3.1 emergency plan It describes the work objectives, policies, and response philosophy of emergency response, as well as the organizations and functions for conducting a systematic, coordinated, and effective response. Responsibility, and the approved documents.

Note. This must be implemented through specific emergency execution procedures.

3.2 To ensure timely and effective public protection actions in the event of a nuclear power plant accident, protective measures were established and implemented in advance around the nuclear power plant. Areas with nuclear emergency response plans and preparedness.

Note. my country currently classifies emergency plans into two categories. plume emergency planning areas targeting plume irradiation pathways and ingestion emergency planning areas targeting ingestion irradiation pathways. Divide into districts.

3.3 emergency facilities Emergency response sites, systems, and equipment are set up in accordance with the principle of positive compatibility and relevant regulations.

3.4 For events or accidents that deviate from normal operating conditions at nuclear power plants, emergency states are classified into different categories based on their potential or actual impacts or consequences. The level.

Note. The emergency status levels of nuclear power plants are divided into emergency standby (U), plant emergency (A), site emergency (S), and off-site emergency (G). [Source: HAD002/08-2022, 2.1, modified]
