摘要
为证明核电厂仪控设备按要求执行其功能时具有较高的可信度,需通过各项鉴定试验予以验证,而电磁兼容中辐射抗扰度试验(RS)就是很重要的验证项目,倍受核安全局、环境保护部华北核与辐射安全监督站等业界监管机构的广泛关注。在以往核电厂仪控设备的研制过程中,由于研发人员对电磁兼容性设计缺乏深入的认识,考虑不够充分,导致仪控设备在鉴定试验中出现各种问题,影响了鉴定和取证进度。本文基于中国核动力研究设计院研发的核电厂安全级DCS平台(NASPIC),针对电磁兼容性试验中风险系数较高、难度较大的辐射抗扰度试验提出了一系列优化设计方案。实践证明,这些设计方法极大地提升了核安全级仪控设备辐射抗扰度的能力,有效地帮助仪控设备顺利通过试验。
In order to verify a high degree of credibility when the I＆C equipment executing the required function in nuclear power plant, it is necessary to conduct a series of electromagnetic compatibility tests, which including the important radiation immunity test（RS）, a test that attracted a wide spread attention from some nuclear industry supervision institutes such as NNSA and NRO-NNSA. In the past nuclear power plant instrumentation and control equipment quality identification process, due to the lack of the basic understanding of the electromagnetic compatibility test, most people gave little consideration to electromagnetic compatibility during the development phase. As a result, big problems happened in the quality identification, which seriously affected the overall reliability of the equipment requirements and the quality identification progress. Based on the safety DCS platform（NASPIC） of nuclear power plant developed by Nuclear Power Institute of China （NPIC）, a series of design methods are proposed in this article, aiming at the radiation immunity test which is high-risk and difficult in the electromagnetic compatibility test. Practice has proved that, these design methods greatly enhance the radiation immunity ability of the nuclear safety classified I＆C equipments, effectively helped the I＆C equipments pass the test.
