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 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.
