核电厂仪表及其供电设备安全分级是核电厂设备安全分级的一部分,既与核电厂安全密切相关,又直接影响核电厂的造价,是核电厂建造中必须解决的重要问题之一。 核工业标准化研究所1991年组织技术人员在参考了IEC/TC45/SC2《核电厂安全重要仪表和控制系统分级》和KCC-E等国际和国外先进标准后,结合我国国情编制了GB/T15474-95《核电厂仪表和控制系统及其供电设备安全分级》。
Nuclear power plant instrumentation and power supply equipment safety classification of nuclear power plant equipment safety classification is not only part of the safety of nuclear power plants are closely related, but also directly affect the cost of nuclear power plant construction is one of the important issues must be addressed in the construction of nuclear power plants. Institute of Nuclear Industry Standardization In 1991, after referring to the international and foreign advanced standards such as IEC / TC45 / SC2 “Nuclear Power Plant Safety Important Meters and Control System Classification” and KCC-E, the organization’s technical personnel compiled the GB / T15474- 95 “Nuclear power plant instrumentation and control systems and their power supply equipment safety rating.”
