Benchmark consolidated results against experimental data from SPERT IV statics

Abstract

The IAEA CRP (CRP 1496) on ‘Benchmarking, against Experimental Data, of the Neutronic and Thermalhydraulic Computational Methods and Tools for Operation and Safety Analysis for Research Reactors’ provides a unique opportunity to benchmark and compare the accuracy and efficiency of both off-the-shelf and locally developed computational tools to a wide set of experimental research reactor benchmark analysis. In the scope of this project, various analysis groups have evaluated the SPERT IV benchmark analysis – consisting of a variety of commissioning experiments and multiple sets of Reactivity Insertion Accident (RIA) measurements. This report is focused on the commissioning experiments and associated measurements, referred to herein as the ‘Statics’ or neutronic section of the SPERT IV benchmark analysis. It summarizes and compares the analysis methodologies adopted, the code systems employed, and the simulation results generated by the various analysis groups. A comparison of the computational results to available experimental results is also provided in this report. © 2019 The Authors
