Supporting Economic and Efficient Operation of NPPs
We provide a number of activities to NPP operators aimed at increasing the efficiency and reliability of the plant units. As part of our comprehensive projects to boost performance, we have references at the level of general contractors.
Support of the economic and efficient operation of NPPs includes a broad range of activities and tools, in particular:
Comprehensive power uprate projects of VVER reactor units;
Demonstration of sufficient margins for safe and reliable operation of power up-rated units, taking into account the requirements for long-term operation (LTO);
Completion of plant safety documentation, including safety reports;
Support for the operator regarding licensing;
Support for the communication of utility with regulatory bodies.
Analyses and proposals for modifying existing procedures to improve efficiency of plant operation;
Optimization of the fuel cycle and fuel reloads in terms of efficient use of nuclear fuel;
Optimizing device parameters for new operating conditions;
Development of project documentation of operating modes, units maneuverability and ability to perform support services for the transmission grids;
Risk-based optimization of plant shutdown schedules;
Reliability based maintenance programs;
Optimization of corrective actions and modifications in NPP operation, evaluation of impacts of modifications of equipment on NPP operation;
