While performing the regular maintenance works (RMW) on the shutdown RBMK reactor it is required to provide reliable control condition of the core. This monitoring is made with the use of additional measurement tools in addition to basic. They are set only during RMW. Wire communication lines are most vulnerable when placing temporary equipment in the reactor reactor hall during the RMW. They can be damaged and interfere the staff to work. The intelligent measuring converters of physical parameters with a wireless data transmission channel was developed to control the temperature, level and pressure of the coolant, and to control the neutron flux density distribution in the core volume. Two types of wireless data transmission channels - optical (infrared) and radio were implemented. The choice of the radio channel type was justified. The advantages and disadvantages of each channel type are shown. The reactor parameters monitoring during RMW system was constructed on a basis of in-core mounted wireless "smart sensors". Now this system is being operated on power units of the Kursk nuclear power plant. The system composition and framework and its technical performance are considered. Measurements results are given and system operating experience on the nuclear power plant is discussed.
