Abstract

The Refueling Neutron Monitoring System and the Reactivity Monitoring System for startup measurements are both aged, the development of a new combined system fulfilling both functionalities has therefore been started. The new system is based on 6 autonomous measurement chains covering the whole neutron flux range and uses fixed fission chambers. The signals of the measurement chains are received by two redundant processing systems continuously providing measured and calculated data for external systems like the VERONA core monitoring system. The system generates emergency signals and events for the operators of the Main Control Room and the Refueling Machine. The pilot measurement chain has been tested at Units 2 and 3 of Paks NPP. The first implementation of the new system is planned to be installed at Unit 3 by the middle of the following year.
