The Shielding INtegral Benchmark Archive and Database (SINBAD) project was presented which was started in the early 1990’s at the OECD Nuclear Energy Agency Data Bank (NEA DB) and the Radiation Safety Information Computational Center (RSICC) with the objective to preserve and disseminate the information on the quality experiments for validating and benchmarking computer codes and nuclear data for radiation transport and shielding applications. Currently, the SINBAD database comprises over 100 benchmark compilations and evaluations of relevance to: • reactor shielding, pressure vessel dosimetry (48) • fusion blanket neutronics (31) • accelerator shielding (23).

COBISS.SI-ID: 2870628The rod insertion method presents an efficient way of measuring the reactivity worth of control rods in a nuclear reactor. This is an inherently dynamic method, which is why we highlighted the differences between the static and the dynamic reactivity. Direct comparison of results based on the static and the dynamic reactivity relies heavily on adequate time-resolved three-dimensional numerical simulation. In the present work, this is achieved by updating the Gnomer computer program to support such calculation and verifying it on representative test cases. In the following, improvements of the rod insertion method are based on experimental data from the Krško nuclear power plant. Due to the results of the analysis, some of the methodological assumptions are retained (e.g. continuous insertion), while others are ameliorated (e.g. flux redistribution correction). A new correction is added, namely the reactivity overshoot compensation. It takes into account the dynamic effects after the control rod has reached its fully inserted state, and as such increases the total rod worth measurement consistency. Lastly, conversion from dynamic to static reactivity worth is established by following the examples in the literature and by using kinetic simulation. Thus – with the updated methodology – the rod insertion method is proven to yield excellent results in comparison to the well-established boron dilution method, and can be used as replacement. Prof. dr. Andrej Trkov was also doctoral dissertation mentor to dr. Dušan Čalič, who successfully defended his doctoral dissertation in 2016 (COBISS ID: 19753750)

COBISS.SI-ID: 287973376Researchers from the reactor physics division at the Jožef Stefan Institute have been actively involved in the project International Criticality Safety Benchmark Evaluation Project (ICSBEP) for more than 10 years. The purpose of ICSBEP is to collect, evaluate, and publish all important reactor physics experiments that have been performed in various laboratories from all over the world. The work of ICSBEP is documented as an International Handbook of Evaluated Criticality Safety Benchmark Experiments. Currently, the handbook spans over 50,000 pages and contains more than 4000 experimental configurations. The ICSBEP working group has 50-70 members, all of them top-level experts in reactor physics.
