Case study on comparative assessment of nuclear and coal-fueled electricity generation options and strategy for nuclear power development in China

China, as other countries in the world, is seeking for a way of sustainable development. In energy/electricity field, nuclear power is one of electric energy options considering the Chinese capability of nuclear industry. The purpose of this study is to investigate the role of nuclear power in Chinese energy/electricity system in future by comprehensive assessment. The main conclusions obtained from this study are: (1) China will need a total generation capacity of 750 - 879 GW in 2020, which means new power units of 460 - 590 GW generation capacity will be built from 2001 to 2020. (2) the total amount of SO2 emission from power production will rise to 16 - 18 Mt in 2020, about 2.8 - 3.2 times of 1995, even if the measures to control SO2 emission are taken for all new coal units. (3) CO2 emission from electricity generation will reach 21 - 24 Gt in 2020. (4) the environmental impacts and health risks of coal-fired energy chain are greater than that of nuclear chain. The normalized health risk caused by coal chain is 20.12 deaths/GW·a but 4.63 deaths/GW·a by nuclear chain in China. (5) As estimated by experts, there will be a shortage of 200 GW in 2050 in China even if considering the maximum production of coal, the utilization of hydropower and renewable resource. Nuclear power is the only way to fill the gap between demand and supply
