Description
This dataset represents the average power generation situation of pressurized water reactor (PWR) nuclear power plants in China. Its data are obtained by weighted aggregation of the production datasets of Jiangsu, Zhejiang, Fujian, Shandong and other provinces (regions, municipalities). For the production datasets of specific regions, key processes such as nuclear fuel consumption, radioactive effluent discharge, solid waste generation and water treatment are considered at the inventory level, and the technical service life is 60 years. The nuclear fuel consumption is estimated by a back-calculation method based on the amount of spent fuel generated; the radioactive discharges include gaseous effluents (inert gases, iodine isotopes, etc.) and liquid effluents (tritium, carbon-14, etc.), while the generation of low- and intermediate-level radioactive waste and the material consumption during water treatment are also accounted for; all data are standardized to form a representative regional average. The data are mainly sourced from official statistics and announcement documents.
Activity Description
The system boundary covers the entire operation and maintenance stage of nuclear power plants, including energy release from nuclear fission, water cooling, and discharges.
Process Description
The product is grid-connected power in kWh, with a voltage level of ≥35 kV.

Technology comment
Pressurized water reactor refers to a nuclear reactor that uses light water (that is, ordinary purified water) as coolant and moderator, and the water remains liquid in the reactor. It adopts a primary and secondary loop design. The radioactive primary loop is separated from the secondary loop. The radioactive primary loop coolant will not enter the secondary loop to pollute the steam turbine. The unit is easy to operate and maintain. It is the main model of my country's nuclear power plants.
