百万千瓦级核电厂放射性废油的处理方法
摘要：
本发明提供一种百万千瓦级核电厂放射性废油的处理方法。该处理方法包括以下步骤：检测放射性废油的放射性活度浓度，若放射性活度浓度≤0.1Bq/g，作为解控油，若放射性活度浓度＞0.1Bq/g，则进行催化处理、过滤、离子交换处理等，获得解控油；对解控油依次进行酸氧化处理、碱洗处理，获得中性油液，并用于燃烧供热。本处理方法对放射性废油进行催化和过滤处理，并采用离子交换方式使得放射性废油中离子级的放射性核素被去除，从而获得达到排放标准的解控油，随后将解控油用于燃烧供热，一方面避免了直接对放射性废油燃烧产生的放射性残渣污染物，另一方面解决了核电厂放射性废油堆积的问题，第三方面，还能够实现废物的资源化利用。
摘要（英）：

The invention provides a processing method for radioactive waste oil in a million-kilowatt-class nuclear power plant. The processing method comprises the following steps: a radioactivity concentrationof the radioactive waste oil is detected, when the radioactivity concentration is <= 0.1 Bq/g, the radioactive waste oil is used as uncontrolled oil, and when the radioactivity concentration is > 0.1Bq/g, catalytic treatment is performed, filtration is performed, and ion exchange treatment is performed to obtain uncontrolled oil; and the uncontrolled oil is subjected to acid oxidation treatment,alkali washing treatment is performed to obtain neutral oil, and the neutral oil is used for combustion and heat supply. The processing method provided by the invention catalyzes and filters the radioactive waste oil, and adopts an ion exchange method to remove ion-level radionuclide in the radioactive waste oil, thereby obtaining the uncontrolled oil reaching a discharge standard; and the uncontrolled oil is used for the combustion and the heat supply, so that radioactive residue pollutants generated by direct burning of the radioactive waste oil are avoided, the problem of accumulation of the radioactive waste oil in the nuclear power plant is solved, and resource utilization of waste can be realized.
