The Polish Ministry of Climate and the Environment issued the decisions-in-principle early in the day, Polish state news agency PAP reported.
The SMR nuclear facilities will be built in Włocławek, Stawy Monowskie, Stalowa Wola, Ostrołęka, Nowa Huta and Dąbrowa Górnicza, according to a statement.
The projects will be carried out by Orlen Synthos Green Energy (OSGE), a joint venture between Polish energy giant Orlen and chemicals company Synthos, the PAP news agency reported.
The six approved SMR nuclear units will feature "state-of-the-art GE Hitachi BWRX-300" technology, OSGE said on Thursday.
Orlen CEO Daniel Obajtek welcomed the government's decision, saying on social media that the SMR units would ensure "low-cost energy and heat" for Polish households.
OSGE plans to deploy Poland's first small reactors by 2030.
The Polish government has said it is aiming to speed up the phasing out of coal and plans to build renewable and nuclear power infrastructure to address challenges related to climate change and ensure stable power supplies, the Reuters news agency reported.
