Abstract

To optimize the operational parameters of the 2 000-ton super compactor in the solid waste compaction and packaging system of the nuclear power plant, the work aims to select five typical categories of solid wastes from nuclear power plants, including plastics, rubber, paper, thin-walled metals, and textiles to systematically investigate the effects of key process parameters such as compaction force and holding time on the super compactor. Furthermore, the rebound behavior of pellets derived from different technical waste types is measured and statistically evaluated over extended storage periods. Experimental results demonstrated that the contribution of compaction force to volume reduction efficiency diminished with the increasing force magnitude. The holding time exhibited no significant impact on super compactor outcomes and the rebound of pellets did not increase substantially over time. Based on experimental laws, an optimized process parameter scheme featuring stepped pressurization and shortened pressure holding time is proposed. This scheme can reduce equipment energy consumption and component wear while maintaining unchanged volume reduction indicators, and provides measured data support for process tuning of the nuclear solid waste compaction line.
