Enhancement of liquid/gas production during co-pyrolysis of vacuum residue and plastics due to synergistic interactions [PDF]
Scientific ReportsVacuum residue (VR) was copyrolysed with polyethylene (PE) or polystyrene (PS) in a batch reactor to investigate the corresponding synergistic pyrolytic interactions. The synergistic interactions between VR and plastic pyrolysates enhanced liquid and gas

Utilization of a zero power reactor for examination of operator influence on reactor control [PDF]
EPJ Web of Conferences, 2020 The reactor operator is an inseparable part of reactor safety and his actions influence the course of the reactor transients. Understanding the operator’s effect on reactor control thus contributes to the knowledge of the safe operation of nuclear ...

Measurement of prompt gamma field above the VR-1 water level [PDF]
EPJ Web of Conferences, 2021 Pool-type reactors are an excellent source of high energy photons without neutrons because the water above fuel acts as an outstanding neutron shielding, whereas for high energy photons, it is nearly transparent.
