The&nbsp;analysis has been performed using the TRACE system code&nbsp;modified for the fast reactor applications using a point kinetics neutronics model and 1D multichannel<br> thermal-hydraulic model. The SPX start-up core&nbsp;benchmark specification was used&nbsp;for calculation of neutron physics data employed as input in&nbsp;the TRACE simulations. The analysis covered transient&nbsp;simulation before sodium boiling onset. The influence of&nbsp;control rod drive lines (CRDL) expansion reactivity effect on&nbsp;the grace time before boiling was found to be significant.&nbsp;Series of calculations have been performed in order to assess&nbsp;sensitivity of the results to the core specification data and&nbsp;modelling details in both thermal hydraulics and neutronics&nbsp;inputs. In particular, two different models representing fuel&nbsp;subassemblies (three-channel and multichannel) have been&nbsp;employed. In addition, the influence of reactivity effects&nbsp;uncertainty on transient behaviour has been assessed, as well&nbsp;as sensitivity of the results to account for the spatial&nbsp;distribution of reactivity effects in the core. The results of this&nbsp;study serve further as a basis for the transient benchmark&nbsp;exercise proposed by Ponomarev, et al., 2018 within the&nbsp;framework of the Horizon-2020 ESFR-SMART project.</p></dct:description> <dct:accessRights rdf:resource="http://publications.europa.eu/resource/authority/access-right/PUBLIC"/> <dct:accessRights> <dct:RightsStatement rdf:about="info:eu-repo/semantics/openAccess"> <rdfs:label>Open Access</rdfs:label> </dct:RightsStatement> </dct:accessRights> <dct:license rdf:resource="https://creativecommons.org/licenses/by/4.0/legalcode"/> <dcat:distribution> <dcat:Distribution> <dcat:accessURL rdf:resource="https://doi.org/10.5281/zenodo.3262074"/> <dcat:byteSize>1449797</dcat:byteSize> <dcat:downloadURL rdf:resource="https://zenodo.org/record/3262074/files/2019.05_Ponomarev_ICONE.pdf"/> <dcat:mediaType>application/pdf</dcat:mediaType> </dcat:Distribution> </dcat:distribution> </rdf:Description> <foaf:Project rdf:about="info:eu-repo/grantAgreement/EC/H2020/754501/"> <dct:identifier rdf:datatype="http://www.w3.org/2001/XMLSchema#string">754501</dct:identifier> <dct:title>European Sodium Fast Reactor Safety Measures Assessment and Research Tools</dct:title> <frapo:isAwardedBy> <foaf:Organization> <dct:identifier rdf:datatype="http://www.w3.org/2001/XMLSchema#string">10.13039/100010661</dct:identifier> <foaf:name>European Commission</foaf:name> </foaf:Organization> </frapo:isAwardedBy> </foaf:Project> </rdf:RDF>
