Abstract:

In order to satisfy the new Chinese standard of effluent water drained from nuclear power plant, the improvement principle of radioactive waste liquid processing system in AP1000 inland nuclear power plant was determined, based on the analysis of the sources and characteristics of radioactive waste liquid produced by AP1000 reactor. Several improving measures such as adopting chemical flocculation, adding ion exchange beds and using macroporous ion exchange resins were developed based on the advantages and disadvantages comparison of several process programs. Demonstration tests were carried out and the results showed that the improved process could meet with the requirement of radioactive waste liquid processing system in inland AP1000 nuclear power plant.

Key words: AP1000, inland nuclear power plant, radioactive waste liquid processing system, chemical flocculation
