Calculations and Measurements at the Training Reactor VR-1

The Paper describes basic information about MCNP calculations and experimental measurements at the VR-1 reactor and their evaluation. The preparation of calculations and verification of the experiments are integral part of the VR-1 reactor operation. The neutronics calculations and analyses are often necessary condition to gain the approval to experiments realization at the reactor VR-1. The paper is focused particularly on the calculations and experiments with the LEU fuel core configuration.
