U, Cs, Ba, Rb, K, and Ca isotopic ratios were determined on three CsMPs (3.79\u2013780\u2009Bq) collected within ~10\u2009km from the FDNPP to determine the CsMPs\u2019 origin and mechanism of formation. Apart from crystalline Fe-pollucite, CsFeSi2O6\u2009\u00b7\u2009nH2O, CsMPs are comprised mainly of Zn\u2013Fe-oxide nanoparticles in a SiO2 glass matrix (up to ~30 wt% of Cs and ~1\u2009wt% of U mainly associated with Zn\u2013Fe-oxide). The 235U/238U values in two CsMPs: 0.030 (\u00b10.005) and 0.029 (\u00b10.003), are consistent with that of enriched nuclear fuel. The values are higher than the average burnup estimated by the ORIGEN code and lower than non-irradiated fuel, suggesting non-uniform volatilization of U from melted fuels with different levels of burnup, followed by sorption onto Zn\u2013Fe-oxides. The nano-scale texture and isotopic analyses provide a partial record of the chemical reactions that occurred in the fuel during meltdown. Also, the CsMPs were an important medium of transport for the released radionuclides in a respirable form.", "subitem_description_type": "Abstract"}]}, "item_5_publisher_27": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "Nature Publishing Group"}]}, "item_5_relation_10": {"attribute_name": "PubMed\u756a\u53f7", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "28710475", "subitem_relation_type_select": "PMID"}}]}, "item_5_relation_11": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1038/s41598-017-05910-z", "subitem_relation_type_select": "DOI"}}]}, "item_5_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "\u00a9 The Author(s) 2017"}, {"subitem_rights": "This article is licensed under a Creative Commons Attribution 4.0 International License, which permits use, sharing, adaptation, distribution and reproduction in any medium or format, as long as you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made.
