我心中的核电作文
【篇一：核电的利与弊】
核电的利与弊
众所周知，核电对于当代的技术发展有着很大的帮助，那么这帮助是怎样的？它就没有什么弊端吗？让我们一起来了解一下吧！
随着国民经济的发展，全社会对电力的需求不断增长。据中电联统计，2011年全社会用电量4.69万亿千瓦时，总装机10.56亿千瓦。据其预测，至2017年，全国社会用电量将达5.99--6.57万亿千瓦时。电力需求的迅速增长将有利于促进对电力行业的发展。
发展核电对满足经济和社会发张不断增长的能源需求，保障能源供应与安全，保护环境，实现电力结构优化和可持续发展，提升我国综合经济实力和工业技术水平具有重要意义。
促进社会发展，这当然是离不开核电的，但和点它能“利在‘千秋’”吗？
1986年4月25日，前苏联切尔诺贝利核电站的4号动力站开始按计划进行定期维修。然而由于连续的操作失误，4号站反应堆状态十分不稳定。1986年4月36日对于切尔诺贝利核电站来说是悲剧开始的日子。凌晨1点23分两声沉闷的爆炸声在这寂静的早上显得尤为突出。随着爆炸声，一条30多米高的犹如一条打火龙似的火柱掀开了反应堆的外壳，冲向天空，高达2000℃的烈焰吞噬着机房，熔化了粗大的钢架。携带着高放射性物质和水蒸气，和着尘埃随着浓烟升腾、弥#x6f2b;、遮天蔽日。而消防人员只能靠着直升机从空中向下投放含铅和硼的沙袋，以封往反应堆，阻止放射性物质的外泄。在这场事故中当场死亡2人，至1992年，已有7000多人死于这次的核污染。可见喝点再给人带来利润的同时存在的祸患。
“利在当代，弊在千秋”，我们在核电促进发展的同时也要警惕它所存在的祸端。

a string of accidents, including the partial collapseof a cooling tower in 2007 and the discovery of anunderground pipe system leakage, raised seriousquestions about both vermont yankee’s safety andentergy’s management-especially after the companymade misleading statements about the pipe.
译文：
一系列的事故，包括2007年冷却塔的部分倒塌，以及一个地下管道系统被发现泄漏，都使得人们严重质疑佛蒙特州扬基核电站的安全性和安特吉公司的管理——尤其是在该公司对其管道问题作出欺骗性的声明之后。
点睛：
本句的主干是a string of accidents raised serious questions。including?部分作插入语，补充说明accidents;破折号起强调作用，其后是由after引导的时间状语从句。
a string of意为“一系列”，collapse of a cooling tower意为“冷却塔昀倒塌”，underground pipe system leakage意为“地下管道系统泄漏”，raise serious questions about.?意为“对?提出严重质疑”, make misleadingstatements about...意为“对?作出欺骗性声明”。

【篇三：支持核能(英语作文)】
i support nuclear energy
today, energy crisis is so serious that scientist are finding many new energy technologies, such as wind power and nuclear energy. although they all have their own advantages and disadvantages, i support nuclear energy because of the following four reasons.
first, nuclear energy is more reliable than wind power. wind turbines need enough wind to produce electricity, which is unstable, however, nuclear energy doesnt have to consider the influence of the weather or other factors. it can generate reliable electricity for a long time. so there is no doubt that the market is more welcome of nuclear energy, what more, the capacity factor of nuclear energy is much higher than wind power, which measures the reliability or dependability of an energy source. according to information from the awea, nuclear energy plants are nearly three times as reliable as wind power.
second, scale is another area where nuclear ene
rgy trumps wind power. the latest nuclear reactor designs can produce up to 1500 megawatts, as compared with the largest wind turbine , which generates a mere 5 megawatts. in other words, if output reliability is taken into account, approximately 863 wind turbines are required to equal the output of one nuclear power plant, what an amazing disparity!
third, nuclear energy is also a better way to eliminate pollution/co2 emissions.although wind power is low carbon too, its technologies fail to deliver both low cost and reliability. nuclear energy can provide a reliably large quantity of pollution-free, low-cost energy, which is impossible for wind power.
last bust not least,nuclear energy can be commercialized but wind power cant. nuclear energy plants can be built in large numbers to meet the desired electric generation needs of an entire nation. by contrast, wind power suffers from intermittency problems, limited natural resource awailability, and power grid distribution issues.
from what has been discussed above, nuclear energy is better than wind power.
