In order to define the helium refrigerator requirements for the superconducting coil system, their thermal protection and the cryopumps, heat loads at different temperature levels have been defined. Because of plasma pulse operation, transient heat pulses appear at the 4 K level for the superconducting coils and the cold structures as well as at the divertor cryopumps of JT-60SA.\nSince the heat loads were calculated at an earlier stage of the project, the loads of each component design had a certain amount of uncertainty. In JT-60SA, an attempt was made to define reasonable contingencies for the heat load by applying Monte Carlo simulation and put the 99% confidence value of the heat load as requirement for the refrigerator. Exergy analysis of heat loads at different temperatures and the helium mass flows of the JT-60SA resulted in an equivalent refrigeration power of about 9 kW at 4.5 K. This paper summarizes all the thermal analyses performed to determine the refrigeration power of the JT60SA helium refrigerator.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"ELSEVIER"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.cryogenics.2019.02.008","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.sciencedirect.com/science/article/abs/pii/S0011227518303084","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0011-2275","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"神谷, 宏治"}],"nameIdentifiers":[{"nameIdentifier":"825137","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"夏目, 恭平"}],"nameIdentifiers":[{"nameIdentifier":"825138","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"福井, 良磨"}],"nameIdentifiers":[{"nameIdentifier":"825139","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"村上, 陽之"}],"nameIdentifiers":[{"nameIdentifier":"825140","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"木津, 要"}],"nameIdentifiers":[{"nameIdentifier":"825141","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"礒野, 高明"}],"nameIdentifiers":[{"nameIdentifier":"825142","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Wanner, Manfred"}],"nameIdentifiers":[{"nameIdentifier":"825143","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kamiya, Koji","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"825144","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Natsume, Kyohei","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"825145","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Fukui, Kazuma","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"825146","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Murakami, Haruyuki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"825147","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kizu, Kaname","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"825148","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Isono, Takaaki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"825149","nameIdentifierScheme":"WEKO"}]}]},"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":"Summary of thermal analyses to determine the refrigeration power for the JT-60SA helium refrigerator","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Summary of thermal analyses to determine the refrigeration power for the JT-60SA helium refrigerator"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-03-01"},"publish_date":"2019-03-01","publish_status":"0","recid":"74618","relation_version_is_last":true,"title":["Summary of thermal analyses to determine the refrigeration power for the JT-60SA helium refrigerator"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:11:52.977640+00:00"}
