安全壳

分享到:
  1. Containment is usually defined as that system whose functional responsibility is to prevent the release of radioactive fission products to the atmosphere.
 
  1.安全壳的主要功能就是为了防止放射性裂变产物释放到大气中去。
 
  2. The containment also provides biological shielding during not only normal operation but also the event of a loss of coolant accident.
 
  2.同时,在正常运行和失水事故时,安全壳提供生物屏蔽。
 
  3. The containment structure serves to house the reactor system equipment, provide foundations for that equipment, permit environment control for the equipment within it and provide a service area for maintenance.
 
  3.安全壳作为一个建筑物,用于容纳反应堆各系统的设备、为各设备创造合适环境和提供检修平台。
 
  4. A carbon steel liner is utilized to provide a leak proof vapor barrier for containment of concrete construction.
 
  4.为防止混凝土结构的安全壳泄露,其内部有碳钢的衬垫。
 
  5. There are three types of PWR containment: large dry containment, subatmospheric containment and ice condenser containment.
 
  5. PWR有3种形式的安全壳:大而干燥的安全壳,负压型的安全壳和冰凝式安全壳。
 
  6. The containment spray system functions to reduce the containment pressure and airborne fission products in the containment atmosphere following a steam line break or loss of coolant accident.
 
  6.安全壳喷淋系统的功能:在MSLB或LOCA时降低安全壳的压力和去除大气中的气载裂变产物。
 
  7. The containment spray system consists of two pumps, spray ring headers, a spray additive tank, a number of motor operated isolation valves and all necessary piping, instruments etc.
 
  7.安全壳喷淋系统内有两台喷淋泵,喷嘴,喷淋添加箱,许多安全壳隔离阀和相关的管道仪表等。
 
  8. Sodium hydroxide is added to the containment spray water to enhance absorption of the airborne fission product iodine and to retain the iodine in the containment sump solution.
 
  8.喷淋液中添加NaOH用于加强吸收气载放射性产物碘,并将碘保留在地坑的溶液中。
 
  9. The purpose of hydrogen recombiner is to remove hydrogen from the containment by combing hydrogen with oxygen to form water.
 
  9.氢气复合器用于去除安全壳中的氢气,其原理是将氢气和氧气结合生成水。
 
  10.  Containment isolation system provides the means of isolating systems that pass through containment penetrations so as to confine any radioactivity that may be released in the containment following an accident to the containment.
 
  10. 安全壳隔离系统主要是在事故工况下将通过安全壳的贯穿件隔离,防止放射性产物逸出。
 
  11. Containment penetrations are designed to ensure that containment leakage does exceed the limit of Technical Specifications.
 
  11. 安全壳贯穿件设计用于保证安全壳泄漏率低于技术规格书的限值。
 
  12. The common limits to the leakage of radioactivity after an accident are between one tenth and four tenths of one percent of containment volume per day and the actual leakage should be verified experimentally prior to operation and periodically there after.
 
  12. 事故中对于放射性泄露的限制一般为每天,每百分之一安全壳体积的1/10到4/10(也就是1/1000~4/1000)。另外在运行前需做安全壳泄露率试验,并在之后周期性地执行。
