Four firms sign a BWRX-300 framework at the UN sidelines
Serguey Asael Shinder2 min readFour companies have signed a memorandum of understanding on deploying BWRX-300 small modular reactors in Europe: Poland's SGE, the United States' GE Vernova, Japan's Hitachi and South Korea's Samsung C&T. World Nuclear News reports it at https://www.world-nuclear-news.org/articles/ge-vernova-hitachi-sge-and-samsung-ct-sign-mou-on-bwrx-300s-in-europe.
The signing took place on the sidelines of the United Nations General Assembly, during the Atlantic Council Nuclear Energy Policy Summit. The document establishes what the parties describe as a framework for cooperation on market development and commercial opportunities. SGE is already developing projects for a fleet of these reactors, notably in Poland and the United Kingdom.
The announcement links the MOU to a memorandum of cooperation on SMR deployment in third countries signed at this year's NATO summit by the foreign ministers of the United States, Japan and South Korea; the US State Department is quoted describing the industry agreement as a concrete follow-on.
What it means
The interesting structure is the pairing of a government memorandum with an industry one. States signed an intent about third countries; four companies then signed the vehicle that could act on it. Neither document builds anything, but together they answer the question a buyer asks first, which is not "does the reactor work" but "who will still be here in fifteen years to supply it".
Samsung C&T's presence is the part worth noting. A reactor vendor plus a construction house with major infrastructure experience is a different offer from a reactor vendor alone - and for SMRs, where the case rests on repeatable build cost rather than on unit output, construction capability is closer to the core of the product than the reactor design is.
⚠️ An MOU is a framework, not an order. No site, no unit count, no schedule and no money appear in what was announced, and the fleet projects mentioned are SGE's existing development work rather than anything this document commits.
