Meanwhile, 13 percent oppose the plan and 12 percent are undecided, according to the study by pollster CBOS.
The poll was carried out from November 7 to 17 on a sample of 1,038 respondents, Polish state news agency PAP reported.
Poland last month approved plans to build its first nuclear power plant using technology from US company Westinghouse Nuclear.
The USD 20 billion plant will be built "in the north of the country," Prime Minister Mateusz Morawiecki told a news conference at the time.
Morawiecki announced that the government had also greenlighted a Polish-South Korean project to build a nuclear power plant at Pątnów in western Poland.
Poland's state-run Energy Group (PGE) and energy producer ZE PAK last month signed a letter of intent with South Korea’s state-owned energy company KHNP on developing plans for the construction of that facility, according to officials.
The Polish foreign minister said in November that the choice of a foreign partner for the construction of Poland’s third planned nuclear power plant remained "open."
Poland’s Prime Minister Mateusz Morawiecki has said the country plans to build a total of “six reactors in three nuclear power plants.”
The first unit of a new Polish nuclear power plant is expected to be put into operation in 2033, under a long-term energy policy adopted by the government last year.
Then further units are expected to come online every two to three years until a total of six, with a combined capacity of up to 9 GW, are in service, the PAP news agency has reported.
