1、The technology under construction here, known as a pebble-bed reactor, is not new.───这种名为球床核反应堆的技术并不是新近才出现的。
2、they have an operating pebble bed reactor now, they have a small research reactor and it's being proposed in South Africa.───他们现在正在运作一个卵石层反应堆，他们有一个小的研究反应堆，在南非也得到了提议。
3、Another type of high temperature gas reactor is what we call a pebble bed reactor.───另一种高温的气体反应堆是，我们称之为卵石层反应堆。
4、The way these pebble bed reactors work is the helium comes in up the side and down through the pebble bed. It's not a fluidised bed.───这些卵石层反应堆运作的方式是，氦从这面的上面进来，然后，通过这个卵石层再出去，这不是液化层。
5、Pebble bed reactors are small , which suits remote and rural areas and makes them easy to expand .───球床反应堆体积小，适于建在偏远农村地区，而且易于扩展。
6、It has also continued to develop a novel "pebble bed" nuclear reactor that is smaller and probably safer than conventional reactors.───它还在继续开发一种新型的“球床”核反应堆，这种反应堆规模更小，比传统的反应堆更加安全。
7、Each "pebble" in a pebble-bed gas reactor is a graphite fuel sphere the size of a tennis ball.───在一个球形气体反应堆里的每一个“小球”都是一个网球大小的石墨燃料球。
8、A demonstration plant of a completely different type, a "pebble bed" reactor, is scheduled to be built in SouthAfrica starting in 2009.───一座演示用的电站却是另一种类型，“卵形床”反应堆，计划在2009年南非开始建造。
9、And this is done because the control rods are not in the pebble bed.───这已经完成了，因为控制棒，不在卵石层那。
1、In order to ensure the high availability of pebble bed type high temperature gas cooling reactor, it is the critical process to measure the burn-up level for each ball in accurate and efficient way.
2、The paper describes the building-up process of a large size rotary jet slip-casting pile by quick pore-forming in bulky iron slag layer and in river banks floated pebble bed.
3、Now the pebble bed reactor has the same basic safety features as a high temperature prismatic reactor in a sense that it has a meltdown free core.
