This is the best summary I could come up with:

BEIJING, Dec 6 (Reuters) - (This Dec. 6 story has been corrected to change the timing and reason for NuScale's plant termination in paragraph 5)

China has started commercial operations at a new generation nuclear reactor that is the first of its kind in the world, state media said on Wednesday.

Compared with previous reactors, the fourth generation Shidaowan plant in China's northern Shandong province is designed to use fuel more efficiently and improve its economics, safety and environmental footprint as China turns to nuclear power to try to meet carbon emissions goals.

Xinhua news agency also said the 200 megawatt (MW) high-temperature, gas-cooled reactor (HTGCR) plant developed jointly by state-run utility Huaneng, Tsinghua University and China National Nuclear Corporation, uses a modular design.

Proponents say they can operate in remote locations and power traditionally hard-to-abate heavy industry sectors, but critics say they are too expensive.

China has also not signed a pledge by 20 countries at the COP28 climate conference taking place in Dubai to triple nuclear power capacity by 2050.
