一、核能的英语
核能的英语:nuclear energy
原子能又称“核能”。即原子核发生变化时释放的能量,如重核裂变和轻核聚变时所释放的巨大能量。
放射性同位素放出的射线在医疗卫生、食品保鲜等方面的应用也是原子能应用的重要方面。在发现原子能以前,人类只知道世界上有机械能,如汽车运动的动能;有化学能,如燃烧酒精转变为二氧化碳气体和水放出热能;有电能,当电流通过电炉丝以后,会发出热和光等。这些能量的释放,都不会改变物质的质量,只会改变能量的形式。
在50多年前,科学家发现铀-235原子核在吸收一个中子以后能分裂,同时放出2—3个中子和大量的能量,放出的能量比化学反应中释放出的能量大得多,这就是核裂变能,也就是我们所说的核能。
二、核电厂的英语是什么
核电站[hé diàn zhàn]
nuclear power station; nuclear power plant

It's sheer folly to build nuclear power stations in a country that has dozens of earthquakes every year.
3
核电站造价高昂,虽然运转费用低廉。
Nuclear plants are expensive to build, though cheap to operate
4
作为一个核能发电的长期支持者,她在今年的福岛核电站事故之后关闭了七个反应堆。

5

三、介绍核电站的好处英语资料
一、简介:
核电站(nuclear power plant)是利用核裂变(Nuclear Fission)或核聚变(Nuclear Fusion)反应所释放的的能量产生电能的发电厂。目前商业运转中的核能发电厂都是利用核裂变反应而发电。核电站一般分为两部分:利用原子核裂变生产蒸汽的核岛(包括反应堆装置和一回路系统)和利用蒸汽发电的常规岛(包括汽轮发电机系统),使用的燃料一般是放射性重金属:铀、钚。
二、工作特点:
一)优点
1.核能发电不像化石燃料发电那样排放巨量的污染物质到大气中,因此核能发电不会造成空气污染。
2.核能发电不会产生加重地球温室效应的二氧化碳。
3.核能发电所使用的铀燃料,除了发电外,没有其他的用途。
4.核燃料能量密度比起化石燃料高上几百万倍,故核能电厂所使用的燃料体积小,运输与储存都很方便,一座1000百万瓦的核能电厂一年只需30吨的铀燃料,一航次的飞机就可以完成运送。
5.核能发电的成本中,燃料费用所占的比例较低,核能发电的成本较不易受到国际经济情势影响,故发电成本较其他发电方法为稳定。
二)缺点
1.核能电厂会产生高低阶放射性废料,或者是使用过之核燃料,虽然所占体积不大,但因具有放射线,故必须慎重处理,且需面对相当大的政治困扰。
2.核能发电厂热效率较低,因而比一般化石燃料电厂排放更多废热到环境里,故核能电厂的热污染较严重。
3.核能电厂投资成本太大,电力公司的财务风险较高。
4.核能电厂较不适宜做尖峰、离峰之随载运转。
5.兴建核电厂较易引发政治歧见纷争。
6.核电厂的反应器内有大量的放射性物质,如果在事故中释放到外界环境,会对生态及民众造成伤害。 7.现阶段的核能发电,仍然会产生很多放射性废物,其中尤以高放废物的处理及处置为国际性难题。
三、英语观点:
一)反对方
We are for to close the Nuclear power station, I’d like to illustratemy view in the following 4 aspects.
1, Danger
As far as I know, building a nuclear power station cost hugeinvestments at the beginning of the project, and it cost a long time to get thecost back,
Until now, china has already got 13 nuclear power stations, and another27 are in the process. But these 13 nuclear power stations only provide 1% ofthe total amount of the electricity. Besides, most of these stations are builtin the east part of China. However, more than 3/4 of the whole population livein this part. Once it went out of control, present technology can’t ensure anabsolute safety, so the consequence is inconceivable. What’s more, the damageit has made is a kind of long term effect and can’t be repaired.
As Yangtze river is suffering from a drought, the inner land hasn’t gotenough water to support the nuclear power stations. However, a station needsmore than 2 times the water a normal coal station need to produce the same amountof water. Once it is short of water, the system can’t control the temperature,then the tragedy in Fudao will appear again.
2, Supervision
The great danger of it is not the station itself, but the supervision.For now, so many government officials embezzle money and are engaged in corruptpractices, what they think is one thing: money. In such circumstance, how canyou make sure that the building process of the stations is under a fairsupervision. If not, how can you guarantee the quality of the nuclear powerstations.
3, Waste
Though we are lack in many resources, do you know how many resourceshave we wasted every year? In western countries, even the temperature achieved30, they won’t turn on the air-conditioner. However, in our country, even it isonly 26, the air-conditioner will be running all day long in our governmentbuildings, let alone such waste in many other places. As a result, what weshould do is to decline the waste of different kinds of energy resources.
4, Solar Energy
After the nuclear power explosion in Japan, Germany and Swiss hasdecided to close the nuclear power stations before 2034. In Germany, solarenergy provides more than 55% of the whole electricity, and it also produceelectricity by wind energy and water energy. Why can’t we also develop other typesof power stations as solar energy power station?
In one word, Nuclear Power Station has got tremendous hidden danger,endangering the whole nation and other parts of the world, so they should beclosed as soon as possible.
How soon will you take action after its explosion
Where to build
二)支持方:
Before built the nuclear power stations, many countrys can't provide the enough energy for their people.With the help of nuclear power station,we can get enough energy to do what we like and enjoy everything that we need. It's also benefical to the country's economic development.
四、核能利弊英语作文
(nuclear energy) at present, energy can be obtained from various sources such as oil, coal, natural gas, solar energy, wind energy, etc., but conventional energy such as oil and coal are rapidly exhausted.
I think that due to technical reasons, solar heat can not be widely used immediately, and non clean energy will replace traditional energy, because people can freely control this energy and it is not polluted Dyeing, inexhaustible, is much safer than coal and oil.
Coal and oil combustion will also produce a lot of harmful gases, the air has been seriously polluted by these gases, threatening people's living environment and many accidents are due to the wrong use of this energy.
However, when we use nuclear energy, such things will not happen, although when the nuclear leakage, it will cause great harm to people's health and the environment, we can do enough to avoid these things, I believe that if we use nuclear energy in the right way, it will provide us with enough energy without any harm to us.
中文翻译:
(核能)现在,能源可以通过石油、煤炭、天然气、太阳能、风能等各种来源获得,但石油、煤炭等常规能源正迅速被消耗殆尽,我认为由于技术原因,太阳能热不能立即得到广泛应用,不清洁能源将取代传统能源,因为现在人们可以自由控制这种能源,而且不污染,取之不尽,比煤和石油安全得多。
煤和石油燃烧也会产生许多有害气体,空气已经被这些气体严重污染,威胁着人们的生活生活环境和许多事故都是由于错误地使用这种能源而发生的。
但是,当我们使用核能时,这种事情是不会发生的,尽管当核泄漏时,它会对人们的健康和环境造成极大的危害,我们可以做足够的工作来避免这些事情,我相信,如果我们以正确的方式使用核能,它将为我们提供足够的能源,而不会对我们造成任何伤害。
