Nuclear power in the new energy,大连理工大学 2011,The use of nuclear energy,Nuclear submarine,Nuclear-powered aircraft carrier,Nuclear power plant,Hydrogen bomb,Marine nuclear power,Nuclear power,Atomic bomb,Nuclear weapons,Nuclear energy,Changes in energy consumption,the coal of 18th century,1920s-1960s,Coal,Renewable Energy,20th century,21st century,Natural gas,Oil,Solar Energy,Coal,Natural gas,Oil,New Energy,Nuclear energy,The worlds population over 60 million， Increase of more than 2 times the late 19th century， Energy consumption increased by 16 times.,Energy crisis,Fossil energy Reserves are limited！,Increasing energy consumption ！,Renewable Energy,water power,Wind Energy,Tidal power,Cant make full use of,Scale subject to environmental, seasonal and geographical constraints,Now Lack of development technology,solar energy,Nuclear energyInfinite Energy,Marine,核裂变 Nuclear fission,核聚变 Nuclear Fusion,铀、钍矿石,If all use, can be used for 24002800 years,氘（来自海水）、锂Deuterium (from sea), lithium,40亿万吨,2千多亿吨,If realized controllable fusion, those can use of billions of years,Uranium and thorium ores,Gas emissions of nuclear energy without pollution ！,Nuclear power is “the safest, cleanest and most cost-effective power resources “,Nuclear energy is a double-edged sword,辐射剂量大,陆地射线,the radiation of Life,电器辐射,建筑材料,天然辐射,医疗辐射,辐射剂量不大,核辐射,宇宙射线,花岗岩,核电站周围辐射剂量为0.01mSv/年 肺部透视一次辐射剂量为0.02mSv 拍一次胸片的照射剂量为0.12mSv 北京与欧洲之间乘飞机往返一次的辐射剂量为0.04毫希 允许标准：公众剂量不超过1mSv/年,Canadas Pickering nuclear power plant,Chinas Daya Bay Nuclear Power Station (Shenzhen),Nuclear power plant,Japan beauty coast nuclear plants,The peaceful use of nuclear energy,In 1951, the USA use a plutonium production reactor in the heat test generation, Britain, France, the Soviet Union and China, followed by the establishment of a number of nuclear power plants.,The current structure of the worlds energy,Nuclear power in the world energy consumed in 8 percent,Nuclear power in the world electric energy accounts for 17% (2000),Fossil fuels for 85% of total energy.,Fossil fuels for 30% of the total electrical energy. Oil for electricity generation is a waste.,The peaceful use of nuclear energy in the world,The peaceful use of nuclear energy in the world,There are over 441 nuclear power plants in the world, accounting for 17% of world electricity supply (2005),Share of the worlds nuclear power generation （2002）,Distribution of existing nuclear power plants in China,Chinas future nuclear power program,Planning （2007-2015） Improved second-generation unit, has started construction: 红沿河 (辽宁):建设61000MW,PWR; 阳江 (广东):建设61000MW, PWR; 方家山(浙江): 21000MW, PWR; 福清、宁德（福建）：分别建设61000MW, PWR； 昌江（海南） :建设2650MW, PWR； Three generations of nuclear power, has started construction: 三门 (浙江): 61250MW, PWR; 海阳 (山东): 61250MW, PWR; 台山（广东）:21750MW, PWR； Fourth-generation nuclear power: 荣成石岛湾 (山东): 120MW, 高温气冷堆； 三明（福建）：2800MW, BN-800快中子核反应堆。,The advantages and disadvantages of nuclear energy,核能优点： 1.核能发电不造成空气污染，不产生加重地球温室效应的二氧化碳。 2.核燃料体积小，运输与储存方便. 3.核能发电的成本中，燃料费用所占的比例较低. 4.核原料丰富。 核能缺点： 1.核能电厂会产生放射性废料。 2.核能发电厂热效率较低，热污染较严重。 3.核能电厂投资成本太大，电力公司的财务风险较高。 4.核能电厂选址受环境影响较大。 5.核电厂如果在事故中释放到外界环境，会对生态及民众造成伤害。综上所述：目前世界处在和平时代，发展是主流，为满足日益紧张的能源需求，虽然核能有其不足之处，但利大于弊，我们应该积极发展。,The advantages and disadvantages of nuclear energy,Advantages of nuclear energy: 1. Nuclear power does not cause air pollution and does not produce carbon dioxide which aggravates global warming. 2. Nuclear fuel has small size so it is easy for transportation and storage. 3. Fuel costs accounts for a lower proportion in the cost of nuclear power generation.4. Rich in nuclear material. Disadvantages of nuclear energy: 1. Nuclear power plant will produce radioactive waste. 2. Nuclear power plant has lower thermal efficiency and bad heat pollution. 3. Nuclear power plant needs large investment cost, the power company has higher financial risk. 4. The site of nuclear power plant is largely determined by environment. 5. The release into the external environment because of the accident will damage the ecology and people.,
