英汉核电工程常用词汇英汉核电工程常用词汇核电工程是指利用核能发电的工程，其领域广泛，包括核反应堆、核燃料循环、辐射防护、核废物处理等多个方面。

在核电工程的过程中，涉及到许多专业技术的术语和词汇。

以下是一些英汉核电工程常用词汇及其解释。

1. Nuclear Power Plant（核电站）：一个核电站通常由一到多个核反应堆组成，可以按照发电容量分为小型、中型和大型核电站。

它还包括冷却系统、核燃料循环设备、电力传输系统等组成。

2. Nuclear Reactor（核反应堆）：一种通过核反应来产生能量的装置。

核反应堆分为热中子堆和快中子堆，用于发电的大多是热中子堆。

核反应堆通过核裂变反应来产生能量，并通过循环系统将热能转化为电能。

3. Nuclear Fuel（核燃料）：核反应堆中的燃料，一般采用铀或钚等放射性元素作为原料。

燃料通过核反应发生裂变反应产生热能，转化为电能。

4. Nuclear Radiation（核辐射）：指核反应放出的粒子或电磁辐射。

辐射分为电离辐射和非电离辐射，可对人体造成不良影响。

5. Nuclear Fission（核裂变）：指将原子核分裂成两个较小的核的过程。

核裂变是核反应堆发电的基本原理。

6. Nuclear Fusion（核聚变）：指将两个轻核聚合成较重核的过程。

核聚变是太阳等恒星的主要能量来源。

7. Radioactive Waste（放射性废物）：指在核燃料循环和核反应运行中产生的废料，其具有放射性，并且会对环境和人体造成影响。

8. Containment Building（容器建筑物）：指核反应堆的保护结构，用于防止核泄漏事故的发生。

容器建筑物通常由混凝土、钢筋等材料构成。

9. Coolant System（冷却系统）：指用于冷却核反应堆的系统，包括冷却剂、泵、换热器等组成，其功效在于将热能稳定地转移出去，保持核反应堆的正常运行。

10. Electrical Grid（电力网络）：指连接电站和用户的电力传输系统，包括输电线路、变电站、配电设施等组成。

Term 术语Definitions 定义解说Active equipment 有源设备Equipment which shall perform a mechanical motion as part of itssafety-related function.作为安全相关功能的一部分，进行机械运动的设备。

Aging 老化The effect of operation, environmental and system conditions onequipment during a period of time up to, but not including design basisevents, or the process of simulating these events.经过一段时间的使用，设备在环境整体影响下的变化，不包括设备本身基本设计方面的变化。

Component 组件Discrete items from which the equipment is assembled. 组装成设备的离散型零件。

Cutoff Frequency截止频率；切截频率The frequency in the response spectrum where the zero period acceleration asymptote begins. This is the frequency beyond which single degree of freedom oscillators exhibit no amplification of motion, and indicates the upper limit of the frequency content of the waveform being analyzed.频率响应谱中的零期渐近开始加速。

截止频率是单个自由振荡器在没有继续提速征兆情况下的频数，代表了受分析的波形曲线的上限频率。
