"We confirm our nuclear energy project will use the reliable, safe technology of @WECNuclear," Morawiecki said on Twitter.Warsaw was also talking to French companies about the project."U.S. partnership on this project is advantageous for us all: we can address the climate crisis, strengthen European energy security, and deepen the U.S.-Poland strategic relationship," Vice President Kamala Harris said in a tweet.Warsaw had been seeking a partner to build 6-9 gigawatts (GW) of nuclear capacity and provide up to 49% equity financing for the project."We understand that the decision will be for the first three reactors and it is our expectation that Poland intends to eventually construct six AP1000 reactors from Westinghouse and will make a formal decision about the second set of three at a later date," the U.S. official said."
