In 2014, the Novovoronezh NPP, VNIIAES and JSC «Innovative firm SNIIP-Atom» took the decision to develop the system of intellectual support of the operator (SIPO). The main purpose of the SIPO is the implementation of an important function for the safe and reliable operation of NPP equipment – the possibility of analyzing the process in real time and its projection in the future, which allows issuing recommendations to the operator on the optimal process control, especially in situations with limited time for decision-making.

As part of the development of the SIPO, a software model of nuclear power unit was created as part of the upper-level system (IAS) of the Novovoronezh NPP-2 Unit 1, and step-by-step interactive procedures (IP) for managing operating processes of the power unit are being developed.

For reducing the load on the operator when performing complex switching on the equipment, the SIPO supported with IP must ensure the following: – Continuous transmission of information about the status of the nuclear power plant, the dynamics of variables essential for ensuring safety and efficiency of the equipment collected from the automated control system of technological processes (ACSTP) of the unit; – Issuance of the analyzed information to the operator in the form convenient for making management decisions in the control of the technological process; – Immediate notification of all stakeholders about the current status of the power plant and planned operations.

SP for Unit 1 of the Novovoronezh NPP-2 start-up is examined as an illustration of the possibilities of interactive procedures and solutions to the problems of reducing the load on the operator. The SP allowing online control and management of the NPP unit start-up process is developed for the first time. Starting up Russian NPP units was performed previously strictly based on the approved hard copy of the program of the power unit start-up, which is associated with a number of significant drawbacks.
