To reduce the nuclear data\u2013induced uncertainty of keff for a target system, this study investigates the applicability of data assimilation techniques, i.e., the bias factor method and the cross-section adjustment method, based on a subcritical measurement of \u03b1 conducted at Kyoto University Critical Assembly (KUCA). The sensitivity coefficients of keff and \u03b1 with respect to the nuclear data were efficiently estimated using a deterministic SN transport code with first-order perturbation theory. As a result, the a priori relative uncertainty of keff due to the 56-group SCALE covariance data can be reduced if there is strong correlation between the measured \u03b1 and the target keff. The experimental value of \u03b1 contributes to improving the nuclear data of total fission spectrum \u03c7 and total fission neutron number \u03bd via strong correlations between \u03c7 and prompt \u03c7p and between \u03bd and prompt \u03bdp, by utilizing the sensitivity coefficients of \u03b1 with respect to prompt \u03c7p and \u03bdp.","subitem_description_type":"Abstract"}]},"item_10_description_5":{"attribute_name":"\u5185\u5bb9\u8a18\u8ff0","attribute_value_mlt":[{"subitem_description":"Published online: 09 Mar 2020 \u30d5\u30a1\u30a4\u30eb\u516c\u958b\uff1a2021/03/09 \u30d5\u30a1\u30a4\u30eb\u5dee\u3057\u66ff\u3048\uff1a2021/06/25","subitem_description_type":"Other"}]},"item_10_publisher_32":{"attribute_name":"\u51fa\u7248\u8005","attribute_value_mlt":[{"subitem_publisher":"Taylor & Francis"}]},"item_10_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1080/00295639.2020.1720499","subitem_relation_type_select":"DOI"}}]},"item_10_rights_12":{"attribute_name":"\u6a29\u5229","attribute_value_mlt":[{"subitem_rights":"This is an Accepted Manuscript of an article published by Taylor & Francis Group in Nuclear Science and Technology on 09/03/2020, available online: http://www.tandfonline.com/10.1080/00295639.2020.1720499.","subitem_rights_language":"en"}]},"item_10_select_15":{"attribute_name":"\u8457\u8005\u7248\u30d5\u30e9\u30b0","attribute_value_mlt":[{"subitem_select_item":"author"}]},"item_10_source_id_61":{"attribute_name":"ISSN\uff08print\uff09","attribute_value_mlt":[{"subitem_source_identifier":"0029-5639","subitem_source_identifier_type":"PISSN"}]},"item_1615787544753":{"attribute_name":"\u51fa\u7248\u30bf\u30a4\u30d7","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_access_right":{"attribute_name":"\u30a2\u30af\u30bb\u30b9\u6a29","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"\u8457\u8005","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Endo, Tomohiro"}],"nameIdentifiers":[{"nameIdentifier":"101885","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamamoto, Akio"}],"nameIdentifiers":[{"nameIdentifier":"101886","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"\u30d5\u30a1\u30a4\u30eb\u60c5\u5831","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-06-25"}],"displaytype":"detail","filename":"NSE194_11_pp1089-1104_2020_r1.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://nagoya.repo.nii.ac.jp/record/30693/files/NSE194_11_pp1089-1104_2020_r1.pdf"},"version_id":"e48c6e38-95ba-4abf-8707-7f3e8562e809"}]},"item_keyword":{"attribute_name":"\u30ad\u30fc\u30ef\u30fc\u30c9","attribute_value_mlt":[{"subitem_subject":"Prompt neutron decay constant","subitem_subject_scheme":"Other"},{"subitem_subject":"Feynman-\u03b1 method","subitem_subject_scheme":"Other"},{"subitem_subject":"perturbation theory","subitem_subject_scheme":"Other"},{"subitem_subject":"bias factor method","subitem_subject_scheme":"Other"},{"subitem_subject":"cross-section adjustment method","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"\u8a00\u8a9e","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"\u8cc7\u6e90\u30bf\u30a4\u30d7","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Data Assimilation Using Subcritical Measurement of Prompt Neutron Decay Constant","item_titles":{"attribute_name":"\u30bf\u30a4\u30c8\u30eb","attribute_value_mlt":[{"subitem_title":"Data Assimilation Using Subcritical Measurement of Prompt Neutron Decay Constant","subitem_title_language":"en"}]},"item_type_id":"10","owner":"17","path":["320/321/322"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2020-10-26"},"publish_date":"2020-10-26","publish_status":"0","recid":"30693","relation_version_is_last":true,"title":["Data Assimilation Using Subcritical Measurement of Prompt Neutron Decay Constant"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2021-06-25T06:54:24.154391+00:00"}
