OSGE SMR Program (BWRX-300) – first power plant in Włocławek

in preparationstage: permits

The program to build Poland's first small modular nuclear power plant (SMR) using BWRX-300 technology, carried out in Włocławek by Orlen Synthos Green Energy (OSGE), in which Orlen and Synthos Green Energy each hold a 50 percent stake. The project envisages building up to six reactors on the Włocławek site; the first stage assumes commissioning at least two units with a combined capacity of approximately 0.6 GW by 2035. The special-purpose company BWRX-300 Włocławek obtained a fundamental decision from the Minister of Energy, and environmental and siting studies are currently underway ahead of submitting an application for a construction permit.

Significance

This is intended to be Europe's first power plant based on BWRX-300 reactors, making the project a significant element of plans to decarbonize and diversify the national power system. The creation of a source of stable, zero-emission energy and heat in Włocławek is part of the development of nuclear power in Poland and the building of national competencies in the area of small modular reactors.

Independence is counted the same way the gate that admits a record counts it: subdomains and titles from one publisher are a single voice, Wikipedia is zero. That is why the number is lower than the number of links. Three is the minimum.
