Popis:	This work undertakes an analysis of the sources of error in modeling NPP and considers the influence of the basic components of this error on the accuracy of the calculation and the optimization of the indices of the apparatus. The analysis is conducted for the example of mathematical models intended for the prediction of the mass and dimensional indices and thermal economy (quality-evaluation criteria) of NPP as a function of their thermal-engineering parameters. The mathematical models of basic NPP developed for this purpose describe the physical, thermal, and hydrodynamic processes occurring in power plants and the principles of formation of their indices. The quantitative and logical relations between the NPP parameters are expressed by a system of a few hundred algebraic and transcendental equations in the form of power-law, exponential, logarithmic, and other functions and their rational fractions.
