This article is regarded to the search for the best power control program at nuclear power plant (NPP) with VVER-1000 by gradient descent method for the objective function, which includes the criteria of efficiency, safety and damage.
Criteria normalization to the maximum value is carried out when looking for the minimum of the objective function because criteria have different physical nature. There were chosen such objective criteria as depth of fuel burn-up, index of the fuel cladding damage and axial offset - the ratio of the energy at the top and bottom of the reactor core.
