岭澳二期防火分区的优化和改进

针对岭澳二期核电厂防火设计特点,并结合近年来在防火设计工作中的经验,对岭澳二期防火分区提出了优化方案。论文首先对岭澳二期目前的防火分区划分情况进行了介绍,然后通过具体示例分析,提出了进一步优化或改进的措施。这些优化包含防火分区类型划分、防火分区边界的优化等。这些优化在确保核电厂防火设计安全性的前提下提高了经济性。该防火分区优化和改进的方法对后续核电厂防火改进及新研发核电堆型的防火分区设计有重要指导意义。

The Optimization and Upgrade of Fire Zone Partitioning in Lingao Phase ⅡNPP

This study provided some optimized fire zone partitioning concepts for Lingao Phase 17 nuclear power plant. These upgrades were based on the plant design characteristics and the recent technology development in fire zone partitioning. It first gave a brief introduction about the current fire zone applied in Ling ao Phase II. Through some specific cases, the optimized or upgraded concept was proposed. These included the proper partition ways for different fire zones, fire zone boundary optimization, etc. All these up grades improved the plant economy while assured the plant fire safety design. These fire partitioning optimization and upgrade concept can be an important guidance used in the other nuclear power plants fire protection upgrade and the fire partitioning design of the newreactor type.
