Abstract
The measuring system for the in-reactor control of energy release over the reactor core volume by activating copper wire indicators in the “dry” channels of the VK-50 reactor (State Scientific Center Research Institute of Atomic Reactors) has been re-equipped including the modernization of both hardware and software and methodological parts. One of the reasons for the transition to a new measuring system was a rather large discrepancy in the measurement results when using the old equipment, both in the level of activity and in the form of distribution of activations between measurements. The results of the modernization have been presented. Changes both in the methodological measuring part and in the software processing of the measurement results with the determination of the distribution of energy release over the volume of the reactor core have been described. Information on test calculations of the previous calculation program and the new one is given. The final stage of verifying the operability of the scanning equipment of copper wire indicators was a comparison of the calculated and experimental data. As a result of the modernization, the CUPRUM program has been developed, involving the modern operating conditions of the reactor core and the types of computer equipment used. The measuring equipment for scanning the copper wire indicator has been replaced with a more modern one.
