美国的核电状况在电力市场放开后,为适应市场竞争,电力公司改善了运行维修措施,近10年间核电设备利用率提高了20%左右,利用率已达90%(见图1)。另外,对2003年核电与其它能源的成本进行了比较,核电成本是1.72美分/(kW.h),燃煤火电1.8美分/(kW.h)、天然气5.77美分/(kW.h)(见图2)。
After the U.S. nuclear power situation was liberalized in the electricity market, the power companies improved operation and maintenance measures to meet the market competition. Utilization rates of nuclear power plants increased by about 20% in the past 10 years and the utilization rate has reached 90% (see Figure 1). In addition, comparing the cost of nuclear power with other energy sources in 2003, the cost of nuclear power was 1.72 cents / kWh, coal fired power was 1.8 cents / kWh, natural gas was 5.77 cents / kW.h ) (See Figure 2).
