天然蒸发池技术处理低水平放射性废液的发展概况

天然蒸发池技术是利用太阳能对放射性废液中多余水分蒸发、去除的一种处理方法。由于其对运行设施要求简单，不需要过多的日常维护，并具有对低放射性废液净化系数较高、处理量大、节能等特点，因此天然蒸发池技术成为一种较为常用的低放射性废液处理方法。然而，天然蒸发池的运行设施占地面积较大，需要日照时间较长，该方法的应用受到一定限制。本文通过国内外具体实例和经验，介绍了天然蒸发池技术的改进及应用情况。

Research and Development of Solar Evaporation on Low Level Radioactive Liquid Waste

Solar evaporation, which can save energy and obtain the higher decontamination factor, the larger treatment capability with the simpler designed and easy operation, was one of the general methods to treat low level radioactive liquid waste. However, the use of solar evaporation was limited because the facilities had to occupy the larger area and require sunshine for the longer duration, etc. Several cases form USA, Australian, India and South Korea were presented on R&D of solar evaporation to treat low level radioactive liquid waste.
