Study on Core Power Capability during Stretch-Out for Ling'ao Nuclear Power Station

Daya Bay Nuclear Power Operation and Management Co. Ltd., Shenzhen, Guangdong, 518124, China

摘要: 本文主要分析了岭澳核电站延伸运行工况下的功率能力。利用中子学计算程序对岭澳核电站延伸运行I类工况和II类工况下可能的堆芯功率分布进行了模拟,论证了I、II类工况下反映堆芯安全性的线功率密度裕度和偏离泡核沸腾比(DNBR)裕度。与自然循环相比,延伸运行工况下的功率能力具有更大的裕度。

Abstract: The core power capability during the stretch out for Ling’ao nuclear power station is studied margins increase during the stretch out compared with that in natural cycle.in this paper.The possible power distributions during the stretch out in condition I and condition II are simulated with several neutronic codes.The linear power density and DNBR margins in condition I and condition II,which reflects the core safety,have been justified.It also verified that the core power capability
