By utilizing numerical results of keff for critical benchmark-problems that are selected depending on neutronic similarity to the application system, the ECLLMF should be carefully and conservatively estimated based on uncertainties of keff due to a criticality safety analysis code, experimental uncertainty, and covariance matrix of the nuclear data library. Furthermore, the frequency distribution of keff for these problems does not necessarily obey an ideal normal distribution. Using a resampling technique called \u2018bootstrap method,\u2019 the proposed method can reasonably estimate the ECLLMF considering the uncertainties and nuclear data-induced correlation between each critical benchmark-problem without the assumption of normality. To investigate the applicability of the proposed method, the approach-to-criticality experiment was carried out at the Kyoto University Critical Assembly (KUCA). Comparison of numerical results of keff and the ECLLMF using the bootstrap method indicated that the proposed method was able to judge an actual subcritical core as subcritical state.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}, {"subitem_description": "Published online: 30 Jun 2021", "subitem_description_language": "en", "subitem_description_type": "Other"}]}, "item_9_publisher_32": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "Taylor \u0026 Francis", "subitem_publisher_language": "en"}]}, "item_9_relation_43": {"attribute_name": "\u95a2\u9023\u60c5\u5831", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "https://doi.org/10.1080/00223131.2021.1902416", "subitem_relation_type_select": "DOI"}}]}, "item_9_rights_12": {"attribute_name": "\u6a29\u5229", "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 30/06/2021, available online: http://www.tandfonline.com/10.1080/00223131.2021.1902416.", "subitem_rights_language": "en"}]}, "item_9_source_id_7": {"attribute_name": "\u53ce\u9332\u7269\u8b58\u5225\u5b50", "attribute_value_mlt": [{"subitem_source_identifier": "0022-3131", "subitem_source_identifier_type": "PISSN"}]}, "item_access_right": {"attribute_name": "\u30a2\u30af\u30bb\u30b9\u6a29", "attribute_value_mlt": [{"subitem_access_right": "embargoed access", "subitem_access_right_uri": "http://purl.org/coar/access_right/c_f1cf"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Hayashi, Takuto", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Endo, Tomohiro", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Yamamoto, Akio", "creatorNameLang": "en"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2022-06-30"}], "displaytype": "detail", "download_preview_message": "Download / Preview is available from 2022/6/29.", "file_order": 0, "filename": "JNST58_pp1008-1017_2021.pdf", "filesize": [{"value": "739 KB"}], "format": "application/pdf", "future_date_message": "Download is available from 2022/6/29.", "is_thumbnail": false, "mimetype": "application/pdf", "size": 739000.0, "url": {"objectType": "fulltext", "url": "https://nagoya.repo.nii.ac.jp/record/2001469/files/JNST58_pp1008-1017_2021.pdf"}, "version_id": "a801654a-a269-4a81-a7e9-4156e082b5e6"}]}, "item_keyword": {"attribute_name": "\u30ad\u30fc\u30ef\u30fc\u30c9", "attribute_value_mlt": [{"subitem_subject": "subcriticality", "subitem_subject_scheme": "Other"}, {"subitem_subject": "estimated criticality lower-limit multiplication factor", "subitem_subject_scheme": "Other"}, {"subitem_subject": "bootstrap method", "subitem_subject_scheme": "Other"}, {"subitem_subject": "critical experiment", "subitem_subject_scheme": "Other"}, {"subitem_subject": "KUCA", "subitem_subject_scheme": "Other"}, {"subitem_subject": "uncertainty", "subitem_subject_scheme": "Other"}, {"subitem_subject": "criticality calculation", "subitem_subject_scheme": "Other"}, {"subitem_subject": "covariance", "subitem_subject_scheme": "Other"}, {"subitem_subject": "nuclear data", "subitem_subject_scheme": "Other"}, {"subitem_subject": "benchmark", "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": "Proposal and applicability of estimated criticality lower-limit multiplication factor using the bootstrap method", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "Proposal and applicability of estimated criticality lower-limit multiplication factor using the bootstrap method", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "17", "path": ["320/321/322"], "permalink_uri": "http://hdl.handle.net/2237/0002001469", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2021-09-17"}, "publish_date": "2021-09-17", "publish_status": "0", "recid": "2001469", "relation": {}, "relation_version_is_last": true, "title": ["Proposal and applicability of estimated criticality lower-limit multiplication factor using the bootstrap method"], "weko_shared_id": -1}
