Ventilation scheme analysis and optimization of a disposal cavern for low and intermediate level radioactive waste
摘要：
介绍了某低中放废物处置洞室的通风方案设计，利用CFD数值模拟分析方法对通风方案设计中的自然通风工况进行了分析论证，结果表明：自然通风工况合理有效，能够满足处置洞室一定时期内的环境要求。提出利用工程地常年稳定的自然风条件优化排风竖井设置的方法，结合CFD模拟分析结果确定排风竖井的具体优化措施。
Abstract：
Presents a ventilation scheme design of a disposal cavern for low and intermediate level radioactive waste. Using CFD numerical simulation method, analyses and verifies the natural ventilation condition. The results show that the natural ventilation condition is reasonable and effective, and can meet the environmental requirements for the disposal cavern within a certain period of time. Proposes a method to optimize the setting of ventilation shafts using perennial natural wind in the project location, and determines the specific optimization measures in view of the CFD numerical simulation result.
