The State Council on Thursday deliberated and preliminarily passed a five-year plan on nuclear security and radioactive contaminant treatment.

A long-term goal set for 2020 concerning the issue was also adopted.

According to the plan, China will adhere to a policy of "safety and quality first" and a basic principle of "prevention priority" for its strategy on the area.

China should raise the security levels of nuclear facilities and equipment for utilizing nuclear technologies while reducing security risks surrounding them, according to general objectives set in the plan and goal.

Capacities for preventing nuclear accidents, treating contaminants and responding to emergencies should be well developed to ensure people's health as well as the security of nuclear materials and the environment.

China should maintain and boost its level of nuclear security in the world, and continue to keep a sound radioactive environment by improving the prevention and control of radioactive contaminants, according to the plan.
