Application of MCNP for neutronic calculations at VR-1 training reactor

SNA + MC 2013 - Joint International Conference on Supercomputing in Nuclear Applications + Monte Carlo, 2014
The paper presents utilization of Monte Carlo MCNP transport code for neutronic calculations of training reactor VR-1. Results of calculations are compared with results of measurements realized during last few critical experiments with various reactor core configurations. Very good agreement between calculations and measurements is observed.

Calibration of new I&C at VR-1 training reactor

Nuclear Engineering and Design, 2011
The paper describes a calibration of the new instrumentation and control (I&C) at the VR-1 training reactor in Prague. The I&C uses uncompensated fission chambers for the power measurement that operate in a pulse or a DC current and a Campbell regime, according to the reactor power.

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.

Study of dietary supplements compositions by neutron activation analysis at the VR-1 training reactor

Radiation Physics and Chemistry, 2017
Abstract The VR-1 training reactor operated by the Czech Technical University in Prague is utilized mainly for education of students and training of various reactor staff; however, RD each brand is represented by several different batches of pills. All pills were irradiated together with the standard activation etalons in the vertical channel of the ...

Neutron Activation Analysis of Environmental Samples at the Training Reactor VR-1

Journal of Nuclear Engineering and Radiation Science
Abstract Described research work is focused on the study of environmental pollution in the Czech Republic using an instrumental neutron activation analysis (INAA). The samples of mosses and alluvial soils were irradiated at the VR-1 training reactor utilizing a nondestructive (instrumental) method of NAA at the Czech Technical University
