New Control System of VR-1 Training Reactor
Volume 2: Nuclear Policy; Nuclear Safety, Security, and Cyber Security; Operating Plant Experience; Probabilistic Risk Assessments; SMR and Advanced Reactors, 2021 Abstract The VR-1 training reactor with 500W maximum power operates at the Czech Technical University in Prague. Its control system was approaching obsolescence. It was therefore decided to upgrade the control system using up-to-date hardware and software using a new industrial PC with Windows 10 and the RTX real time system. The control

Validation of the Fast Neutron Field in the Radial Channel of the VR-1 Reactor [PDF]
Journal 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.

Characterization of mixed N/G beam of the VR-1 reactor
Annals of Nuclear Energy, 2018 Abstract VR-1 is light water zero-power reactor using IRT-4 M fuel with nominal enrichment of 19.7 wt%, equipped with the radial channel being directly attached to the fuel. Enrichment at the top level of the low enriched uranium limit guarantees that the larger part of non-scattered neutrons in the spectrum is coming from 235U than in case of ...

Experimental studio data acquisition system at VR-1 reactor
2016 17th International Scientific Conference on Electric Power Engineering (EPE), 2016 The VR-1 reactor is operated by the Czech Technical University in Prague more than 20 years. The reactor is utilized mainly for education and training purposes. Therefore, the Czech Technical University, as a reactor licensee, makes an effort to continuously improve the reactor equipment, instrumentation and the educational and training methodologies ...

Annals of Nuclear Energy, 2018 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).

Neutronic design of instrumentation for thermal effects measurement on VR-1 reactor
2009 1st International Conference on Advancements in Nuclear Instrumentation, Measurement Methods and their Applications, 2009 At the Czech Technical University (CTU) in Prague a new instrumentation for measurement of thermal effects is currently designed for the use on the training reactor VR-1 “Sparrow”. The instrumentation is designed to serve both for the purposes of education and training and RD in the latter case especially for the examination of possible precision and ...

Manual control during reactivity transients at the VR-1 reactor – I. Disturbance rejection
Nuclear Engineering and Design, 2017 Abstract The description of human operator dynamic characteristics in mathematical terms compatible with control engineering practice is an essential prerequisite to the analytical treatment of manual reactor control systems. Safe reactor operation requires effective operator control through interaction with plant dynamics, manipulators and displays.
