Validation of the Fast Neutron Field in the Radial Channel of the VR-1 Reactor

open access: closedJournal of Nuclear Engineering and Radiation Science, 2020
Abstract This work aims to characterize the neutron spectrum in the beam going out of the university research reactor (VR-1) using tubular-type of the nuclear fuel, version 4M (IRT-4M) fuel. Thanks to its variability, the core is often rearranged to fulfill different research tasks.

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

open access: closedSNA + 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.

Validation of the Serpent2 code for the VR-1 reactor core calculation

open access: closed2020 21st International Scientific Conference on Electric Power Engineering (EPE), 2020
The VR-1 reactor core safety characteristics calculations are performed by standardized MCNP code, however due to license requirements, it is desired to replace it by the Serpent2 code. In order to do that, Serpent2 calculation must be standardized by State office of nuclear safety.

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

open access: closedJournal 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

Research Reactor VR-1 and Determination of Neutron Spatial Distribution in Its Radial Experimental Channel

open access: closedVolume 4: Codes, Standards, Licensing and Regulatory Issues; Student Paper Competition, 2009
The research reactor VR-1 is operated by Faculty of Nuclear Sciences and Physical Engineering, Czech Technical University (CTU) in Prague. It is a pool-type, light-water reactor, with low enriched uranium. Maximum thermal power is 1kW (equal to 1·108 impulses/second when compared with reactors with higher power). Research on VR-1 reactor is mainly used

Effect of kinetics parameters on transients calculations in external source driven subcritical VR-1 reactor

open access: closedAnnals of Nuclear Energy, 2019
Abstract Kinetics parameters are of high importance for reactor transient analyses. Similarly, they play an important role in many experimental reactor techniques, especially in techniques for determination of reactivity (such as Source Jerk, Rod Drop, or Source Multiplication method).

Deterministic and stochastic neutron cross-section generation for PARCS applied to VR-1 reactor

open access: closed2016 17th International Scientific Conference on Electric Power Engineering (EPE), 2016
The VR-1 reactor operated by the Czech Technical University in Prague was utilized for a study of a macroscopic cross-sections homogenization performed by deterministic (SCALE 6.1.2 — Triton) and stochastic (Serpent 2.1.24) codes. These cross-sections are subsequently imported into a fixed source problem solved by the three-dimensional reactor core ...
