This paper built a combined heat and power（CHP） dispatch model for wind-CHP system with solid heat storage device（SHS） aiming at minimizing system coal consumption, and set system demand-supply balance and units＇ operation conditions as the operation constraints. Furthermore, robust stochastic optimization theory was used to describe wind power output uncertainty. The simulation result showed that SHS increased CHP peak-valley shifting capability and reduced abandoned wind rate from 12% to 6%, and reduced 5% coal consumption, compared with the original system operation by flexible charging electric power and heating. The payback period of employing SHS in wind-CHP system is far shorter than SHS expected service life.

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 *** 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.
