在确保安全的基础上高效发展核电,是当前我国核能建设的一项重要政策。然而纵观国内各核电厂核岛主设备到货均滞后严重,导致主设备到货后主回路工期十分紧张,资源配置和投入以及施工逻辑都需有效地优化。本文结合本人近十年核电工作经验简明论述核岛主回路施工资源、工期优化思路和办法。 Efficient nuclear power development on the basis of ensuring safety is an important policy for China’s nuclear energy construction at present. However, taking a general view of the serious lag in the arrival of the main equipment of nuclear power plants in various nuclear power plants in China, the construction of the main circuit after the arrival of the main equipment is very tense and the allocation and input of resources as well as the construction logic need to be effectively optimized. Based on my own experience in nuclear power in recent ten years, this paper briefly discusses the construction resources and construction period of main nuclear circuit.
