The results of an experimental investigation of the changes occurring in the properties of heat-exchanger material and the thermal conductivity as a result of non-soluble aerosol deposition on heat-exchange surfaces of the passive system removing heat from the containment during severe accidents at NPP are reported. As the investigations showed, the deposited aerosol does not significantly influence the heat exchange between the steam-gas mixture and the cooling water flowing through the heat exchanger.

核电厂发生严重事故期间气溶胶沉积引起换热器材料特性变化的研究

对核电厂严重事故期间从安全壳带走热量的被动系统热交换表面上不溶性气溶胶沉积导致换热器材料特性和热导率变化的实验研究结果被报道。研究表明,沉积的气溶胶不会显着影响蒸汽-气体混合物与流经换热器的冷却水之间的热交换。
