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

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

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