Reactor pressure vessel and internals 反应堆压力容器及内部构件

今天小编为大家带来一些压力容器内部构件的英文表述

The reactor pressure vessel and internals support and align the reactor core and its associated components.

反应堆压力容器和内部构件为反应堆堆芯及其相关部件提供支撑和对中。

The vessel and internals provide a flowpath to ensure adequate heat removal capability from the fuel assemblies.

反应堆容器和内部构件还提供流道，以确保具有足够的从燃料元件导出热量的能力

The reactor vessel is a cylindrical shellwith a welded hemispherical bottom head and a removable, flanged and gasketed,hemispherical upper head.

反应堆压力容器是立式圆筒形容器，底部有焊死的下封头，顶部有可拆卸的法兰连接的半球形上封头。

The vessel contains the core, core support structures, control rod, and other components associated with the core.

反应堆压力容器内装有堆芯、堆芯支承件、控制棒及其他与堆芯相关的部件

The head flange is sealed to the vesselflange by two metallic “O” rings which fit into grooves machined in bothflanges.

封头法兰和反应堆容器法兰之间靠两道金属O形环密封，O形环装在两个法兰上机加工的槽内。

The reactor vessel and heads are constructed of a manganese molybdenum nickel alloy steel with all surfaces incontact with the reactor coolant clad with weld-deposited stainless steel for corrosion resistance.

反应堆容器和封头都由锰钼镍合金钢制成，凡与反应堆冷却剂接触的表面都堆焊不锈钢，以抗腐蚀。

Reactor vessel closure head penetrations include control rod drive mechanism adapters and reactor vessel head vent,while the bottom head contains penetrations for connection and entry of thein-core nuclear instrumentation.

容器的上封头贯穿件有控制棒驱动机构管座和堆容器封头排气孔；而容器的下封头贯穿件有连接堆芯内核仪表的管座，可移动式核仪表可由此进入堆芯。

The reactor internals consist of the lower support structure, the upper support structure and the in-core instrumentation support structure.
