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 \u0026 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 \u0026 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", "download_preview_message": "", "file_order": 0, "filename": "NSE194_11_pp1089-1104_2020_r1.pdf", "filesize": [{"value": "1.2 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "mimetype": "application/pdf", "size": 1200000.0, "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"], "permalink_uri": "http://hdl.handle.net/2237/00032880", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2020-10-26"}, "publish_date": "2020-10-26", "publish_status": "0", "recid": "30693", "relation": {}, "relation_version_is_last": true, "title": ["Data Assimilation Using Subcritical Measurement of Prompt Neutron Decay Constant"], "weko_shared_id": -1}
