Abstract

Abstract

The remediation and restoration of radioactive contaminated sites has become an important support to ensure the healthy and sustainable development of the nuclear industry. In this paper, according to the treatment requirements of radioactive contaminated soil in typical areas, the source term analysis and sorting principle test are carried out to determine the radioactive contaminated soil sorting and volume-reducing process scheme and the device design indicators. Then a novel radioactive contaminated soil sorting and volume-reducing device is designed, which could realize the functions of radioactive contaminated soil drying, screening, online detection and separation according to disposal requirements. The performance verification results show that the theoretical detection limit of ¹³⁷Cs in radioactive contaminated soil is 20.7 Bq/kg, and the treatment capacity can reach 106 kg/h, which meets the design indicator. The device is expected to realize the downgrade of part of the contaminated soil in a typical area from low-level radioactive waste to extremely low-level radioactive waste or extremely low-level radioactive waste to exempt waste in the follow-up project implementation. The research can provide theoretical guidance and experimental basis for the process design and engineering verification of radioactive contaminated soil treatment.
