BWRX-300 abroad: Poland and the UK
Where it stands: The BWRX-300's export story outside North America: Polish capital and siting toward a Pątnów plant, and a UK joint venture to operate a fleet - the deployment model financed and organized abroad.
- 2026-10-02/03 (export ecosystem): Polish capital enters — PLN 500M (~$128M, source-provided) from Polish entrepreneurs into SGE's BWRX- 300 fleet plans for Poland, the UK and Europe (WNN) — private local money attaching weeks after the Sep 23 GEVH+SGE+Samsung C&T MoU. The fleet-deployment model now has a financing layer beyond vendor balance sheets.
- 2026-10-15 (Poland siting layer): SGE and ZE Pak have agreed to establish a joint venture to develop a nuclear plant at Pątnów with up to six GE Hitachi BWRX-300 SMRs (WNN, ~8:39 AM ET Oct 15 — world-nuclear-news.org/articles). Development: the Sep 23 GEVH+SGE+Samsung C&T MoU and the Oct 2 PLN 500M (~$128M) fleet financing now gain a named Polish site, a unit count, and a JV counterparty. Watch: JV structure and ownership split, the Polish regulatory path, schedule vs the ledgered 2036/2040 large-reactor programme dates.
- 2026-10-16 (
outlet~4:25 AM ET, second outlet): Energynews.pro reports the SGE–ZE PAK joint venture for six BWRX-300 SMRs totalling 1,800 MWe at Pątnów (energynews.pro/en). Development: a second independent confirmation of the JV already recorded Oct 15 via WNN; no new ownership split, regulatory, or schedule detail in capture. Watch items unchanged: JV structure and ownership split, Polish regulatory path, schedule vs the ledgered 2036/2040 national-programme dates. - 2026-10-22 (~8:02 AM ET, WNN — world-nuclear-news.org/articles): SGE's UK-based project company and Origin Nuclear, a subsidiary of Ontario Power Generation, have signed a letter of intent to establish a joint venture for the future operation of a planned fleet of 14 BWRX-300 SMRs in the UK. Development: the Sep 23, 2026 GE Vernova Hitachi + SGE + Samsung C&T MoU (European BWRX-300 deployment, the UK among the named geographies) and the Oct 15 SGE–ZE PAK Polish JV now gain an operator-side instrument — OPG, the utility behind the Darlington BWRX-300 (construction began May 2025), contributing operating capability to a cross-border fleet. LOI-grade: the JV is not yet established; no site list, schedule, or staffing detail in coverage. Article does not mention TVA. Watch: JV execution and ownership split, the named sites/utility behind the 14 units, the UK licensing path, and whether OPG's operating model extends to the Polish or other European fleets.
