“…An important task when testing model fuel elements and fuel assemblies in the IGR reactor is the implementation of a given power release. It, with high accuracy, is provided thanks to a number of developed methods which are aimed for the determining the tests energy parameters [5,6], location and mass of fuel composition inside the test device [7,8] and impurity gas releasing from the fuel during the irradiation [9]. IGR technical possibilities as well as the developed methodical base made it possible to launch the ambitious international experimental programs EAGLE (Experimental Acquisition of Generalized Logic to Eliminate re-criticalities) [10,11] and SAIGA (Severe Accident In-pile experiments for Gen-IV reactors and the Astrid prototype) [12].…”

The article presents the results of computational studies to substantiate the possibility of testing the fuel of the Multipurpose hYbrid Research Reactor for a High-tech Applications reactor (MYRRHA) in the Impulse Graphite research Reactor (IGR). A scheme for conducting experiments is proposed, which allows simulating the operating conditions of MYRRHA fuel elements in a wide range of changes in their thermohydraulic parameters, including the conditions of accidents with the destruction of fuel pellets, blocking the flow area and stopping the coolant flow. A method for thermohydraulic calculations has been developed, implemented in the software environment of the computational fluid dynamics (CFD) code. A computational model of the experimental device is developed, optimized according to the spatial partitioning grid. A turbulence model for determining the parameters of convective heat and mass transfer in a eutectic lead-bismuth alloy is selected and substantiated.
