A top nuclear industry executive has called for priority to be given to nuclear power as China's power supply, ensuring that nuclear power plants are a primary source and their output is not adjusted to meet fluctuations in demand.

He Yu, chairman of China General Nuclear Power Corp, also suggests further construction and usage of a connected patchwork of grids across provinces and regions to ensure the consistent supply of the clean energy.

"Not given full play, nuclear reactors are constantly and sometimes consistently shut down like other power units, when the region's electric grid is at or beyond capacity," said He, who is attending the annual session of the National Committee of the Chinese People's Political Consultative Conference.
