An earlier reactor was the Zimmer Power plant in Cincinnati, which was originally designed as a nuclear plant but it was converted to natural gas before it began operating.

更早一些的例子是，位于辛辛那提的奇摩尔发电厂，最初的设计是核电厂，但是在运行之前改为燃气发电。

Next is the cost of as much as $10 billion and five years to build each reactor, compared with about $1 billion for a natural gas-fired power plant.

即使突破了前面的重重难关，开发商还要花费将近百亿美金和五年的时间建造每一个反应堆。 相较之下，一个燃气发电厂的造价不过十亿而已。

Large temperature and concentration differences taking place in CVD process lead to natural convection and concentration diffusion which interact with forced convection and complex reactor geometries.

在CVD过程中，存在着大的温度差和浓度差，将引发自然对流和浓度扩散，它们又与气体的强迫流动以及反应器的几何尺寸和形状相互影响。

Never before has a single operator faced the possibility of multiple reactor meltdowns following after a natural disaster that has made it tough to get emergency equipment even such basics as lights to a plant site.

Iran also began building an actual weapons reactor, a 40 MW heavy water reactor at Arak, that would take natural uranium, and produce plutonium.
