Practice and Thinking of Environmental Impact Assessment of Qinshan Nuclear Power Plant Operation License Extension Application

In view of the work related to the Operation License Extension (OLE) for the extended operation of Qinshan Nuclear Power Plant after the expiry of its operation license, the American license renewal (LR) and the long-term operation (LTO) system of the International Atomic Energy Agency (IAEA) are studied and analyzed. Based on the Technical Policy for Extension of Validity Period of Nuclear Power Plant Operation License (Trial) issued by the National Nuclear Safety Administration, the appropriateness, acceptability and compliance of environmental impact assessment of nuclear power plant extended operation are analyzed and studied, and the working methods and processes of OLE environmental impact assessment of nuclear power plants in China are put forward; Combined with the engineering practice experience of Qinshan NPP, the evaluation basis, evaluation criteria, data collection scope and source term optimization issues in the evaluation process are studied, and suggestions for the extended operation of nuclear power plants in China are put forward.
