In the process of nuclear energy utilization, an issue that cannot be ignored is the management and disposal of radioactive wastewater. During the construction and operation of nuclear energy facilities, there are two main types of radioactive liquid waste – nuclear sewage and nuclear wastewater. Although the two may be used in general terms in some cases, they differ in their professional definition in terms of the context in which they are generated, the intensity of the radioactivity, and the way in which they are processed. The following is an introduction and comparison of the concepts and differences between nuclear sewage and nuclear wastewater. Nuclear sewage: Nuclear sewage is mainly used in wastewater containing radioactive materials generated during the operation of nuclear energy facilities or in the event of an accident. For example, in the day-to-day operation of a nuclear power plant, there may be various links such as cooling systems, equipment cleaning, leak emergency response, etc. Especially in serious nuclear accidents, due to direct contact with nuclear fuel, the content of radioactive elements in these sewage is extremely high, including but not limited to uranium, plutonium, cesium, strontium, iodine, cobalt, etc., which poses a great potential risk to the ecological environment and human health.
Nuclear wastewater: Nuclear wastewater refers specifically to wastewater generated during the normal operating life of a nuclear power plant, especially during the cooling of the reactor and after the treatment of radioactive waste. Nuclear wastewater also contains radioactive materials, but its radioactivity level is relatively low compared to nuclear wastewater, which is usually treated with some purification. However, it is important to note that even after treatment, nuclear wastewater may still contain radioactive isotopes that are difficult to remove completely, such as tritium, so even if its radioactivity levels have been significantly reduced, external discharge will still need to comply with strict regulations and standards.
Summary
To sum up, although nuclear wastewater and nuclear wastewater are both radioactive wastewater produced in the process of nuclear energy utilization, there are obvious differences between them. Nuclear sewage is mostly related to accidents or abnormal operations, and its radioactivity intensity is high, and it is difficult to treat. Nuclear wastewater, on the other hand, is mainly due to the routine operation of nuclear power plants, and has a low level of radioactivity after treatment, but may contain persistent radioactive materials. The management and disposal of these two types of wastewater requires a rigorous scientific attitude and a high sense of responsibility to ensure that the potential impact on the environment and public health is minimized.
