In 2020, two nuclear power standards set by the China National Nuclear Corporation (CNNC) became international standards. The standards are: the "Design Criteria for the Thermal Insulation of Reactor Coolant System Main Equipment and Piping of PWR Nuclear Power Plants" and the "Ice Plug Isolation of Piping In Nuclear Power Plant". The former was edited by CNNC's Nuclear Power Institute of China and Nuclear Industry Standardization Institute and the latter was edited by CNNC’s Qinshan Nuclear Power and Nuclear Industry Standardization Institute.

The "Design Criteria for the Thermal Insulation of Reactor Coolant System Main Equipment and Piping of PWR Nuclear Power Plants" marks China's first international nuclear power standard, created based on CNNC's Hualong One (HPR100) technology standard. It is an important symbol of the increasing international recognition of China’s independent nuclear power technology, and has great significance in terms of supporting HPR100 going global and strengthening the international influence of the country’s nuclear power sector. The “Ice Plug Isolation of Piping In Nuclear Power Plant” represents the second nuclear power international standard made by China in ISO (International Organization for Standardization).
