The government has said Japan is safe except for the immediate vicinity of the crippled plant, where work crews are still trying to bring the facility to a cold shutdown. 日本政府表示,除废弃核电站的紧邻地段外,日本其他地方都是安全的。目前核电站内仍然有工作人员在紧张工作,希望可以实现核电设备的冷停堆状态。
Local "emergency" stop switches shall be provided for safe shutdown. 应提供本地“应急”停车开关,用于安全关闭。
Emergency interlock shut-off system and overpressure vent system are set on the raw gas pipeline to the unit, so in case of abnormality, safe emergency shutdown can be realized timely. 在进单元的原料气管线上设置了紧急联锁切断及超压放空系统,确保出现异常情况时能及时实现安全紧急停车。
TEPCO insists it can still achieve a safe "cold shutdown" by January, but has been forced to make changes to its strategy for cooling the reactors. 东电坚称仍能在明年1月前安全实现“冷停堆”,但已被迫调整了冷却反应堆的策略。
And a successful example proves that the technique of online leak sealing has a prominent function in ensuring the long period safe operation and eliminating unexpected shutdown of power supply plant. 并通过成功的应用实例,论证了带压密封技术在确保电力系统安全长周期运行,避免非计划停产方面的突出效能。
The Determination of Safe Shutdown Time for Waxy Crude Oil Pipeline 含蜡原油管道安全停输时间的确定
For petrochemical plant in cold area in winter, to make sure of safe and stable operation and start-up or shutdown in emergency, antifreezing measures of equipment and pipeline and base frost heave prevention methods must be considered thoroughly. 在冬季严寒地区,为保证石化装置能安全稳定生产并能在紧急情况下开停车,要周密考虑设备管线的防冻措施及防地基冻胀。
Thus the operation safety is ensured and sensitivity increased; added UPS as backup power supply ensures safe shutdown and the indication of the reactor power at reactor shutdown. 增设UPS不间断电源作系统安全电源,保证可靠停堆与在反应堆失去全部电源情况下指示堆功率。
Such method provides the basis of calculation for determining the safe shutdown period of pipeline in different seasons in a more reasonable way. 该方法为更合理地确定管道在不同季节的安全传输时间提供了计算依据。
Control Parameters of Safe Shutdown Time for Nuclear Power Plants under Strong Earthquake 强震作用下核电站安全停堆时间的控制参数
The process of temperature decrease is the key to determine the safe time of shutdown in the whole pipeline due to overhead pipeline without soil thermal storage to slow up heat dissipation. 由于架空原油管道没有土壤的蓄热来减缓管内原油的热散失,架空原油管道的温降过程往往成为决定整条管道允许停输时间的关键。
The auxiliary power supply of Nuclear Power Station is used to supply the engineered safety features to ensure the safe shutdown of the reactor, when unit trip causes the house supply switch from Main Transformer to it. 核电站的辅助电源系统作为安全电源,在机组故障导致厂用电从主电网切换到辅助电源时向必须运行的专设安全设施供电,以保证反应堆安全停堆。
