Plans for Poland’s first nuclear power plant continue to progress
Building Poland’s nuclear program from the ground up is progressing with Poland’s first nuclear power plant project: three AP1000 reactors at the Choczewo site in the voivodeship of Pomerania.
The Polish state-owned utility Polskie Elektrownie Jądrowe has announced some recent developments over the past few months, including turbine island procurement and strengthened engagement with domestic financial institutions, in addition to new data from the country’s Energy Ministry showing record‑high public acceptance, which demonstrates growing nuclear momentum in the country.
