Economic-energy-exergy-risk (3ER) assessment of novel integrated ammonia synthesis process and modified sulfur-iodine cycle for co-production of ammonia and sulfuric acid

A novel integrated modified sulfur cycle and ammonia production process was suggested for the co-generation of sulfuric acid. Exergy analysis, heat integration, and safety assessment were conducted to investigate the feasibility and analyze the process. The exergy analysis showed that the highest exergy destruction occurred in the section with the most considerable temperature difference involved with a large flow rate. The heat integration - an economic assessment, confirmed that the total cost was estimated to be reduced by 10.9% at the minimum temperature difference of 39 oC. The failure rate contribution to the overall system was 19%, 11%, 22%, and 47% from the Bunsen section, H2SO4 concentration section, HI decomposition section, ammonia production section explosion, fire, and structural damage contributed 82%, 16%, and 2% to the overall system in terms of accident scenario. The accident cost contributed 84% and 16% of accident injury costs to the overall system, respectively. For the sectional based contribution, section 1 (Bunsen process), SA concentration, section 3, and ammonia production process contributed 45%, 29%, 19%, and 6% to the accident injury cost in the overall system, respectively. As a result of individual section failure to the whole section, failure in Bunsen process and HI decomposition led to failure in production of all the products. Failure in NH3 production section led to production in concentrated H2SO4 and H2. The failure in H2SO4 section leads to production in NH3 and diluted H2SO4 concentration. The failure in H2SO4 concentration, NH3 production, and Bunsen process and HI decomposition contributed to the higher failure rate in ascending order.11Nsciescopuskc

Safety Assessment for the Landfill Disposal of Decommissioning Waste Solidified by Magnesium Potassium Phosphate Cement

The decommissioning of a nuclear power plant generates large amounts of radioactive waste, which is of several types. Radioactive concrete powder is classified as low-level waste, which can be disposed of in a landfill. However, its safe disposal in a landfill requires that it be immobilized by solidification using cement. Herein, a safety assessment on the disposal of solidified radioactive concrete powder waste in a conceptual landfill site is performed using RESRAD. Furthermore, sensitivity analyses of certain selected input parameters are conducted to investigate their impact on exposure doses. The exposure doses are estimated, and the relative impact of each pathway on them during the disposal of this waste is assessed. The results of this study can be used to obtain information for designing a landfill site for the safe disposal of low-level radioactive waste generated from the decommissioning of a nuclear power plant.11Nscopuskc
