Abstract
ln the Jules Horowitz Reactor (JHR) experimental facilities will be available, including the
Light water One Rod Equipment for LOCA Experimental Investigations (LORELEI) device. ln
this work the thermohydraulics design of the LORELEI facility was developed with the code
CATHARE-2. The objective of the work was: to define a 3D geometry of the facility and to
verify the capacity of the system, under natural circulation, to remove the power generated
both by the fuel rod (up to 400 W/cm) and by gamma irradiation heating on the structures,
during the re-irradiation phase before the simulation of the high temperature transient. A
parametric calculation modifying several geometrical parameters was performed. The
parameters that should be varied were evaluate with an analytical approach. A final
geometry of the facility, able to work in natural circulation condition up to the maximum power
was selected. Further calculation was performed to analyze the correlation between the
accumulation of steam and the geometries of device at constant power.
