To directly measure α in a target critical system, this study proposes the application of the dynamic mode decomposition (DMD) to the reactor noise analysis based on the Rossi-α method. The DMD-based Rossi-α method enables us to robustly estimate the fundamental mode component of α from the Rossi-α histograms measured using multiple neutron detectors. Furthermore, the file-by-file moving block bootstrap method is newly proposed for the statistical uncertainty quantification of α to prevent huge memory usage when the neutron count rate is high and/or the total measurement time is long. A critical experiment has been conducted at Kyoto University Critical Assembly to demonstrate the proposed method. As a result, the proposed method can uniquely determine the α value of which the statistical uncertainty is smallest. By utilizing this experimental result of α, numerical results of βeff/ℓ ratio using the continuous energy Monte Carlo code MCNP6.2 with recent nuclear data libraries, which are processed by the nuclear data processing code FRENDY, are validated.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}, {"subitem_description": "Published online: 27 Feb 2022", "subitem_description_language": "en", "subitem_description_type": "Other"}]}, "item_9_publisher_32": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "Taylor \u0026 Francis", "subitem_publisher_language": "en"}]}, "item_9_relation_43": {"attribute_name": "関連情報", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "https://doi.org/10.1080/00223131.2022.2030260", "subitem_relation_type_select": "DOI"}}]}, "item_9_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 Journal of Nuclear Science and Technology on 27/02/2022, available online: http://www.tandfonline.com/10.1080/00223131.2022.2030260.", "subitem_rights_language": "en"}]}, "item_9_source_id_7": {"attribute_name": "収録物識別子", "attribute_value_mlt": [{"subitem_source_identifier": "0022-3131", "subitem_source_identifier_type": "PISSN"}]}, "item_access_right": {"attribute_name": "アクセス権", "attribute_value_mlt": [{"subitem_access_right": "embargoed access", "subitem_access_right_uri": "http://purl.org/coar/access_right/c_f1cf"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Endo, Tomohiro", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Nishioka, Fuga", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Yamamoto, Akio", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Watanabe, Kenichi", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Pyeon, Cheol Ho", "creatorNameLang": "en"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2023-02-27"}], "displaytype": "detail", "download_preview_message": "Download / Preview is available from 2023/2/26.", "file_order": 0, "filename": "JNST59_9_pp1117-1126_2022.pdf", "filesize": [{"value": "682 KB"}], "format": "application/pdf", "future_date_message": "Download is available from 2023/2/26.", "is_thumbnail": false, "mimetype": "application/pdf", "size": 682000.0, "url": {"objectType": "fulltext", "url": "https://nagoya.repo.nii.ac.jp/record/2003808/files/JNST59_9_pp1117-1126_2022.pdf"}, "version_id": "bbc432e0-cacf-482a-be36-105c5f1bdf19"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Prompt neutron decay constant", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Rossi-α method", "subitem_subject_scheme": "Other"}, {"subitem_subject": "critical experiment", "subitem_subject_scheme": "Other"}, {"subitem_subject": "dynamic mode decomposition", "subitem_subject_scheme": "Other"}, {"subitem_subject": "bootstrap method", "subitem_subject_scheme": "Other"}, {"subitem_subject": "KUCA", "subitem_subject_scheme": "Other"}, {"subitem_subject": "validation", "subitem_subject_scheme": "Other"}, {"subitem_subject": "JENDL", "subitem_subject_scheme": "Other"}, {"subitem_subject": "FRENDY", "subitem_subject_scheme": "Other"}, {"subitem_subject": "MCNP", "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": "Application of dynamic mode decomposition to Rossi-α method in a critical state using file-by-file moving block bootstrap method", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Application of dynamic mode decomposition to Rossi-α method in a critical state using file-by-file moving block bootstrap method", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "17", "path": ["322"], "permalink_uri": "http://hdl.handle.net/2237/0002003808", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2022-09-26"}, "publish_date": "2022-09-26", "publish_status": "0", "recid": "2003808", "relation": {}, "relation_version_is_last": true, "title": ["Application of dynamic mode decomposition to Rossi-α method in a critical state using file-by-file moving block bootstrap method"], "weko_shared_id": -1}
