(Reuters) – China may have to put the brakes on the construction of nuclear power plants to ensure the plants are safe, the country's top energy planning official told reporters on Sunday.
Zhang Guobao, head of the National Energy Administration, warned of signs of "improper" and "too fast" development of nuclear power in some regions.
China had previously set a goal of 40 gigawatts of nuclear power capacity by 2020, which would entail building about two reactors a year.
"We'd rather move slower and achieve less than incur potential safety concerns in terms of nuclear energy," Zhang told reporters on the sidelines of the Sino-U.S. Energy Summit.
Of renewable energy sources, hydropower accounts for the biggest share, or 6 percent of China's total primary energy mix. Nuclear makes up about 0.6 percent and other sources such as wind power and solar power account for a trivial proportion, Zhang said.
