%X North-china will be threatened by water resource crisis in 2050, with a deficit of 520×108m3. Besides economizing on water (342×108m3) and long-distance water intake (63×108m3), we should pay greater attention to family planning (100×108m3), the remaining deficit (15×108m3) may be settled by seawater desalination for the main purpose of pulling economic growth. Among several large-scale desalination technologies, reverse osmosis is of the most outstanding quality than multiple stage flash and multiple effect distillation, for its low investment cost, low operating expense, low energy consumption, mild corrosion, long service life, easy repair, repaid development of large-scale desalination technology. As to energy consumption of desalination along the coast in north china, there are no more potentialities to exploit for hydroelectricity. Thermal power consumes much more resources with long load distance of coal and severe environmental pollution, while its carbon emission is 60-160 times as much as that of nuclear power. Experiences in France, Russia and Japan indicate that nuclear power cost account for only 80%-90% of thermal power cost under 10% discount rate. So nuclear power should play a very important role in the future. The energy consumption of nuclear desalination by can be solved by building 3 nuclear power plants each with the capacity of 2×600MW. By doing so we can optimize power source structure of north china, which will strongly ensure economic fast growth in north china. Nuclear desalination by reverse osmosis can bring up with a series of new economic growth points while protecting environment, saving the resources of coal, oil, gas etc, making use of ocean resources, with profound sustainable development significance. In addition to being not as good as reverse osmosis in terms of several technological and economic targets, nuclear desalination by multiple effect distillation can not do better than by reverse osmosis economically due to the reactor type and capacity limitation of 200MW nuclear heating reactor.
