New Human-Machine Interface at VR-1 Training Reactor

18th International Conference on Nuclear Engineering: Volume 1, 2010
The paper describes a new human-machine (HMI) interface of the VR-1 nuclear training reactor at the Czech Technical University in Prague. The VR-1 reactor is primarily used for training of university students and future nuclear power plant staff. The new HMI was designed to meet functional, ergonomic and aesthetic requirements.

Measurement of the selected spectral averaged cross sections in a radial channel of the VR-1 reactor

Applied Radiation and Isotopes, 2019
The spectral averaged cross section is an important quantity used in a validation of nuclear cross section. When the cross sections are averaged over the neutron standard field (252Cf(s,f) or 235U(n,f) neutron spectrum), they can be used for tuning of evaluations.

Neutron field for activation experiments in horizontal channel of training reactor VR-1

Radiation Physics and Chemistry, 2014
Abstract The experimental channels of nuclear reactors often serve for nuclear data measurement and validation. The dosimetry-foils activation technique was employed to measure neutron field parameters in the horizontal radial channel of the training reactor VR-1, and to test the possibility of using the reactor for scientific purposes.
