查询词典 reactor core

Seismic analysis is one of most important parts of fast breeder reactor core design. It is necessary for structural integrity assessment and analysis of variation of reactivity under the earthquake. Moreover some important data for qualification of the scram capability of the control rods during the earthquake could be provided.

快堆堆芯抗震分析是堆芯设计的重要组成部分，它将为堆芯在地震作用下的结构完整性评价和堆芯反应性变化分析提供必要的数据，同时为控制棒的可插入性评价提供参考。

Fuel assemblies of fast breeder reactor core submerged in the liquid sodium may vibrate under the earthquake, which possibly leads to structural damage of fuel assembly or structural deformation of the core and affects structural integrity and safety qualification of the core.

浸没在液态钠中的快堆堆芯组件在地震作用下发生振动，可能导致组件结构损坏或堆芯结构变形，从而影响反应堆结构完整性和安全。

At this time, which one of the following will cause the fission rate in the reactor core

The analytic results obtained from the PCT evaluations revealed that the most limiting accident was the case with a break at the Main Steamline Outside Containment. Its PCT was 1289.15 ℉, which is much below the upper temperature limit of 2200℉ set by the nuclear regulatory authority. The most limiting accident for the minimum water level measured outside the core shroud is the case with a break at the High Pressure Core Flooder Line, the minimum water level drops to 18.4 ft. For this case, even though the water level has dropped to 11.6 ft below the top of the active fuel, the reactor core was still completely covered by the two-phase water.

分析结果显示，对燃料护套最高温度而言，最严重之事故为围阻体外主蒸汽管路破口，其燃料护套最高温度为1289.15 ℉，此温度远在法规10CFR50.46所定之限值 2200 ℉以下；对反应炉最低水位而言，则最严重之事故为高压注水系统管路破口，反应炉降水区最低水位降至18.4 ft，约在有效燃料顶部以下11.6 ft，然而炉心内部仍为双相饱和流体所完全覆盖。

Natural circulation is adopted in the flowage of reactor core.

其堆芯流动采用自然循环。

In this paper, the thermal-hydraulic behaviors in the reactor core in hospital neutron irradiator is investigated .

本文对医院中子照射器的反应堆堆芯结构进行了热工水力计算分析。

How to cool down the reactor core after it is shutdown is one of the most important safety problems for China Advanced Research Reactor.

停堆后冷却问题是中国先进研究堆重要的安全问题之一。

The hot gas duct of China 500 MW Pilot High-Temperature Gas-cooled Reactor connects the reactor pressure vessel and the steam generator. The hot gas duct is the main passage of the helium from the reactor core to the steam generator.

500 MW高温气冷堆示范电站的反应堆压力容器与蒸汽发生器通过热气导管连接，热气导管是反应堆堆芯出口氦气导入蒸汽发生器的主要通道。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
