The supply and demand of uranium resources both domestically and abroad is firstly analyzed in the paper. The supply can still meet the demand in the short run, but the risk of shortage may exist in the long run. Moreover, the lack oJuranium resources will exist globally no matter at present or in the future. ThereJore, the main.factor restraining the nuclear power development in China is the short supply of uranium. Finally, recommendations are put Jorward such as strengthening the exploration and production of domestic uranium, cooperating with foreign enterprises in the exploration of uraniam mines, building the reserves, and proactively developing the fourth generation of nuclear power technology and so on.展开更多

The nuclear fission energy is available now, with proven reactors, such as advanced LWR （light water reactors）. Nuclear strategy in this paper outlines a proposal to replace all coal power plants （without carbon and capture storage system） with nuclear power plants in the period 2025-2065. Assuming once through advanced LWR technology, one would need nuclear capacity of 1,600 GW to replace coal power plants in that period. Corresponding reduction of emission would amount to 11.8 Gt of CO2. This energy strategy would reduce carbon emission by approximately 22% in the year 2065 and would be covered by projected uranium resources. An estimation of replacement costs showed that future carbon tax has a considerable potential to offset higher costs of nuclear replacement power.展开更多

文摘The Chinese government has set ambitious goals for the development of nuclear power, which is under the risks from uranium supply shortage. The supply and demand of uranium resources both domestically and abroad is firstly analyzed in the paper. The supply can still meet the demand in the short run, but the risk of shortage may exist in the long run. Moreover, the lack oJuranium resources will exist globally no matter at present or in the future. ThereJore, the main.factor restraining the nuclear power development in China is the short supply of uranium. Finally, recommendations are put Jorward such as strengthening the exploration and production of domestic uranium, cooperating with foreign enterprises in the exploration of uraniam mines, building the reserves, and proactively developing the fourth generation of nuclear power technology and so on.
