Neutron Field for Activation Experiments in Horizontal Channel of Training Reactor VR-1

Popis výsledku v původním jazyce

The VR-1 training reactor of the Department of Nuclear Reactors of CTU in Prague is a light water swimming pool-type reactor with thermal power of 1 kWt. The reactor uses the IRT-4M-type concentric fuel moderately enriched to 19.7 % 235U. Since 1990, thereactor has served mostly to train students; the possibility to use the reactor for scientific purpose has been tested recently. It is equipped with several vertical and two horizontal channels that allow to study the neutron field and to irradiate samples. In present work, the feasibility of one of horizontal channels for irradiation application of materials and for nuclear data and calculation codes validation was successfully tested. The neutron multi-foil activation method was used to determine theneutron field parameters in the horizontal radial channel, namely the reaction rates, energy spectral indexes, and neutron spectrum. In the first experimental period, fourteen variable types of activation and threshold detectors (NaCl, A
