The article shows the importance of additional information support for the NPP operation and emergency and crisis control centers involvement taking into account the safety of operation as the highest priority. Emergency control tools used at Russian nuclear power plants allows to obtain the nuclear power plant operational information outside the automated control system for these purposes. The main consumer of such information is the JSC Rosenergoatom Concern Crisis Center, its capabilities allow regular exercises with modeling of emergency situations at nuclear power plants and working out the actions of personnel. There have been significant changes in the operating systems market in Russia recently, a number of regulatory documents have been issued that include additional requirements from the point of view of information security to obtain data from automated control systems. Rostov NPP has been successfully operating a system of process parameter presentation for more than 20 years, it provides the operation engineering support personnel and crisis centres with all necessary information on the safety of power units in real time. Considering the Rostov NPP experience, the need to develop a new generation of means of transmitting and presenting technological information to the automated control systems of NPP power units is shown. Possible options to overcome the existing limitations are considered in the paper. It proposes a scenario of development and implementation of means of transmission and presentation of technological information at Rostov NPP, including a number of specific functions. The Rostov NPP experience in developing a new generation of means of important technology information transmission and presentation can be replicated at other Russian nuclear power plants.
