Abstract: Under the China-EU corporation project Supercritical Water Reactor-Fuel Qualification Test (SCWR-FQT), a configuration of the LVR-15 core with the SCWR-FQT facility was constructed to study the impact of supercritical water on the loops designing. The neutron physical analysis of the core and facility is the premise of thermal analysis and designing of the loops. RMC code which was developed by Department of Engineering Physics, Tsinghua University as a tool for reactor physical analysis was used to analyze the LVR-15 core and SCWR-FQT facility. Criticality calculating was performed, and the fuel enrichment, whole core neutron flux distribution and neutron spectrum and neutron flux of the supercritical facility were obtained, based on which the burnup calculation and analysis of the core and FQT facility were completed.
