To reduce the nuclear data–induced 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 α conducted at Kyoto University Critical Assembly (KUCA). The sensitivity coefficients of keff and α 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 α and the target keff. The experimental value of α contributes to improving the nuclear data of total fission spectrum χ and total fission neutron number ν via strong correlations between χ and prompt χp and between ν and prompt νp, by utilizing the sensitivity coefficients of α with respect to prompt χp and νp.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"Published online: 09 Mar 2020 ファイル公開：2021/03/09 ファイル差し替え：2021/06/25","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_10_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Taylor & Francis","subitem_publisher_language":"en"}]},"item_10_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","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":"権利","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":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"author"}]},"item_10_source_id_61":{"attribute_name":"ISSN（print）","attribute_value_mlt":[{"subitem_source_identifier":"0029-5639","subitem_source_identifier_type":"PISSN"}]},"item_1615787544753":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Endo, Tomohiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"101885","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamamoto, Akio","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"101886","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","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":"キーワード","attribute_value_mlt":[{"subitem_subject":"Prompt neutron decay constant","subitem_subject_scheme":"Other"},{"subitem_subject":"Feynman-α 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":"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":"Data Assimilation Using Subcritical Measurement of Prompt Neutron Decay Constant","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Data Assimilation Using Subcritical Measurement of Prompt Neutron Decay Constant","subitem_title_language":"en"}]},"item_type_id":"10","owner":"1","path":["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":"1","weko_shared_id":-1},"updated":"2023-01-16T04:57:42.501970+00:00"}
