Application of the Source-Jerk method using a neutron generator in a subcritical reactor
Acta Polytechnica, 2023 This paper describes the application of the Source-Jerk method using a neutron generator in the VR-1 reactor. The experiments were carried out on a shutdown reactor with subcriticality greater than -10 βeff.

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.

Calculation and measurement of Al prompt capture gammas above water in a pool-type reactor
Nuclear Engineering and Technology, 2022 Prompt capture gammas are an important part of the fission reactor gamma field. Because some of the structural materials after neutron capture can emit photons with high energies forming the dominant component of the gamma spectrum in the high energy ...

Neutron imaging on the VR-1 reactor
Journal of Physics: Conference Series, 2016 Training reactor VR-1 is a low power research reactor with maximal thermal power of 1 kW. The reactor is operated by the Faculty of Nuclear Science and Physical Engineering of the Czech Technical University in Prague. Due to its low power it suits as a tool for education of university students and training of professionals.
