CPR1000机组大修B10调整优化方案研究
Study on B10 Adjustment and Optimization Scheme of CPR1000 Unit Overhaul

该总结描述了一种用于CPR1000机组一回路提高B10丰度的系统及方法，系统包括：一回路系统、与一回路系统连接的硼溶液贮存箱，以及用于制备富集硼酸的临时装置；与临时装置连接的硼回收系统中间箱。该优化方案方法，通过临时装置将富集硼注入中间箱内，并利用中间箱、硼溶液贮存箱和换料水箱之间的硼水传输过程，将富集硼带入至相关系统，从而将一回路B10丰度提高至正常水平。
This paper presents a system and method designed to enhance the abundance of B10in the primary circuit of CPR1000 unit. The system comprises a primary circuit system, a boron solution storage tank connected to the primary circuit system, and a temporary device for preparing and enriching boric acid. An intermediate box of boron recovery system is connected to the temporary unit. In this optimization scheme, enriched boron is injected into the intermediate tank through a temporary device, and the transfer process of boron water between the intermediate tank, the boron solution storage tank, and the refueling tank are utilized to introduce enriched boron into the relevant system, thereby increasing the primary B10 abundance to normal levels.
