“…The former pitfall is more typical for an unexperienced code user, whereas the latter is more frequently experienced by more skilled users who are, nevertheless, not acquainted with the entire structure and features of the computational model. There is, however, an example of [11], who demonstrate ratios in the same range as presented by developers as well as those in agreement with the benchmark. We can explain this as being due to the substantial experience of that particular group in computer simulations (even if they are not developers of the codes used in their paper).…”

Monte-Carlo nuclear reaction and transport codes are widely used to devise accelerator-based nuclear physics experiments; at the same time, many experiments are performed to validate the Monte-Carlo codes, which can be used for the design of full-scale nuclear power applications or the design of new benchmark experiments. Dedicated model benchmark studies investigate a broad range of nuclear reactions and quantities. Examples of these include isotope formation or secondary particle fluxes that result from the interactions of GeV-range hadrons with monoisotopic targets, which can be used to assess the respective systematic uncertainty of models. Such benchmark studies, as well as many nuclear application experiments and simulations carried out by various groups over the last few decades, enable us to draw methodological lessons. In this work, model uncertainty determined based on available experimental data allow us to identify the effects of practitioner expertise as well as the design of codes (user access to micro-scale parameters) on the range of uncertainties. We found that in cases when simulations are performed by code developers or users that are very experienced in performing simulations, the model to experiment quantity ratios generally agree with the limits determined by dedicated benchmark studies. In other cases, the ratios generally tend to be either smaller (underestimation of model error) or larger (overestimation of model error). A plausible explanation of the aforementioned effects is suggested.

In 2011-2017 in the framework of the international collaboration project “Energy and Transmutation of RAW”, a series of experimental studies on the deep subcritical uranium assembly QUINTA were carried out. The massive uranium target (512 kg of natU) was irradiated with 0.66 GeV proton, deuterons and 12C nuclei (1 to 4 AGeV) from the Phasotron and Nuclotron accelerators (JINR, Dubna). The main results of experimental studies carried out with the participation of the Kharkov group of collaboration are presented.

“…The problem of recovery of long-lived radioactive nuclear waste, including plutonium, minor actinides, and other fission products, is important in nuclear technology; it has been studied at most accelerator complexes worldwide. These studies point to a possibility of recovering long-lived radioactive waste in high intensity neutron beams [11]. The creation of a full-scale acceleratorcontrolled reactor facility for power production and transmutation of long-lived radioactive isotopes, experimental measurements of cross sections in an energy range up to several GeV/nucleon are required.…”
