目前,世界核电的发展处在一个困难时期。一条重要的原因是,日益严格的核安全要求使设计更加复杂,审批手续更加严格,导致核电的投资费用上升,因而发电成本也随之上升,使核能发电在相对其他燃料发电的市场竞争中优势减弱,或丧失优势。核电是否具有竞争力取决于它自身的成本和竞争对手两个因素。传统的竞争者有燃煤电站与燃气电站。尽管全球变暖的严重可能性有助于核电更好地参与竞争,因为化石 At present, the development of nuclear power in the world is in a difficult time. An important reason is that the increasingly stringent requirements of nuclear safety make the design more complicated and the examination and approval procedures more stringent, resulting in an increase in the investment cost of nuclear power, so the cost of power generation also increases, making nuclear power generation competitive with other fuel power generation market competitions Weaken, or lose advantage. Whether or not nuclear power is competitive depends on both its own cost and its competitors. Traditional competitors have coal-fired and gas-fired power plants. Although the serious possibility of global warming helps nuclear power to compete better because of fossils
