The surrogate debris was prepared from mixed oxide materials containing Gd2O3, with varying Gd concentrations. The emission spectra of the surrogate debris show that the optical emission lines at 501.5 nm and 510.3 nm are suitable for Gd detection in the nuclear fuel debris. LIBS measurements were further performed under gamma irradiation (0–10 kGy/h), resulting in a decrease in spectral intensities due to radiation-induced damage to the optical fiber. For quantification of Gd, robust calibration curves against gamma irradiation were established from the intensity ratio of Gd (501.5 nm)/Ce (474.5 nm) emission lines, yielding the limits of detection for Gd in the range of 0.03–0.08 wt%. These results demonstrate that FO-LIBS is a potential tool for in situ and remote analysis of nuclear fuel debris.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"MDPI"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.3390/app10248985","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.mdpi.com/2076-3417/10/24/8985/htm","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2076-3417","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Nakanishi, Ryuzo"}],"nameIdentifiers":[{"nameIdentifier":"1016309","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Saeki, Morihisa"}],"nameIdentifiers":[{"nameIdentifier":"1016310","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ikuo, Wakaida"}],"nameIdentifiers":[{"nameIdentifier":"1016311","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Oba, Hironori"}],"nameIdentifiers":[{"nameIdentifier":"1016312","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ryuzo, Nakanishi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1016313","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Morihisa, Saeki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1016314","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hironori, Oba","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1016315","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":" Detection of Gadolinium in Surrogate Nuclear Fuel Debris Using  Fiber-Optic Laser-Induced Breakdown Spectroscopy under Gamma Irradiation","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":" Detection of Gadolinium in Surrogate Nuclear Fuel Debris Using  Fiber-Optic Laser-Induced Breakdown Spectroscopy under Gamma Irradiation"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-12-14"},"publish_date":"2020-12-14","publish_status":"0","recid":"81342","relation_version_is_last":true,"title":[" Detection of Gadolinium in Surrogate Nuclear Fuel Debris Using  Fiber-Optic Laser-Induced Breakdown Spectroscopy under Gamma Irradiation"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T18:40:58.628235+00:00"}
