11、B: Well, in my opinion,nuclear energyis our best hope for the future.(唔,在我看来,核能是我们将来最大的希望所在。) 12、nuclear energymay overtake oil as the main fuel.(核能可能会超过石油成为主要燃料。) 13、nuclear energyis produced by atomic fission.(原子裂变产生了核能。) 14、Around ...
Nuclear energy comes from mass-to-energy conversions. Nuclear energy is produced by a controlled nuclear chain reaction and creates heat—which is used to boil water, produce steam, and drive a steam turbine. Nuclear power can come from the fission of uranium, plutonium or thorium or the fusio...

Nuclear energy relies on deposit of fuel material which is a finite, albeit very large, resource Basics Of Nuclear Energy Nuclear energy is produced through the process ofnuclear fission, in which the nucleus of an atom is split into smaller nuclei, releasing a large amount of energy in the ...
How is nuclear energy produced? In general, nuclear energy is produced or consumed innuclear reactions. The most common nuclear reactions are nuclear fission, nuclear fusion, and nuclear decay. But there are much moretypes of nuclear reactions. ...
1 One of the major problems of nuclear energy is the inability of scientists to discover a safe way to dispose of the radioactive wastes which occur throughout the nuclear process. Many of these wastes remain dangerously active for tens of thousands of years, while others have a life span ...
Not everyone is delighted with the idea of marine nuclear power. Rashid Alimov, head of energy projects at Greenpeace Russia, an environmental charity, argues that offshore plants could be boarded by pirates or terrorists, be struck by an iceberg or might evade safety rules that are hard to ...
A. is very cheap B. produces a lot of electricity with little fuel C. is completely safe D. does not need any maintenance 相关知识点: 试题来源: 解析 B。中文解析:文章中提到核能的一个优点是它可以用相对较少的燃料产生大量的电力,所以答案是 B。A 选项文中未提及价格便宜;C 选项错误,因为文中...
