气溶胶迁移机理试验是大型先进压水堆重大专项课题“严重事故下放射源项及迁移机理研究”的重要研究内容之一,利用建立的气溶胶迁移机理试验平台,开展试验研究,探索严重事故状态下非能动安全壳冷却系统对裂变产物迁移的影响机理,为AP系列严重事故的预防和缓解措施研究提供技术基础。根据AP系列核电厂非能动安全壳冷却系统特点,并参考国外同类试验,设计并建造了气溶胶迁
Aerosol migration mechanism test is one of the major research topics of large-scale advanced pressurized water reactor major project “research on radioactive items under severe accident and migration mechanism”, using the established experimental platform of aerosol migration mechanism to carry out experimental research and exploration The mechanism of influence of the passive containment cooling system on the migration of fission products under severe accident conditions provides the technical basis for the research on the prevention and mitigation measures of AP series serious accidents. According to the AP series nuclear power plant passive containment cooling system characteristics, and reference to similar experiments abroad, the design and construction of aerosol migration
