Electrodialysis: Treatment of severe accident solution of VVER power plant

Popis výsledku v původním jazyce

To ensure the high level of nuclear safety is a crucial responsibility of NPP operators. Broadening the scope of readiness for all possible scenarios contributes to the improvement of nuclear safety. The background of presented project is readiness of NPP operators for non-project scenarios. However, the results of this work are applicable in the whole scope of liquid radioactive waste treatment. Besides the actual safety improvement, the high level of nuclear safety has also a positive impact on the public image of nuclear energy. This research arose form a project that is focused on the efficient treatment of large volume radioactive waste resulted from the (hypothetical) severe accident of NPP. In such case there will be created large volume (10 000 m3) of radioactive waste that would need to be cleaned. The presented work describes evaluation of usage of electrodialysis (ED) for a treatment of large volume of radioactive waste. Apart of the radioisotopes the post-accidental solution contains boric acid, potassium hydroxide and hydrazine. Due to the nature of present compounds the behaviour of such mixture is quite complex. The presented data shows behaviour of this solution during the separation via ED.
