National security as defined in the National Security Law does not include nuclear security.

The contents of China's nuclear safety concept are: paying equal attention to development and safety, rights and obligations, independence and cooperation, and treating symptoms and root causes.

In order to make better use of nuclear energy and achieve greater development, mankind must meet all kinds of nuclear safety challenges and maintain the safety of nuclear materials and nuclear facilities. Strengthening nuclear safety is a continuous process. We should adhere to the rational, coordinated and gradual concept of nuclear safety and bring the nuclear safety process into the track of healthy and sustainable development.
