福岛核电站英文演讲稿 篇一:福岛核事故分析-英文 How Is Japan's Nuclear Disaster Different 王小亮 学号: 班级: Abstract:There are some key differences that set the current Fukushima situation apart from the 1979 Three Mile Island emergency and the 1986 Chernobyl nuclear disaster. In terms of reactor type, Japan's Fukushima Daiichi nuclear power complex is made up of six boiling-water reactors, or BWRs—a type of "Light Water Reactor." Whereas the Three Mile Island used another type of Light Water Reactor known as a pressurized-water reactor, or PWR. In aPWR, the water is kept under pressure. This means the temperature can be higher than the boiling point of water without generating asignificant amount steam (a less efficient coolant). So the reactor core operates at ahigher temperature in these systems, and heat can be transferred more efficiently. Boiling-water reactors operate at lower temperatures, and they “ ” , , “ ” 、 “ ” , , , 按 照 三 个 贴 近 的 要 求 紧 紧 围 绕 全 区 中 心 工 作 深 入 开 展 平 安 区 充 分 就 业 区 创 建 活 动 着 力 提 高 市 民 素 质 弘 扬 城 市 文 明 精 神 为 实 现 全 区 城 市 统 筹
