements on safety, reliability and large-scale fossil-free power generation.
History shows that it can be done again.
