State Councilor Liu Yandong on Sunday stressed supervision and management efforts to ensure the "absolute safety" of a new nuclear power plant in east China's coastal city of Rongcheng.

Liu made the remarks during an inspection tour to the construction site of a Chinese-developed high-temperature gas-cooled reactor at Shidao Bay, the first of its kind in the country.

A key project out of the country's technological innovation efforts, the facility will become the world's first commercial fourth-generation nuclear power plant that incorporates upgraded safety features, the official said.

She called for better coordination among related government departments, enterprises, and research institutes to achieve more technological breakthroughs in the project.

Engineering, industrialization and internationalization levels of the project should be boosted in order to achieve technological progresses and support the nuclear power industry development as well, according to the official.

She said the project should be carried out in an active and steady manner to provide technological backup for promoting the development of clean energy in China.
