Experiment-Based Verification of the SAFR/V1 Module of the EVKLID/V2 Integral Code for Thermal Breakdown of Fuel Pins in a Fast Reactor

Abstract

The results of verification of the IBRAE-developed SAFR/V1 module, describing in the EVKLID/V2 integral code the thermal breakdown of fuel pins, on the basis of data obtained using experimental facilities. The experiments performed on the TREAT and DEH facilities at the Argonne National Laboratory and on a bench at the Nizhny Novgorod State Technical University were picked for the verification process. The computational error was evaluated for individual parameters on the basis of the verification results. The impact of the uncertainties in the initial data on the computational results was analyzed.
